I need a little help. I bought a 7.0 hp, 80 gallon, 240V, single phase air compressor last week. When it got here I connected a heavy duty appliance cord to it and plugged it into a 240V outlet. It fired up right away and ran for an hour to break it in per the owner's manual. No problems. I wanted to install a switch so I didn't have to unplug it when I didn't want it to run. I went and bought a 60 amp, 240V safety switch thinking that would be adequate. I wired up the safety switch but when I turn it on it trips the breaker on my breaker panel. I thought, and this is probably where my mistake is, that the 240V circuit ran through a 40 amp breaker. I thought I would be alright with a 60 amp safety switch. Turns out it's
*two* 40 amp breakers. I've got it wired from the outlet->heavy duty appliance cord->safety switch->8 ga. wire->pressure switch on the compressor. The manual said to use 8 gauge wire to the pressure switch. What's the best way to install a switch between the outlet and the compressor? Do I need a higher amp rating safety switch? I'm 99.9% sure I've got everything connected right and grounded properly.Thanks, Bud
