Running Power to Detached Garage

[Pettrix]

Distance of current home to future home will be around 75-100 feet. Distance from future home to detached garage will be around 50 feet.

4/0 alum feeders for 200 amps is fine. 2 inch conduit. Need to run 2 power runs, 1 neutral run and a ground wire. 4 total wires. I use #2 alum for ground.

Out here, we use Ufer Grounds to ground the circuit panel. The ground wire gets tied into the rebar cage in the footing before the concrete pour. The copper ground wire then runs into the circuit panel.

Will a 100 sub panel be enough power in the garage for a 2 post car lift plus some LED lighting and 2 garage doors?

Plenty of power. Those lifts don’t take much power at all

I've got a 50amp 220v sub panel in my garage.
I run an arc welder, a 2hp swimming pool pump, air compressor, garage door opener, lights... all the modern conveniences.

I will go with a 2" PVC underground SCH40 conduit for my power wire that will go from the house to the garage. The power wire is being called out as a 3-#2 cu THHN 1-#6 GND

Is this the wire at HD?
Southwire (By-the-Foot) 3 Black Stranded CU SIMpull THHN Wire 24346999 - The Home Depot

That would easily fit in 1-1/4” conduit.

So, my shed, I ran 50 amp 220 with conduit and aluminum wire (yes, it was rated for the amps/distance). At the sub panel; I had a single 25 amp 220v outlet for my welder; and 2-110v circuits for outlets and led lights. Posts are at 8 ft OC, so I put a duplex receptacle at each post. Lights are 110v duplex outlets on roof rafters; but switched. Outlets are all higher then normally; ment to be 8" above "bar height"; and my work benches/stools are also bar height.

No permits pulled; and it's just a 24x36 shed; but I still did all 12 ga romex inside shed, and 8 ga (If I remember) for the very short, 10 ft run to the welder outlet.

I would make sure to make a least 1 110v outlet at your metal working station; probably a 4x4 box; I have to unplug the drill press or grinder to use a 3rd tool at the metal working station. Wood working station, same; table saw and chop saw; but got to unplug (or use extension cord) to use sander.

I do have the window unit ac on the closest 110v outlet to panel on 1 circuit and the air compressor on the closest outlet on other circuit.

I also ran a 3/4" cold only water service to the inside of the shed with an inside hose bib; makes watering dogs, washing hands; cooling hot metal parts, a breeze.

I like the SIMpull wire. It is much easier to pull in my opinion.

Good luck!
