First, make sure you do not have 20A breakers on 14 guage wire. If you
do, change them to 15A breakers now. Thats what could be causing your
conduit to get hot.
Hot conduit is NOT a sign of wrong amperage breakers! Hot conduit
means there is a LOT of current trying to find earth ground!

Actually, it's much more likely to mean hysterisis heating.

Huh? As in magnetic? What's being magnetized?

The OP mentioned loosening the conduit fitting and getting a spark.
That says to me that the conduit is carrying current.
