relative newbie here.
I was upgrading a light fixture and at the same time installing a dimmer switch. I accidentally purchased a 3-way switch instead of the required 2-way switch and my "helper" removed the "insulating sticker" that covers the pole used for the 3-way switch and I didn't notice.
I installed it, flipped the breaker back on and went to test out the light. When I did, I could almost immediately smell a faint burning smell (really bad smell). I went back, turned off the breaker, and pulled the switch back out. The extra pole had come in contact with the box.
I took it out, replaced the "insulating sticker" and screwed the pole in so it isn't sticking out.
- Is what I've done safe?
- Is that insulating sticker really the protection against something bad?
- Shouldn't the breaker have tripped if a "hot" pole came in contact with the grounded box?
- My wife can still smell the foul smell - does that smell linger or do I have a bigger problem?
