220 breaker off, still live
I'm working on a well pump problem--pump won't turn on. We replaced the pump 6 months ago, so I'm hoping it's not that.
Anyway, uncapped the wires leading down to the pump and put my voltage tester on the red and black wires coming from the fuse box. With the breaker off I'm getting 105v. With it on I'm getting the same voltage. I know I have the right breaker off because I replaced the pump earlier this year.
Can a breaker be in the shut off position and still be live?
For the record, I placed the voltage tester on the 220 30 amp breaker in the house and both poles are fine.
Thanks.

Ray,Technically shouldn't it be 125/250 I have never seen fuses or breakers rated as 120/240, it's strange that there is never any deviation from 277/480.
Just Saying!

Standard voltages are 120, 208, 240, 277, 347, 480, and 600.
The ratings you will find on equipment will be the same, or higher, then nominal voltages. You use 600 volt rated fuses/disconnects for 277/480 volt systems.
