Does a detached garage with only one circuit need a subpanel? I can't find in the NEC where a subpanel is required.

It may be supplied by one, two, or three circuits if they're all from a single MWBC. So if you run one MWBC you're good. More circuits than a single MWBC would require a sub-panel. Take a look at 225.30.

Yes. I read that article. Didn't know if was addressed somewhere else. Thanks.It may be supplied by one, two, or three circuits if they're all from a single MWBC. So if you run one MWBC you're good. More circuits than a single MWBC would require a sub-panel. Take a look at 225.30.

That's it as far as I know. Was that the code section you were looking for or were you thinking that there may be something else?

Why would you need it elsewhere. There is 250.32(B) but that is really about grounding

12/2 with ground, 2 pole breaker in the panel. No ground rods.
If not that, then 1" PVC, 4 #8s, small panel and ground rods, 40 amp breaker

That implies 240v, no neutral.

He probably meant 12/3 with ground

It implies NM to me and that can't run to a detached garage. Unless it's UF or MC allowed for outdoors.

Need more info. How big of circuit, voltage, phase.
Is the one circuit feed from another building which has panel breaker and circuit go outside and into garage if yes then see post #2 code section above your warm welcome forum message something about disconnect. More important question disconnect would it be fused or non fused or breaker or without breaker
or
does garage itself and circuit feed from electric utility service in that case 230.71 I think.

If it's only one circuit why would that matter, are you thinking that the one circuit could be a feeder?

Yes it could be one circuit fed by feeder breaker in panelboard and located outside detached garage in another building.
