You are welcome
Kevin: Looks like a condition often caused by loose connections and terminations. Did you recommend that some maintenance such as torquing be done by a qualified person?
Thanks for the recent seminars at the NACHI convention.
I ran into a weird condition in the main panel today. Panel had copper
branch wires that had turned black. The panel is about 4 years old.
Wire insulation was not black, bubbling or showing any other signs of
overheating. Normal temperatures found at all breakers and connections.
Per homeowner never lost power or had a lighting strike.
Any idea what might cause this?
