talked to my wiring guy. Finally

[bucs012]

Ok, they are going to break ground on my 50x30 Friday.

I had the wiring guy over, yesterday. He is charging me $5 per foot to bury and run the 110 from the junction box into the garage. About 100-130 feet.
$200 for a breaker box that I believe he said would have 22 slots? Also he checked with our electrical co and they will supply a meter (just for the garage) for $8.50 per month. Same charge for kilawatts as the house at 8 cents, I believe is what they said?

Question- Will 110 be large enough to run 20 amp recepticals on? It sounded like he planned to set my 20 amp recepticals on their own breakers so we really do not need to run 220? Does that sound right? He is getting me a larger breaker box in order to run thing on their own breaker and not have a lot of things running on any single breaker in the box so that we can stay with 110. I do not have any plans for large lifts or major welders. Mainly just a table saw and normal average garage things.

The "wiring guy" should have been clearer than mud here. Do we understand this correctly , he plans on running 120Volt service?

Your plans will most likely change, and you'll regret not running 220V. Might as well run it while you're at it.

Run 220v, 100Amp service as a minimum to your detached garage. 50x30 is pretty big, I would have a 220v, 220amp service out there if it was me. Table saw, air compressors, welders pretty much are 220v tools.

You need 220 100A minimum in a building that size. Also, beware the second meter. We used to feed the shop separately because a pole sits right across the alley. Then I figured out that the electric provider treated the second meter as a "commercial" meter. This is in Texas and the PUC allows it, because "houses don;t have two meters". OK then. You may get charged the same RATE but charges might be based on peak usage. Check your state regs before you commit to a second meter.

My lazy azz would dig a hell of a ditch for $650

 

[bucs012]

Please help me understand. What is the difference between 220v run with
100 amp or 200 amp?

 

[bucs012]

How about a site that I can go to and read more about terms and that will explain, 110 and 220volts and amps? Anyone know of a great learning site on the net?

Thanks.

If you plan on working in this building I would certainly run 240v service to the building. Most reasonable sized air compressors and welders are 240v among other things.

It's hard to say what you need for amperage. My folks have 100 amp to their house and that powers the house, my Dad's shop, a lean to off the shop and another 2 car garage just fine.

this 'wiring guy', is he a licensed electrican (if your state has licensing)?

the whole 110 thing seems odd, but he may very well be installing a single phase 3 wire 120/240 service and is just referring to it as 110. The power company isnt going to let you have 100 amps of 120v anyways. Just make sure everything is spelled out properly in your contract.

Either you misunderstood your wiring guy or he's an idiot. No one runs a 110volt feeder 130' into a 22 space panel. Who the hell needs 22 spaces for 110 only??

The fact you call him a wiring guy instead of an electrician makes me think he's probably a hack anyways....

This is a no brainer
