things stopped working w/o tripping breakers
I just rewired a whole room. Everything is quite straightforward.
I used breakers #1-#12. Other than 2-4, and 6-8, which are used for 240V heaters, everything else is just plugs.
This morning, it was cold, 240 heaters and small 110 heaters are all cranked up. Then, everything stopped working, but the plug on #1and #12 breaker.
Also, there seem to be some small voltage going to some other plugs and the lights can be lit but very dim.
1. am I right in saything that it is probably one of the main fuses that was burt, and caused one pole of the main 240 entry stopped working. (I am going to investigate the main fuses right away.)
2. am I right that #1 and #12 is on the same pole that is still working?
3. Assume it one pole's fuse that got burnt. Why only two plugs on the still working pole is still working?
thanks a lot
Sounds like you have a neutral problem. Check for loose neutrals if you throw a meter on your outlet and get a strange voltage 70-90v it is more than likely a neutral.
Are you sure that it's just the #1 and the #12 that are working?
Measure the voltage at each and every breaker screw (where the black or red wire is fastened) and write it all down. Any patterns such as every other breaker having a strange voltage?
OP, If you are going to work with, and troubleshoot, electrical problems you will need a meter. You said breakers 2/4 and 6/8 are two pole breakers so just measure the voltage across the two connection points.
checked plugs , its 10-15volts,
checked neutral connections, don't see anything loosen.
checked main fuses, burnt one.
changed both fuses everything working again.
its a 60a fuse.
still, why only 2 of all the plugs on the unburnt fuse were working？
