Hey Folks, I have a quick question. Did I do this right? The compressor motor is a single phase with a magnetic starter. The front two screw posts are from the outlet. The motor leads go on the spade terminals directly behind those. I’ve never wired up a mag starter before, but I went on the interweb and found a wiring diagram. I just want some piece of mind before I burn my barn down.

U mentioned an outlet?

Whats the HP rating of the compressor?

Looks like the red wire is going from L1 to L2- is that the case?

Wheres your pressure switch wires?

Wheres the wires from the overload relay?

L1 and L2 are power in. T1 and T2 are to the motor. The yellow crimp spade is from the pressure cut-off and is connected to the lug right behind L1. L1 is NOT jumped directly to L2. The overload is the red wire that goes from the reset up to spade lug directly behind L2. The other pressure disconnect goes to the very back spade lug on the L2 side. I hooked up power to L1 and L2 and moved the one pressure cutoff (the yellow spade) to the spade behind L1.

Too Little Information.

Post up MORE PIC's . . . . like the compressor, motor plate, etc.

What wire are you using to power the compressor ?? How far from Subpanel ??

I pulled a 220v single phase single stage out (the tank rotted out, should have fixed the drain years ago) and replaced it with a 220v single phase two stage (and an easy access drain). The cord is 5' long and is what came with the old compressor. I'll get more pics.
