Have 200 amp breaker box in house, want to run electricy from there to shed. Shed needs lighting and outlets, including 220 for welder etc. Breaker box in shed is 100 amp. Planning on:
Putting 60 amp breker in house box
Running four #6 TWHN wires in 2" PVC conduit.

Does this make sense?

Not entirely.

2" is rather large for four #6's.
Also, you can run a #10 for the ground.
Having only 60A does not leave much room for things other than the welder. Is it a 50A stick/tig welder or a smaller mig?

Thanks for the answer. I know the conduit is large, but conduit's pretty cheap and it's only 40 feet. Gotcha on the #10 ground. As for the welder, this is purely speculative; I do not currently own one.

Why not pull #4's and have 100 Amp in the Garage. Labor is about the same, increased wire size is only additional cost, And Breaker.

That makes sense to me as well now that I think about it.

"Why not pull #4's and have 100 Amp"

Are you saying that #4's give 100 amp?

Are you saying that #4's give 100 amp?Some places still allow it.

Where I am #2AL SER cable is SOP for a 100A sub-panel.

#2 If aluminum, #4 if copper, and if you can afford copper #2, can only help reduce voltage drop.
We can only use copper down here, has been a supplement to the NEC for more than 30 years down here. Even when Dade County(Miami) allowed aluminum?
