If you have to put two wires into the same terminal, either try to keep the
wire gauge the same so that the pressure is the same on both wires, or twist
the wires together before inserting into the terminal, which may be
difficult to insert the twisted wires without them untwisting, but you will
get a much better connection with equal pressure on both wires.

Thanks Doug,

This is copper wiring. I do notice on the buss bar that there are two
sizes of screw terminals. The ones containing two wires are of the
larger size. However, the point is taken. When I do my "housekeeping"
on the panel, I will try to keep it one wire per terminal. It does
look like, however, that there may not be enough terminals for each
circuit to be in it's own, but I'll get a closer look. The last time I
worked closely with the panel is when I installed a 50A breaker and
wired in a sub-panel for my finished basement.

It definitely seems like a poor connection on the buss since it worked
fine for a week after tightening it. However, this morning it was back
to flickering and arching.

Thanks for your help.
