I just experienced a melted connection nut on my new furnace where the neutral neutral wire from the circut box connects to the furnace. It requires a 15 amp circuit breaker.
One single seperate circuit wire to the furnace, 14 ga sheathed electrical cable with ground.It did not throw the breaker, just melted and shut down the furnace.
I cleaned it up and reconnected and it is working ok but I am still wondering if it is safe?? Checked wire back to breaker, nothing unusual.
Any suggestions as to why and safety in the future.Chuck
It sounds like the wirenut was loose and therefore you had some arcing in the connection. Is the lead from the furnace a stranded conductor? A stranded conductor should be stripped longer and wrapped around the solid conductor and then wirenutted. What size/color wirenut was it? What brand?
