Installing surge protectors in your home is an easy way to protect your valuable electronics from power surges. Doing it yourself can save you money compared to hiring an electrician. Here is a step-by-step guide on how to properly install surge protectors in your home.
Why Install Surge Protectors?
Power surges are sudden and brief spikes in voltage on the electrical system. They can be caused by lightning strikes, grid switching, faulty wiring, or heavy appliance use. Surge protectors help regulate voltage and prevent excess electricity from reaching your devices.
Here are some key benefits of installing surge protectors:
-
Prevent Damage to Electronics - Electronics like TVs, computers, and appliances can be damaged by power surges. Surge protectors absorb excess voltage to prevent it from reaching your devices. This saves you from costly repairs or replacements.
-
Improve Safety - Power surges can also damage wiring and electrical systems, leading to potential fires. Surge protectors improve electrical safety.
-
Save Money - By preventing damage to electronics and electrical systems, surge protectors save you money in the long run. The minor upfront investment is well worth it.
Installing surge protectors is an easy DIY project that can provide major protection. Doing it yourself rather than hiring an electrician can save you at least $100 per protector.
Choosing the Right Surge Protector
Not all surge protectors are created equal. Here are key factors to consider when choosing one:
-
Joule Rating - This indicates how much energy the protector can absorb before failure. Look for a joule rating of at least 1500, though 2000 or higher is better for whole home protection.
-
Protection Modes - There are three main types of protection - L-N, L-G, and N-G. Choose a protector that offers all three for complete coverage.
-
UL Certified - Verify it has been evaluated by Underwriter's Laboratories for safety and effectiveness. This is a must!
-
Indicator Light - Choose a protector with an indicator light that alerts you if protection has been compromised.
-
Warranty - Select a surge protector with a warranty of at least 5 years, though 10 years is preferable.
A good whole home surge protector will meet these criteria while also offering high wattage capacity and at least 6 outlets. Spending a little more upfront on a quality unit will give you better protection and peace of mind.
Surge Protector Installation Location
Proper installation location is key to maximizing the effectiveness of your surge protector. Here are the optimal locations:
-
For whole home protection, install the primary surge protector in the main electrical panel or at the meter base outside. This will shield your entire electrical system.
-
For protecting sensitive electronics, install surge protectors directly at outlets where equipment is plugged in. This provides an added layer of localized protection.
-
Install outdoor surge protection at the air conditioning unit. This will protect the AC from surges.
-
Consider surge protection at the network interface device to protect phones, cable modems and networking equipment.
Installing surge protectors closest to the equipment being protected ensures excess voltage is regulated before it can reach your devices.
How to Install a Whole House Surge Protector
Installing a whole house surge protector is the best way to protect your entire home. Here are the steps:
Gather the Right Supplies
You will need:
- Whole house surge protector
- Electrical tape
- Screwdrivers
- Voltmeter
Ensure your surge protector matches your home's electrical system. You will need a protector capable of handling the amps supplied to your main panel. Consult an electrician if unsure.
Turn Off Power at the Main Panel
Switch the main breaker off to cut power. Always turn electricity OFF before working in the panel. Verify it is safe using a voltmeter before proceeding.
Connect the Surge Protector
Refer to the protector's installation guide. In most cases:
- Connect the surge protector to the neutral bus bar. This is the bar where all neutral wires terminate.
- Connect the ground wire to the ground bus bar.
- Connect the hot wire to the main lugs where the main power feed connects.
Use screwdrivers to securely fasten all connections. Neatly route the wires and use electrical tape as needed.
Close the Panel and Restore Power
With all wires securely connected, close up the electrical panel. Turn the main breaker back on to restore power. Your whole house surge protector should now be providing protection.
Installing Surge Protectors at Outlets
For protecting specific equipment, install surge protectors at the wall outlet they plug into. Here's how:
-
Unplug the device you want to protect from the outlet.
-
Plug the surge protector securely into the outlet. Make sure it is pushed all the way in.
-
Plug your device into one of the outlets on the surge protector.
-
For multi-outlet strips, keep coiled lengths neat and tight to prevent tripping hazards.
Do not overload the surge protector's capacity. Check the max wattage before connecting devices. Spread load over additional protectors as needed.
That's it! Plugging in a surge protector at outlets around your home provides an easy safeguard for sensitive electronics.
Safely Installing Outdoor Surge Protectors
Outdoor AC units and well pumps also benefit from surge protection. Here are some tips for safe installation:
-
Use weatherproof surge protectors designed for outdoor installation. Look for units rated for wet locations.
-
Mount the protector to a wall or other solid surface near the equipment using the included mounting bracket. This keeps it upright and stable.
-
Make wiring connections using special waterproof wire nuts. Use electrical tape as an added precaution against moisture.
-
Route wires neatly to avoid hazards. Use wire ties and anchors as needed to attach them securely.
Outdoor installs involve dealing with moisture and require weather appropriate surge protectors and connections. Taking the right precautions will ensure safety.
Troubleshooting Surge Protectors
Here are some tips if your surge protector is not working properly:
-
Check the indicator light. If not illuminated, protection has been compromised and the device should be replaced.
-
Test outlets with a lamp or other device. If equipment still doesn't power on, the protector may not be working.
-
Use a voltmeter to check for voltage. Lack of output can indicate failure.
-
Inspect wires and connections for damage or detachment that could cause interruption.
-
Try resetting the surge protector by unplugging it and plugging it back in. This may resolve simple issues.
-
Replace severely damaged or faulty surge protectors immediately to maintain protection.
Surge protectors can absorb only so many hits before needing replacement. Swap out damaged units to keep your home safe.
Installing surge protectors is an easy, cost-effective way to protect your home and devices. By following proper installation and safety procedures, you can avoid electrician fees and reap the benefits yourself. Protect your investments with surge protection.
