Blown fuse - won't reset and then a spark!


Hi all,

Turns out running my halogen light on the same circuit as my 4hp compressor is a bad idea. huh.

It blew, so I turned off/unplugged things and went to reset it - nothing doing. Still goes straight to "trip".

House is a 1970, with Aluminum wiring (I know....).

I went back over today to flip it and saw a spark behind the panel. I'm guessing when I open the panel they'll be some melted/fused wire. Does that sound right?

I have no hard cutoff to the house, so I'll have to have a pro do the repair - any advice on getting a new panel/master cutoff installed? What would you do in this situation?

Thanks

If you're gonna hire a pro, let them do the guesswork. They're good at it

No. Seeing an arc at the panel is pretty standard when you have a direct short.


You haven't cleared the fault yet. Turning something off doesn't always solve the issue. You need to unplug everything from that circuit to determine if the problem is with the equipment or the home wiring.

Thanks for the note. I'd unplugged most things, but will make sure all outlets are empty. I'm worried since the compressor and halogen aren't plugged in anymore that there are "real problems"

I'll give it a shot tonight

Well,

GFI was kicked on the outlet behind a desk, interrupt was also kicked on the surge strip that was plugged into the outlet. Between those and what appears to be a faulty circuit breaker (sits on 'trip'), I was confused but now we're back to normal.
