Home electrical wiring help

[02 281 GT]

I've never done home wiring before, so I figured I'd see if any of y'all could help me out.

I have a 5hp Ingersoll Rand 60 gallon air compressor that runs off of 15 amps and 240 volts, however, there is no plug in the garage that can supply this power. I want to run a new plug straight off of the breaker box (which is in the garage already), and I'm just wondering if I have everything I need (and if I do, is it the right stuff).

Everything. Disregard the small gauge wire. That was for something else and kind of sneaked into this photo.

This is the kind of plug that the power cord requires.

The wire is wrong. You need 3 wire (red, black & white) with ground and minimum 10 gauge. The circuit breaker doesn't look correct either. you need one that is usually double wide for the 240v. Red will go to one and the black to the other. The electrical box is 4x4 as the two standard 240v plug receptacles are for dryers and stoves. The plug you use on the compressor must match the blade configuration of the receptacle. If the wires from the service panel to the outlet box are going to be exposed in the garage you will also need to use specially wrapped conductor. I don't recall it's name but it's usually black and you will need the compression fittings where it connects to the box and panel and clips to hold it to the wall.

Yeah, that's what some other people told me. I think I'm just going to call a pro on this one.

yea... its odd crap... i need the 240 for a powder coating oven :/

Yes the wire needs to be two phase conductors, neutral and a ground. The receptacle by amps and configuration needs to match the plug on the compressor, or you hard wire it. But if you hard wire it, you need a disconnect means with in sight or 25 ft, iirc. Also think you need a 30 amp breaker for a 30 amp circuit.

Also need to completely shut off the panel, and lock it out, when installing the breaker.

Also consider how you are going to get the wire to the box, ie, drilling and fishing through the wall. And cut a nice hole in the wall for the box.

I do most of my home electrical, but have a staff at work who can give detailed advice, and I have a bunch of books on wiring.

Remember to get some staples, or some other means to secure the wire after you run it.

Routing the wire would be no problem since it's in the garage. The side on which it would be routed has no drywall. I could just set up the plug and route the wire and get the pro to hook it up to the box.

Having no drywall really makes the job easy. Drill holes (3/4") in the studs from the service panel to where you want the plug located. Standard 10 gauge 3 wire + ground, plug and two 30A breakers. Connecting to the service panel assuming there is extra capacity available is easy enough. Trip the main (should be marked and at the top of the panel). Take the cover off punch out two adjoining knock outs where the two circuit breakers are going. Connect the red wire to one of the breakers and the black to the other snap them into the panel and wire the white to the neutral buss and the ground to where other grounds are connected. Put the cover back on, pin the two new breakers together, reset the main breaker and you're done.

toyman, good basic install instructions.

I took toyman's advice and upgraded to 10-gauge wire +ground and a twin-pole 30-amp breaker. Hooked it up tonight and it worked like a charm!
