Okay, one more time and hope I don’t get scolded, have compassion for the elderly! These configurations of the electric furnaces don’t make sense to me.
I keep finding too many of those smaller wires connected to those 60 amps breakers burned out. Those 60 amps breaker “act as disconnects” and are supply by 100 amps breaker from the service panel.
But there is no way that the 60 amps breaker will trip when there is an overcurrent on one of those smaller wires, usually the damage occurs at the female terminal connection, but many of those small wires don’t have the female terminal and are connected to the 60 breaker by the way of twisting the 3 or 4 wires and connecting in the breaker lug.
I know as I have been told that this is the furnace configuration, bla, bla, BUT if those wires keep burning out, it is because this is not the right configuration!
AND still it doesn't make sense to me, because 2 of those furnaces went already on fire.
