I have a Sears 25 gallon/4HP horizontal compressor. When I first turn it
on
it runs fine and shuts off at 150psi. The problem I have is when the
pressure gets at the level where it automatically kicks on again it then
pops the breaker off and I then have to reset the breaker before it will
run
again. I have a dedicated 20 amp circuit with 12/2WG using a Square D
breaker and a 20 amp duplex receptacle for the compressor, and nothing
else
is on this circuit. Do any of you folks have any suggestions as to how I
can
cure this problem? Thanks for your help.



Make sure the unloader isnt clogged and the check valve is working
correctly--when it shuts down, it should hiss for a couple seconds then
stop.

Otherwise it will be under too high of mechanical load on startup, not good
as it will draw too much electrical current.
