ECN Forum Forums Thread Like Summary - Code Requirements for Detached Building/Garages

Hello,
I installed a 50amp dedicated receptacle for an EV charger in a detached garage. I did this by installing a circuit breaker within the home basement in the service panel and running the wire out.
The inspector doesn't like this and wants a 'handle-tie' on all circuit breakers within the basement to kill the power to the garage in one action.

For the future he says for detached buildings the ideal way when installing EV receptacles is the following.
1) Disconnect, terminate, &/or remove the old wiring out to the building.
2) Size correctly and run a new feeder fed into a sub-panel within the detached building.
3) Run branch circuits from dedicated circuit breakers from the sub-panel to all loads within the building (lights, receptacles, & the new EV receptacle).

I was initiallly going by 625.40(pg512) but now I also see 230.70(A)(1)(Pg89) which the inspector is going by, I think. He hasn't actually given me any code references on this. I have given him the code and he's agreed or not.

So what is the code specifically referencing multiple loads within a detached building?
I have the following references.

NEC2017 Code References:
210.11(C)(4)(pg60)
210.52(G)(1)(pg66)
230.70(A)(1)(Pg89)
240.24(pg98)(OCPD accessibility)
225.30(A)(7)(pg81)(EV Plugs)
625.40(pg512)(EV Plugs)

Thanks,
Phil

Thanks.

The local inspector is allowing a handle tie on both basement breakers going out to the garage.

In the future, we'll do one feeder into a subpanel.

Yes, I'm a master electrician in Minnesota, master of record for my company. But I've just moved here from 20+ years as a deep-sea marine engineer. So while I know electricity, I don't know NEC code (Art90-not applicable to ships), residential, nor new installations.

Yes, I have alot to learn. And I'm loving it <;
