Thank you for reading my question. I am rewiring a 100 amp sub panel (that did function for years) because I originally thought one of two 110 breaker bars in the box had stop functioning.
Currently I have replaced the 100 amp electrical breaker box, rewired and installed all the breakers, yet the same problem exist. After further testing I determined:
With the sub panel wired, (with two 110 incoming hot, common and ground wires) both incoming hot lines and each breaker bar reads 110 volts. Yet when a single 20 breaker is installed on the right side breaker bar the reading falls to 0 (at the breaker, the breaker bar and the incoming hot wire), thus no power.
I have moved the same breaker to the left, utilizing the other breaker bar, and the breaker functions as it should.
I have tested the main panel that supports power to the sub panel and no problems exist in the breaker of panel itself.
I can't understand why I can have 110 volts at the sub panel, breaker installed, flip the breaker to the on position and one of the 110 bars goes dead, yet if I flip the breaker off all power is restored, or I can reposition the breaker to the pole next to it and everything functions correctly.
I apologise for not using correct electrical terms. Any help would be greatly appreciated.
