Servuce for Morton Steel Building

I have just completed construction on a 42x52x13 steel building and I am preparing to install electrical service. I plan to have a wood shop using various power tools, compressors, maybe a basic welder. There are also 2 12ft overhead doors with power operators. Any recommendations as far as 100A, 125A and what kind of load center to install.

Thanks

Thumbs up

The best system for your type of structure and electrical-load requirements is a 3-phase, 4-wire system.

The implication is that you must contact the utility co. to determine if they will provide you with this type of system at the location.

After this specific issue is adressed, the next step is to determine the Service ampacity based on the type of system available.

Good Luck & Enjoy the Experience!!!!!!!

Where I am only commeracial con get 3 phase power. That may not even be an option if this a home situation.

I would go with 200 amp. The cost difference is minimal on a new install.

What joed said.

The decision to go three phase should be determined by the demand load and the type size & quantity of tools. If you will have alot of 5+hp motors then 3ph may not be a bad idea since you can run much smaller conductors and receptacles, all for the addition of one extra hot wire. Also bigger motors are easier to get in three phase.

If this is a residential location then basically forget three phase. In most residential areas it is not allowed/available. Then again if it is residential then I assume you won't have too many 10hp sanders and moulding machines.
