What is a surge arrester and how does it work?
A surge arrester is a device wired into your electrical panel that catches a voltage spike and diverts it to the ground before it travels through your home's wiring. A plug-in surge protector guards only what's plugged into it. An arrester protects the whole system from the point where power enters your house.
Why can't I just use power strips with surge protection?
Power strips only cover the devices plugged into them. Your AC, water heater, oven, and anything else that's hardwired get no protection. A surge arrester at the panel covers every circuit in the house.
Are surge arresters necessary in areas with frequent storms?
They can be especially useful in areas like Tampa that experience frequent thunderstorms. Lightning and electrical grid issues can cause voltage surges that damage appliances, electronics, and other equipment in your home. A surge arrester adds another layer of protection.
How much does surge arrester installation cost?
It depends on your panel, the arrester your home needs, and how easy it is to access the panel. Our service call is $175 for the first hour of labor, with materials priced separately. We'll show you the full price before any work begins.
How long does installation take?
Most surge arrester installations take one to two hours. Your power will be off briefly while your electrician works inside the panel, and you'll be protected before we pull out of the driveway.
How long do surge protectors last?
It depends on how many surges the device absorbs. Every hit wears it down a little, and a single severe surge can use it up. Most units have an indicator light that tells you when it's time to replace it, and we're happy to check yours after a rough storm season.
Can a surge protector stop lightning damage?
It stops most of it. A surge arrester handles the spikes that travel through power lines when lightning hits nearby, which is how most lightning damage reaches a home. No device can fully stop a direct strike on your house, which is where lightning arresters and proper grounding come in.
Do I still need surge-protecting power strips?
They're worth keeping. Think of the arrester as your front door lock and the power strip as a second lock on the room with the valuables. Together they give sensitive electronics like computers and TVs two layers of defense.
Will a surge protector protect my HVAC?
Yes. Your AC system is hardwired, so a power strip can't help it. A surge arrester at the panel protects the compressor, air handler, and control board, some of the most expensive parts in your home to replace.
Can I install a surge arrester myself?
Plenty of videos show how to install a surge arrester, but the work happens inside a live electrical panel. One wrong connection can mean shock, fire, or a device that fails silently when you need it. Leave this one to a licensed electrician.
