50ft wire run
- Thread starter [memphis]
- Start date
I would run at least 30 amp at 240v for future needs. it's not that much more to run a 10/3 or 8 /3 .

I was thinking that for my 240v welder. I'm not an electrician but I assume that would mean I should run another line if I want lights which would be on a separate circuit?

Maybe better to run a heavier wire, say 50 Amps to a small sub panel and have what you need.

Sub panel definitely appears the way to go... I could put a 60amp panel in quite easily instead of fishing two lines through conduit for 50 ft

No.
You can oly run a single feed to a detached building.
So you would want to run 8/3 out to the shed and install a small (6 space?) Panel. Circuit for lights, circuit for outlets (or 2) and a 240v circuit for a welder.

You may already know, but basically such as UF... #10Cu = 30A, #8Cu = 40A, #6Cu = 50A. Amps change with the use of conduit and THHN/THWN wire.

With a subpanel, you'll need two ground rods as well.

OP "I'll be burying in conduit "
I would take some pretty big conduit to run either a 10/3 or an 8/3
You're better off running individual conductors.

I'm not a code expert or electrician, so take my suggestion with a grain of salt.
I think you could run 8/3 wet rated wire for now (or maybe even 6/3), and wire it as a 20 amp MWBC with a GFCI on each circuit. This means there would be no subpanel, just a 3 wire circuit for the garage. As an MWBC, it would only provide two 120 volt circuits and there would be no 240 volt circuit.
I believe the MWBC meets code requirements for a single circuit feed to a detached building. The only catch is that with larger wire I'm not sure a GFCI or other initial 20 amp device could accomodate the 8 gauge wire.
Later on you could upgrade it to a subpanel and add ground rods and other items needed to be code compliant for a subpanel that has provides 120 volt and 240 volt circuits.
