Junction box with 3 circuits, one wire is damaged and its too short to pigtail. Do you think its easier to pull 6 #12 wires in 50' of 1/2" emt conduit by yourself? This is a homerun back to the panel. Theres a tight turn on the conduit and I am not sure I would be able to "push" the wire thru. Alternatively, I dont think I would be able to replace just the one wire without it getting hung up. vs cutting into the conduit and adding a splice box? Again this is emt and doing this I fear I dont have enough play in the conduits to squeeze it in... typically would you have to have some movement in the pipe to do this?

I have old fan which i recently serviced. For kicks i measured between the fans metal housing and a grounded conduit and i got like 30vac. My meter has a low z function and when i set it to that it read 0 vac. I trust that the the 30 vac was just ghost voltage. So why does that occur? Close proximity to the motor of the fan perhaps? Ungrounded non polarized plug? Is a low impendace meter fool proof?
