Question about Air Tools & Compressors
I bought a Husky brand compressor from Home Depot. It is a 3.2 HP, 60 gallon, and is to be wired for 220v. They don't come with power cables. The Depot man sold me the wire and corresponding plug. Under the pressure switch cover where it gets wired up, the motor side is already set, as the black and white wires from the motor are factory installed with spade terminals slid underneath the phillips head screws. The upper part for the power cord looks exactly like the spade terminals for the motor, but the Depot electrician said to not use any terminals, just put the wire in there and screw it down. The problem is, that the wire even when twisted tight, will not fit under the screw. I went back and he sold me some solder saying that the wires need to be soldered first. Well that still wont work, because the solder made the wire even bigger. I do not want to cut some of the strands off to make the wire smaller, since I am dealing with 230volts. I went to another Home Depot, and they said the same thing, do not use terminals on them. But the switch box is desigend for a spade terminal! Help!!
you can use terminal connector like on figures joint connector or lug connector
this are more convenient to use
easy to install and has insulated for connection.
insulated ring terminal connector
this is also good for connector more safe for circuit breaker suipply.
go to the nearest hardware or mall

I do not want to add to the confusion but I have installed several of these over the years and use a piece of romax or three pieces of #12 solid copper wire inside flextube or metal conduit. I believe that this unit is designed as a shop compressor and should be bolted to the floor and hard wired to a breaker/ switch on the wall instead of using a plug/ receptical. Hard wiring and bolting to floor reduces theft and reduces chance of tipping over. The solid copper wire fits nicely on screws of pressure switch. All these parts are available at Home depot; speak to one of the electrical guys about your project. If you would rather use a pigtail, I would definately use terminals soldered to copper strands and do not remove any strands. Find a terminal for your wire gauge that fits the pressure switch. Soldering is much better than crimping. Run you compressor for a while and unplug or switch off. Remove the cover to the pressure switch and carefully feel the connections for heat. Excess heat means loose connection. If unusually hot, remove connector and carefully resolder. Good Luck with your new compressor and email if you have question.
