PostSubject: Any Electricians??   Sun 28 Sep 2008, 10:59 am

This is a conversation I am having with someone else on another forum, I'm just copying it so anyone here can double check what this guy is telling me..

Quote, Me

Ok, So I bought a new air compressor and I need help wiring it up. It's going to be put on a dedicated circuit and I need help with how to get started. I need to know what breaker to get, what wire and size. Its going to be run from the house to the garage so consider that it's going to be run about 75 feet or so.
I'm not experienced with high voltage wiring but I can do it.
The requirements on the motor call for,
240 volts
60 hz
phase 1
15 amps.

Quote Him,

Ok now that is the starting point here .,,


Do you have underground conduit { pipe } or just direct burial cable AKA UF { underground feeder } ?


If you have conduit what size you have there ?

If none there or just UF wire.

This what I will suggest is that you will have to add a subfeed breaker box in the garage get one with 6 space breaker box if you are not loading up the garage with tons of hevey duty tools like welder etc etc .,,

Before I can tell you the subpanel size what is your exsting house main breaker size is and is any empty two pole breaker slot that can be used ?

I want to make sure the basic question is answered first before we can go with correct route with the set up for safety and codewise.

Quote Me,

No conduit, I'll go the burial route..
Main breaker is 100amp
I have a 2 pole breaker already installed that wont be used, it was for a hot tub that I have removed. I can replace it if needed..

Quote him,

OK You can run #8-3 copper UF cable or 6-3 Al UF cable { both with ground conductor included }

That wire size i provided that is good for 40 amp circuit which it will be two pole 40 amp breaker.

Per the NEC code you will have to buried this wire at least 18 inch { metre } deep

And get subpanel box get one at least 6 space there are few diffrent size so watch it on that one and the reason why I say 6 space due the NEC code more like 6 throw is the max you can have without main breaker installed in the breaker box but if you going much bigger breaker box down the road the bet is off you will have to install the main breaker anyway.

And of course two ground rods as well at the same time when you pick up the breaker box you may want to get the ground bussbar kit as well some of them don't included in the kit they are only few bucks but it will save yourself alot of headache down the road

For the air compressor you can use 20 amp breaker I know you show the photo the motor is at 15 amp @240 v and use #12 NM wire [ remark the white wire as hot conductor so someone else don't get a mistake on this one ]

If this compressor do have cord and plug attachemnt let me know on this one

Quote Me,

No it doesn't have a cord, it's direct wire up..

Quote him,

Make it more clear on this one the XX-2 NM or UF cables if you have black and white.

Normally on 120 v circuit setup the black is hot conductor and white is used for netural conductor however.,, when you get on 240 volt circuits it will change a bit here the black conductor is still hot conductor but the white will become a hot conductor now that the reason why I mention to remark it to black or other colour marker { as long it is not grey or green you are fine } the reason so someone see that it will tell you that is not a netural connection at all and useally hot conductor on 240 volt circuit.

It will be easier to run the conduit { PVC pipe } for underground so that way in case you have to do something in future it will be much eaiser to do that instead of digging it twice.

You can run inch PVC conduit it will work fine for #8 THHN/THWN conductors at the same time you can if you want to add a inch PVC conduit for phone and data in the future.

Good luck, man. I bought a 110 so I wouldn't have to go through what you're dealing with. Plug and play, lol. What's the HP, max psi, capacity, scfm? Pics are kinda blurry. Love to hear about new toys.

Max psi is 135 lbs,
60 gallon tank,
10.2 scfm @ 90 psi
3.2 hp

Yeah I hear ya, I tried to avoid it too when I bought my first one but I fried the piece of shit. So I bought a new motor for it and it didn't have enough nuts to restart under load. So I go looking for a bigger one and found out that if you go any bigger then it goes to 220 anyway and them motors are $200 plus so I said f it and upgraded. I paid 300 for the first one and fried it in 3 yrs. This one will last a life time and it's one of my most used toys..So it's well worth it i believe..

Yeah, you sure did buy a workhorse! Nothing you won't be able to accomplish with that one. Good investment.
