Surge protection
A whole-house surge protector at your electrical panel helps protect everything wired into the house from power surges. Martinez Electric LLC installs them. We’re based in Derry, NH and take jobs in New Hampshire, Massachusetts and Maine.
What’s included
A plug-in power strip only protects what’s plugged into it. A whole-house surge protector is wired in at the electrical panel, so it covers every circuit in the house, including the ones that feed appliances, heating and wired-in electronics.

Worth knowing
Surge protection helps against the everyday surges from the grid and from big appliances switching on and off. No surge protector can promise to stop a direct lightning strike.
