Electrical service on new potential shop

[keith5064]

Finally decided I need to upgrade from a single car garage to a larger shop, looked at one in my area yesterday, and was curious what you guys think about this electrical? I will be using a 220v welder and 220v 80 gallon air compressor for the largest
equipment..

Is that something you are buying/renting? looks like someone changed the panel out, but has # 10's feeding it (maybe its temporary?) the service wires do not match the capability of the panel, they are undersized. Looks like # 10's feeding a 200 amp panel.

I looked at the wires and the say #8 tw , not sure what tw stands for though?

They could be #8's. Thats ok to feed a 200a panel as long as the panel capacity isn't exceeded. You need to look at the breaker in the main panel and it needs to be matched to the wire.
Bottom line is you need to bring in a larger wire on an appropriate sized breaker for your wants.

To me 8 gauge is not enough to support 200a, and with the 100a and 60a outside is just kind of confusing too me,Also its something I'm thinking about buying, I have one more place to check out, there's really a shortage in decent buildings around here..

What size breaker feeding it? Weird, setup, what did they do in their before, I seen a building where they had a 200a 40 space panel with all 15 a mini's in it, so A LOT of breakers. Being fed by a 30a breaker with 10 ga wire. It was a "clean" power circuit that ran all the printer and computers at each station in the building. They didn't need a lot of power, just wanted each one on its own breaker so they could shut them down individually, there had to be 30K feet of 14/2 in that building...


Either way it looks like there is a nice big conduit running to it so you can run what ever you want to that panel, depending where it is coming from...

It was an old gas station years and years ago.. The 60a and 100a is what's feeding the main panel..

FWIW the 60 amp breaker is in the tripped position. You have already stated more load than what the wires feeding the panel can carry. Since it appears that this is a sub panel, it needs 4 wires feeding it, and seperate the neutrals and grounds

Yeah I noticed that as well, i think I'll have an electrician check it out before I make any decisions..

You are confused by the 200a panel. It is like putting V rated tires on a Yugo.
What is the breaker before the wire? Those are the important ones and should match.

If the 60 or the 100 is feeding this panel, the wire is to small. Talk about the issues with the owner, talk about possible wiring violations, his insurance company wouldnt be to happy!! maybe he will fix everything. If you are purchasing the building, see if you can buy it "As Is" and drop the price for repairs

8 TW is 40A rated, wire with TW insulation is pretty much unheard of anymore.

 

[keith5064]

Had an electrician check it out.. Said basically what needs to happen is too add larger wire ... And I forgot the rest of the technical items..bout $500-$1000 he said...

You should mark that nuetral white so it doesn't get mixed up in the future. I'm also curious as to why the breaker is tripped

 

[keith5064]

There was another little building off to the side and I believe that was supplying power at one time, but that building has been recently torn down..the 100 amp breaker is what goes to the panel I showed....which when I looked at this building I specifically looked at the service..just to make sure things are up to snuff..the owner now knew nothing of this till I brought it too his attention...

Wow 100a breaker feeding 40a wire...
