Blown Circuit? Helping a friend and blew it . . .


I was installing under-cabinet lighting at a friend's house and tapped it directly into a kitchen plug. Everthing worked fine but then I accidentally shorted the wire by cutting it while it was plugged in. The plug that arc'd still worked so I thought all was well. I later discovered that an adjacent room's lights and plugs no longer work.

The breakers are all fine, even found the breaker for that room and plugged the wire in the breaker box into another breaker - still wouldn't provide power.

So how do I find what I blew? Or what are the possible problems I can check. When I cut the wire, it popped and blackened the cord but the immediate plug still worked.

thanks, it's a bit embarrassing to not be able to find it.

Oh - and it's not a GFI switch - that was fine.

Start at the breaker and make sure the breaker is good using an electrical meter.

Then your only option is to start opening boxes to try to find a splice that has come apart. I would start with the box where you plugged in the UC lughts. Be careful!! because you might have an open neutral and could still get a shock from a hot wire. Again, with a meter you can check for that by going from hot to ground.

Also the lighting should not be on the kitchen small appliance circuits.

If these lights are factory produced with a cord and plug they cannot be hard wired. This project sounds bad from every angle.
