Whole House Surge Protection in California

A device at the panel that clamps spikes before they spread.

A surge device at the panel costs 350 to 800 dollars installed and protects everything downstream of it, not just what is plugged into a strip.

The short version

  • Most damage comes from small repeated surges, not lightning.
  • The panel device and a plug in strip work together.
  • It needs a ground that is actually good to work at all.
  • Devices wear out and most have a light that tells you.

What it does

A surge device sits at the panel and shunts voltage above a set level to ground. It reacts in a fraction of a millisecond, so a spike from the street is knocked down before it reaches your circuits.

That covers things a power strip never does. The oven board, the air conditioner, the dishwasher, the garage opener and anything hard wired.

Where surges come from

Lightning is the famous one and the rarest here. Most of the damage is from switching on the utility side, from the pole transformer feeding your street, and from large motors in your own home starting and stopping.

Those small hits do not kill an appliance at once. They shorten its life, which is why the failure never looks like a surge when it finally happens.

Layers

The panel device handles the big energy. A good plug in protector at the desk or the media wall handles what gets through and protects the sensitive electronics. Neither replaces the other.

Both depend on grounding. In a home with no real ground or a corroded ground connection, a surge device has nowhere to send the energy. That is why an electrician checks grounding before quoting one.

Questions people ask

Does it protect against lightning
It helps with a nearby strike. A direct hit on the house is beyond any device.
How long does one last
Five to ten years, or less after a big event. Most have an indicator light, so look at it now and then.
Can it go in any panel
Almost any modern panel. Some take a breaker style unit and others mount beside the box.
