Everyone makes good points about the ability to use “smaller” wire sizes when running 240v. That is true, but for the small difference in wire prices consider running 10-3 inside your shop.

Here is what I used from HD. The best part of this is that it is an “armored cable” so you do not need to run conduit. NOTE—This is NOT a burial type cable. Interior only.

AFC Cable Systems 125 ft. 10/3 Gauge BX/AC-90 Cable
Model # 1408N32-00
Internet # 202286692
Store SKU # 282805
$136.00 /EA-Each

FOR BURIAL USE TO THE SHOP:
I do not know how far you need to run service. That will dictate how large a cable to use. You will need to find out the requirements for the distance you will be installing.

FWIW, running service to my garage (100amp service) I ran #00 twisted wire w/ground overhead. That was overkill on my part, so check locally for what you need to be looking at.

IF #10 is adequate for your service to your free standing shop/garage:

Southwire 250 ft. 10-2 UF-B W/G Cable
Model # 13056755
Internet # 202316282
Store SKU # 269077
$224.00 /EA-Each

It can also be used for outbuildings such as garages and barns. UF-B feeds from a distribution point in an existing building. UF-B has a heat capacity of 90* C and is rated at 600 volts. UL Listed and CSA Certified.
