Burnt wires in power distribution panel
While tracing the cause of an intermittent electrical failure in an electrical circuit in our ORV 21RBS, I discovered that all of the neutral wires in the power distribution panel were 'burnt" where t...

MY rule when working on 120 volt Breaker boxes and Transfer switches, is, I tighten the screws as tight as I can get them. WAIT 30 minutes and then tighten again. Even solid core wire will "settle" a little. Stranded wire will settle a lot more. You will be surprised that you will usually get 1/2 to full turn on the screws after initial tightening. Doug
PS, the cause of neutral burning is the MAIN Neutral supply was loose and caused a heat build up and that heat build up caused the BUSS bar to heat up and expand slightly and then all Neutral wires then heated up and melted or burnt loose. ANOTHER cause is, in conjunction with loose wires, running on overloaded CG circuits that drop the line voltage. BOTH together will cause a problem, that is why it is important to tighten the wires in the Breaker box. Once done, it should not be needed again.
