Two wires under one screw is a fire risk. Neutrals carry every bit of power a circuit uses back to the panel. They heat up and expand, cool down and contract, and over time that works the terminal loose.

Code now requires one neutral per terminal. If your panel was wired the old way, it's worth a look. Call David Williams Electric. ⚡

Surge protection is not lightning protection. It's built for surges and brownouts from the power line — the kind that can fry anything with a circuit board in it, which is nearly every appliance you own.

One surge can take out every TV in the house. One whole-house surge protector at the panel protects all of it for a fraction of what replacing them costs. Call David Williams Electric. ⚡

That flip-up cover on your outdoor outlet is obsolete — and no longer legal. Code now calls for an in-use "bubble" cover that closes over the cord while it's plugged in, keeping the weather out of the electricity.

It's an easy upgrade, and we'll replace the receptacle and seal it while we're there. Perfect timing before the holiday lights go up. Call David Williams Electric. ⚡

Whole-house surge protectors are now required by code — but that doesn't mean your home has one. A power strip only covers what's plugged into it. A whole-house unit installs at your panel and protects every circuit in the house.

With bigger storms hitting our area, it's worth a conversation. Call David Williams Electric. ⚡

Before you plug in that space heater: a 1,200-watt heater pulls 10 amps on its own. On a 15-amp living room circuit, that leaves under 5 amps for everything else already running — TV, lamps, chargers, the ceiling lights. That's how circuits get overloaded.

If you're running heaters this winter, a dedicated circuit is the safe answer. Call David Williams Electric. ⚡
