Safeguarding From Power Surges
External (coming from outside the house)
AND
Internal (coming from inside the house)
Note: A Power Outage — Is Always Followed By A Power Surge.
During the blackout — electricity lines carry no electricity. When power is restored — a surge of electricity races into & through the lines.

NOTE: Without a Whole-House Power Surge Protector — The Only Way To Protect Your Home & Devices From A Power Surge
Is To Turn Off The Main Circuit Breaker — In The Circuit Breakers’ Panel.
THEN: After Power Is Restored — Wait 5 minutes before turning the Main Breaker back on.
NOTE: The Main Circuit Breaker is the large one above the small ones shown above. When the main breaker is off — electricity is shut off to the entire house.
Otherwise, During The Outage:
- Turn electronics (protected by surge protectors) off.
- Unplug major home appliances (most have circuit boards).
- Turn the HVAC System off at the circuit breakers — there’s 1 for the A/C & 1 for the furnace (HVAC Systems have circuit boards).
Safeguarding From Both External & Internal Power Surges
Requires Two Levels Of Defense
- A Whole-House Surge Suppressor(s) — to stop external power surges.
- These suppressors are located at the meter OR inside the circuit beakers’ panel.
- Individual “Plug-In” Surge Suppressors — to stop small, internal power surges.
- Other than disconnecting power the only way to protect your home and electrical devices — is with power-surge protectors/suppressors.

Whole-house surge protection can be integrated at the electric meter OR within the circuit panel. It will stop the surge from entering the home IF that’s the entry point (which is most of the time). If the power surge enters the home from any other location (other than where electricity comes into the home) damage will occur — up until the power surge reaches the surge protector. Also, whole-house surge suppressors protect the home from a power surge from the electric/power grid.
When storms approach with numerous claps of thunder — you can unplug electronics and appliances to protect them. Keeping abreast of approaching storms, and the predicted severity of lightning, is possible through several like DFW’s Fox 4 Weather App. (for phones). It has optional information layers — such as where lightning strikes have quite recently occurred.

SHOWN: A direct or nearby lightning strike produces the largest power surges. There are also many other sources (discussed in Part-1 of this article).
No one knows when or where lightning will strike — when it does, it can cause substantial damage to; home’s circuit breakers’ panel & wiring, appliances, and electronics in a home. In 2018, The Insurance Information Institute reported $909 million in lightning claims were paid — to nearly 78,000 policyholders.
A nearby lightning strike can enter a home through; metal pipes, home electrical wiring, phone, internet, and cable TV wires. Once inside the home, a lightning strike’s power surge may cause a fire in electrical wiring behind walls, or in ceilings. Damage potential extends to major home appliances (washers, dryers, refrigerators, range) as most newer ones have control boards to operate it. In addition, more circuit boards are inside; furnace, central a/c (or heat pump). A power surge can also damage an electric car while it’s charging.

Al’s Plumbing, Heating & A/C Does Not Sell or Install Surge Protectors.
An Electrician Is Required.
ON A SIDE NOTE: During A Power Outage
An ELECTRIC Car Can Provide A Temporary Heated/Cooled Environment.
With An ELECTRIC Car — during a power outage, run only its climate control system. Because an ELECTRIC car produces no emissions — it’s safe to sleep in it (even within a closed garage). And, if you can reach a charging station with power — recharge it there.
Note: None Of This Applies To Non-Electric Cars.
Safeguarding From External Power Surges
Choice 1: Whole-House Surge Protector — Located At The Electric Meter.
You can protect your home’s electrical wiring, and everything connected to it, from EXTERNAL Power Surges with a Whole-House Surge Protector.
NOTE: These require a licensed electrician to install them.
A Comprehensive Power Surge Protection Strategy Incorporates Up To A 3-Tier Approach:
ThisOldHouse.com — suggests 40,000 amps (minimum) Whole-House Surge Protection. It’s expressed as: 40kA = 40,000 amp.

NOTE: This Must Be Installed By A Licensed Electrician.
1st-Tier Surge Protection — blocks an external power surge outside the home. It sits under the electric meter.
- It’s Called: “Type 1”.
- These protect against only External power surges. They can’t protect from internal power surges — created inside the home.
- This type sits between the power meter and the house
- It Must Be Installed By a Licensed Electrician.

Safeguarding From External Power Surges
(Come From Outside The Home).
Choice 2: Whole-House Surge Protector — Located Inside The Circuit Breakers Panel.
2nd-Tier Surge Protection — blocks an external power surge from entering the Circuit Beaker’s Panel.
- It’s Called: “Type 2”.
- These protect against only External power surges. They can’t protect from internal power surges — created inside the home.
- It’s installed inside the Circuit Breaker’s Panel.
- It Must Be Installed By a Licensed Electrician.
Rated At: Maximum Surge Current: 65kA (65,000 amps).

(NOTE: The article’s photo appears to show a power-strip versus surge-protector. Most (if not all) surge-protectors have overload-protection. Many power-strips don’t.)
3rd-Tier Surge Protection — Blocks only Internal Power Surges — between the outlet and all devices plugged into the surge protector.
NOTE: Plug-in Power Surge Protectors don’t have the capacity to block a large, external surge.
- It’s Called: “Type 3″.
- These are for Small, Internal power surges.
- YOU install them — by plugging them into an outlet.
Note: They’re available in either 120-Volt & 240-Volt versions.
Safeguarding From Power Surges — Up to 3/4 Of Power Surges Come From Inside The Home.
- Internal Power Surges occur when high electricity-demand devices turn off.
- Because many high-demand devices are controlled by a thermostat — they cycle on & off many times each day.
- Window Air Conditioners, Electric Heaters & Hair Dryers — are the 3 most common sources of internal power surges.
- Power surges may also be created by older refrigerators and freezers.
- Newer refrigerators & freezers consume a fraction of the electricity as older ones.
Safeguarding From Power Surges With Plug-In Surge Protectors
To Protect From Small, Internal Power Surges
If you’ve seen a light bulb become brighter for a brief moment — you’ve witnessed an internal power surge.

- Only A Whole-House Surge Protector Stops External Power Surges (coming from the Power-Grid) from coming into your home.
- A Whole-House Surge Protector Does Not Protect From Internal power surges.
- 3/4 Of Power Surges Are Internal (coming from inside the home).
- Internal Power Surges — occur when a high electricity demand device turns off.
- When the device turns off, the electricity (flowing into that device) — has nowhere to go for a brief moment.
- In response — the home’s wiring reroutes that excess power into the ground wire.
- From there — that excess electricity is routed into the ground under the home.
- During that moment before the ground wire routes that excess electricity away — an Internal Power Surge occurs.
Safeguarding From Power Surges — A Plug-In Surge Protector protects electrical devices from internal power surges.
Note: Large-Demand Surge Protectors are available for high electricity-demand appliances (details just after the photo below).
- Nearly every electric device has electronics.
- The few exceptions are devices with non-electronic controls — like a fan.
- If there’s a Digital Readout — the device has electronics.
- Nearly all newer appliances & all HVAC Systems have sensitive electronics.
- If in doubt if an appliance/device needs a surge protector — it’s best to add one.

Safeguarding From Power Surges — For High Electricity-Demand Devices
A Combo Power Surge Protector + Electricity-Stability Protection
- This type of protector is for; Window A/C, Refrigerator, Washer, (gas) Dryer, (gas) Range, Home Theater, expensive computers & other expensive electrical devices.
- This surge protector blocks power (to a device) — while it tests the electrical current for stability.
- This protector provides this additional layer of protection.
Note: It’s common for electrical current to be unstable for a short time after a power surge.
SHOWN: Delay Surge + Brownout Protector

NOTE: A “Brownout” is when the Electricity Provider Lowers The Voltage during very high electricity demand. — versus beginning Rolling Blackouts.
This protector Has 3 Lights:
- Red = Protector is booting up.
- Yellow = Protector is testing the stability of incoming electricity.
- Green = Protector is allowing current to what’s plugged into it.
NOTE: Power Strips Do Note Provide Surge-Protection

- Overload Protection (with a circuit-breaker) Is A Feature Included With Some Brands & Models Of Power Strips (the more expensive models).
- It protects the power strip from becoming overload and creating a fire-hazard.
- It doesn’t protect what’s plugged into it from power surges.
- If it doesn’t say it has overload protection — Assume That It Doesn’t.
Plug-In Power Surge Protectors Are Not All Created Equal

How Does A Plug-In Surge Protector Work?
- When the electrical voltage rises above a safe level — a Plug-In surge protector diverts the Power Surge into the home’s ground wire.
- This prevents a power surge from reaching devices plugged into it.
Note:
- Plug-In Power Surge protectors — Don’t Protect From External Power Surges.
- They are designed only for Small, Internal power surges.
One of the biggest concerns with Plug-In surge protectors — is if they disconnect power (to what’s plugged into them) if they become compromised. The only way to be sure is to read the marketing information provided. If they don’t say it disconnects power, Assume That It Doesn’t.
Tripp Lite Brand Plug-In Power Surge Protectors Cut Power If They Become Compromised. This brand also comes with insurance to replace protected items if the Trip Lite power surge protector fails to protect them.
This Verbiage Came From Tripp Lite’s Website:
(www.tripplite.com) Under The Heading “Premium Safety Features”: “Automatic Shut-Off Cuts Power To All Surge Protector Outlets when the protector has been compromised.” Tripp Lite sells surge protectors with 1 outlet to many outlets.
The direct plug-in protector shown below doesn’t have the capacity to protect; refrigerators, washers & (gas) dryers, or (large) microwave ovens. They require a high-demand protector (shown earlier within this article).
Note: Al’s does not endorse a specific brand of Surge Protectors only because we lack first-hand knowledge of all devices available.

Note: If You’re Certain Your Home Has Grounded Wiring (or was built after 1961) — Scroll Down To The Next Double Lines.
Safeguarding From Internal Power Surges Isn’t Possible
In Homes Without Grounded Wiring (pre-1962).
Image Source: Shutterstock
SHOWN: Most Homes Built Before 1962 — Didn’t Have Grounded Electrical Wiring
(Like this Levittown, NY home — built during 1947–1951).
Electrical Outlets Without A Rounded-Top Hole Below The Two Slots — Aren’t Grounded.
Image Source: Shutterstock
SHOWN: Ungrounded Electrical Outlet
- NOTE: A Plug-In Surge Protector has 1 job: detect excess voltage — and divert it into the ground wire (inside the walls).
- With ungrounded electrical wiring — Plug-In Surge Protectors Can’t Work & Offer No Benefit.
Beginning in 1962 — The National Electric Code (NEC) Required Grounded Wiring & Outlets
Image Source: Shutterstock
Shown: Grounded Electrical Outlet
TIP: If A House, Built Before 1962 Has Grounded Electrical Outlets — Don’t Assume Its Wiring Is Grounded.
- The original outlets may have worn out — and replaced with new, grounded outlets (ungrounded outlets are no longer available).
- Today’s appliances & electronics often have a grounded plug.
- Replacing an ungrounded outlet with a grounded version — accommodates grounded plugs.
A Simple Outlet-Tester Indicates If An Outlet Is Grounded
(see yellow devices just below).
- An Outlet-Tester Is A Wise Purchase If You’re Considering Buying A Home Built Before 1962.
- Plug into an outlet to determine if it’s grounded — before writing a purchase offer.
- A Home Inspector will test for grounded wiring — but the inspection occurs after the seller has accepted your offer.
- Many older homes do have updated, grounded wiring.
- Updating the wiring is possible — but it’s expensive.
- The average cost to rewire a home is around $2.75+ per square foot of living space. **
- For a 2,000 square foot home — Expect to pay $5,500+ for rewiring. It’s also likely you’ll want additional outlets — since older homes don’t have many.

Additional National Electric Code (NEC) Updated Requirements Through The Years
Note: Most municipalities match their electrical codes to the National Electric Code. It’s best to assume your city has NEC-based codes.
NEC Code Beginning In 1962:
- Grounded wiring & electrical outlets throughout the home.
- These requirements increased protection from electrical shock in the event of a short-circuit.
- During A Short-Circuit– A Person May Become Part Of The Electricy’s Path.
Exceptions To The 1962 Electrical Code.
- Existing installations without grounding.
- Those homes are not required to have grounded wiring — because they were built before the 1962 NEC electrical code went into effect.
- All electrical wiring updated after 1961 — must be grounded.
A Home Without A Grounded Electrical System
Can Be Made Much Safer (with its existing wiring) — By Adding GFCI Outlets.

SHOWN: GFCI Outlet
TIP: Amazon sells a 10-Pack of GFCI Outlets — with each costing about 1/2 the price of a single outlet.
Image Source: Amazon.com Embedded Link
Click On Image To; View Product, Read Details, or Purchase From Amazon.com
SHOWN: 10-Pack Of GFCI Outlets
- The N.E.C. (National Electrical Code) DOES allow GFCI outlets — to replace two-wire, ungrounded outlets (in existing homes).
- One of the least expensive & best ways to improve the safety of ungrounded wiring — is to install GFCI (Ground Fault Circuit Interrupter) Outlets.
- A GFCI outlet trips off if it detects a surge of power through the outlet. This dramatically reduces the risk of electrical shock.
- Without grounded wiring — GFCI outlets should be in every outlet location in; baths, kitchen, laundry, garage, basement or crawl space, & outdoor outlets.
- In other areas, GFCI outlets would be ideal — but the cost of installing GFCI everywhere might not be justifiable.
- If the GFCI Outlet trips — it’s reset At The Outlet.
TIP: With Ungrounded Wiring — If only 2-prong plug electrical devices are using an outlet — a GFCI outlet at that location offers limited benefit (if any).
SAFETY TIP: With Ungrounded Wiring — Buy Only electrical devices with 2-Prong Plugs. Those are double insulated and won’t shock the user.
SAFETY TIP: Never Break Off A Grounded Plug’s 3rd Prong.
The device is not double-insulated and, without the 3rd prong — it now poses
an electrical-shock hazard.
Electrical Devices Without A 3-Prong Plug — Are Double Insulated.
Note: This toaster is Double-Insulated — its website page shows a two-prong plug.

NEC Code Beginning In 1987:
Ground Fault Circuit Interrupter (GFCI) Outlets Required For Any Oulte Within 6 Feet Of The Kitchen Sink.
NEC Code Beginning In 1996:
ALL kitchen countertop outlets must be GFCI.
NOTE: GFCI outlets are the only version sold now.

NEC Code Beginning In 1999:
Note: This Code Became Effective On January 1, 2002
- ARC-Fault Circuit-Interrupter (AFCI) Circuit Breakers became required — Only For Bedroom Outlets.
- An AFCI breaker detects and stops a hazardous electrical arcing condition (defined below) — before it can cause an electrical fire.
- The AFCI Circuit Breaker’s requirement was a direct response to a U.S. Consumer Product Safety Commission report (conducted by Underwriters Laboratories (UL) that identified electrical problems were causing numerous residential fires.
The Ever-Increasing Use Of Consumer Electronics Led To Stricter Electrical Codes — Because Of Increasing Demand On Electrical Circuits.

Shown: Electrical Arcing
- Definition: Electrical Arcing — is when visible electrical current jumps a gap & flows through the air.
- Electrical Arcing has a high potential to cause a fire.
- Electrical Arcing — usually occurs when a circuit becomes overloaded and overheats.
- Overheating can damage the Circuit Breaker — and its connection to the Circuit Breaker Panel’s Bus Bars (definition just below).
- If damaged, a Circuit Breaker may malfunction — and continue to allow electricity to flow instead of tripping.
- Definition: Bus bars are thick metal bars inside the Circuit Breakers’ Panel.
- Bus bars receive electricity, from wires connecting the outdoor electric meter, into the Circuit Breakers’ Panel.
- Circuit Breakers snap into place onto one or both Bus bar(s).
- Each Bus bar receives a 120-Volt electrical current.
- Two 120-Volt currents — create a 240-Volt Electrical Service.
- 240-Volt Lines Are Required For; Central A/C or Heat Pump, (electric) Furnace, (electric) kitchen range, (electric) clothes dryer — and perhaps additional high-demand devices — such as an electric pool heater and some models of pool (filtration) pumps.
NEC Code Beginning In Beginning In 2002:
NEC Code required GFCI outlets (both 120-volt & 240-volt) — at every outlet within GFCI-required locations (see just below).
- Bathroom
- Kitchen
- Laundry Area
- Basement & Crawl Space
- On The Exterior Of The Home
- Garage & Outdoor Accessory Buildings
- Other Damp or Wet Locations — such as near a swimming pool.
Source: https://iaeimagazine.org/features/systems/gfci-protection-and-the-2020-nec/
NEC Code Beginning In 2014:
- The National Electric Code (NEC) required Arc-Fault Circuit-Interrupter (AFCI) Circuit Breakers for ALL Electrical Circuits In; Kitchen, Dining room, Laundry area, Living / Family / Recreation room, Bedrooms, Closets, Hallways + “similar rooms” (as defined by NEC Code).
- In wet/damp locations (kitchen, laundry, outdoor, garage, basement & others) — a Combo GFCI + AFCI Circuit Breaker Is Required.
- Note: This NEC code change, in essence, requires AFCI Circuit Breakers throughout the home (with quite limited exceptions).
