8/5/2023 0 Comments 220 plug for air compressor![]() ![]() I can also take pictures of my converter cord if you want. ![]() I have pictures of my motor, including the motor label with wiring diagram and another of the terminals with the cover off like you showed with your motor. I couldn't see what plug was on yours, but if it is a 240 volt plug, this won't be an issue for you. The WORST that can happen with my setup is some illiterate moran could plug the compressor in to a 120V outlet and try to run the motor wired for 240V. The guy I bought it from changed it over, so now it has a 220 plug on it. I have an air compressor (220v) that used to be hard wired into a house (before I bought it).These voltage ratings are essentially equivalent, so the. 220 volt switch for compressor 34053 Views 24 Replies 10 Participants Last post by powers, P powers Discussion Starter Then I built a 16" long converter cord that has a female 120V end and a male 240V plug (labeled 240V) that goes in to the 240V outlet below my disconnect/fuse box. The motor draws more current, and it runs more efficiently at 220, 230 or 240 volts than 120 volts. On mine, because I might want to switch it back to 120V, I labeled the motor with a big WIRED FOR 240V sticker and also placed one on the cord near the original 120V plug. That's it! You do NOT need to change how the on/off pressure switch is wired. Yellow wire T2 is removed from terminal 1 and moved to terminal 4. What I had to do on my Campbell Hausfeld is:įor 120V, yellow wire T2 is on terminal 1 and P2 is on terminal 4.įor 240V, yellow wire P2 is removed from terminal 4 and either taped over or placed in the blank terminal pocket 6. (please note, the internal wires T2 & P2 on my motor are yellow) It is possible that Campbell Hausfeld made that compressor for Sears way back when because Sears really don't make their own shit.īut the internal wires on your motor that are labeled T2 & P2 are probably the ones you need to change. The motor looks similar to yours and is a Doerr brand made by Emerson Electric. I recently changed my old Campbell Hausfeld compressor from 120V to 240V. I want to make it clear that I am providing no guarantees that this will work, and you assume all the risk. Without a label on your motor or the manual that came with the compressor, this could be a bit tricky. It wont let me add another picture but imagine an old 3 wire dryer or water heater plug. All the instructionals say that there should be 6 wires but i can't see a T1 anywhere.Īlso is this the correct plug for this type of service? It was an old dryer plug before I converted it to 4-wire. Much more inspection revealed that the wires are labeled P1-P2 & T2-T4. I spent some time on the internet & learned that the coils need to be changed from parallel to series ( makes sense). There is no diagram under the covers on the motor & any decals it may have had on the outside are long gone. I found a wiring diagram for the switch that seems to indicate that it indeed is intended to run on 220 (L1 & L2). I don't know if the motor needs to be re-wired or just put a new plug on the switch. I have had it for the last 18 years or so & just moved it to my new house.Īnyway he told me that it will run on 220 so I wired the new shop for 220 with 10-2 run. I think he got it about 35 years ago when we everything from Sears. ![]()
