air compressor power switch feedback ?

[mogandave]

just to make sure as these dont come with any instructions at all .......... i feed 240 to the coil 1 leg per coil tab ?

my plan was the 220 cord from wall plug to 1 side of new relay . also pull power from there to feed to new pressure switch . then back to coil tabs and last the relay out to motor .

That's what I would do. Good luck!

What switch did you end up getting?

If the compressor is a permanent installation, you could put the switch and contactor in a box on the wall and just run a piece of SO cord to the motor.

Keeping it reg setup for now . Got a box to add on compressor to hold the mag switch .

Well almost 400 days and the BIG compressor is back up and running . Glad i had a good size backup tho . . . Life got in the way plus procrastinating a LOT . And worst part the parts were here the whole time

Used this old box from an industrial unit as my new mag relay box . Used 2 beam clamps to mount it to my plate . Then used a chunk of 14/4 for a clean 2wire in / out of the new pressure switch back to the mag relay . i also crimped ends on the big wires so its not all that fine strand on the big pinch screws for the relay .

then covered it up with the old cover and left the original stuff for looks and kind of mix-n-match / steam punk .

Hooked up the power and she fired right off and didn't skip a beat .

Thanks to all who helped and gave me a link to a nice little unit and saved a chunk of money over a full mag box unit .
