The Science Behind Why AFCI Breakers Prevent House Fires
The Invisible Threat Within the Walls I remember my old foreman, a guy who had been pulling wire since the Eisenhower administration. He used to smack my hand if I stripped a wire with a knife instead of the proper tool. ‘You nick that copper, you create a hot spot,’ he’d scream over the sound…
A Homeowner’s Checklist for Recent NEC Code Updates
I recently walked into a ‘fully renovated’ kitchen where the flipper had buried four live junction boxes behind a custom marble backsplash.
