All electric devices failed on one of my circuits in my house. The circuit breaker at the main box didn't look tripped but I find that it isn't always easy to see they've tripped. When flipping this circuit breaker back and forth, it feels a little "mushy" i.e. doesn't really seem to click on/off.
I'd like to replace this 15 amp circuit breaker rather that spend about $100+ for an electrician to do it. I've seen it done before, but haven't done it myself. Do you experts think it's reasonable for a non-electrician to be doing this? And, is my approach correct? My approach would be a. Turn off the "Main Breaker" at my box b. Remove the front of the circuit breaker box (4 screws, one on each corner) c. I'd find the old circuit breaker held in place by 2 screws ???? Remove it. d. Disconnect the wires from the old one and attach to the new breaker and reverse above steps.
Also, I have a multi-tester that will test for voltage up to 220. After exposing the faulty circuit breaker, I could test the circuit to see if it is in fact dead (I turned the "main" off), before working on it. Question is: I would attach the + side of the tester to either wire (testing both, I know one is coming in from the main and the other is going out to the circuit. I'd test each side to be sure I got the supply side) and the black side to what??? I could reach the black wire to the grounding wire outside the circuit breaker box that attaches to a copper pipe running into the ground, but wouldn't I have an uninsulated 110 v. current running there when testing. Is there an obvious ground inside the circuit breaker box that I could touch with the circuit tester black wire?
Thanks
