Don't overlook the incoming power feed.


Yes, I will definitely check that. My incoming power lines are
connected to the electrical panel with Allen style set screws. They
are before the main breaker, so, I will have to be very careful
tightening them, as they cannot be turned off.

Those things scare the HELL out of me, and I work on live 240 V gear
all the time. I can't think of ANY safe way of tightening those, without
making a special tool. If that L-shaped allen wrench touches anything
else,
like the electrical box, the explosion will be totally awesome, and you
don't want to be anywhere near it. If you are not familiar with the term
"arc flash" you might want to read up on it. A 240 V residental service
doesn't really supply the watts that can get into serious arc flash
territory,
but it could still send you to the hospital.

I'd avoid using an L shaped allen wrench. I used a straight ball driver
with a large insulated handle on it.
