What have I done now?

I installed 6 can lights in the basement ceiling, dimmer switch on wall. Starting to drywall ceiling. Wouldn't you know it, as I'm cutting out the drywall inside the can, the tip of the saw went inside the socket for split second (I know, I know, I had removed the red safety cap because I was using the light, I forgot to put it back.) Spark, other ceiling lights go out. The breaker did not trip. Now none of the lights work.

What happened, how do I fix it?

To be positively certain that a C-B did not trip, I suggest a positive test-for-voltage at the terminals of the C-B's inside the panel. Next could be a GFI device in the circuit between the CB's and the fixtures.

Checked that:

Voltage at breaker ok, no GFI on line, just these lights.

Could I have fried something in the switch?

Test for voltage at the switch. If the switch-connection is 2 Black wires, test for 120 volts,Black-to-Whites.

It the switch-connection is a Black & White wire on the terminals, check Black-to-Ground and White-to Ground.

Ground (should be) either the metallic surface of the O-B , or a bare Grounding wire.

That's it...

I fried the switch. That was one stupid and expensive mistake to make.

Thanks for your help, Happy Thanksgiving to all.

You consider smoking a $20 switch an expensive mistake? I wish I was that lucky.

Don't use the fixed lights, use portable work lamps.
