Running Power to Detached Garage

[knacker]

Hello.

I am going to be getting rid of our hot tub that came with the house and using that power for our new garage.

My question is, can I run the current 40amp service to a junction box attached to the house(since this wire is already ran to the outside) then run a wire from that junction box outside the house to the sub panel in the garage, or is it code to run a continuos wire from the main panel in the house to the sub panel in the garage?

Thank you.

Yes.

Yes to the first option, and the second option. As long as there is a junction box perfectly legal

Sorry. JB works, just don’t reduce your wire size.

Awesome! Thanks guys.

If the 40 amp breaker on the house panel providing the power to the garage is GFCI protected would I still need GFCI protected outlets and/or breakers in the garage sub panel, or would the entire garage be considered GFCI protected?

Thanks for the help.

i believe only the outside plugs need to be GFI rated.

but im sure someone will confirm this

If I recall correctly it doesn’t work to daisy-chain GFCI’s, one time I had done something to that effect and had to undo it immediately afterwards due to the upstream GFCI tripping. I would personally swap your GFCI at the panel for a normal breaker and then install GFCI outlets downstream as necessary. I'm sure some real electricians with better knowledge will be along to correct me as required .

When wiring GFCI outlets there is the option to just have the specific outlet protected, or to have it also protect anything downstream of it, depending on how you wire it. Wiring a GFCI to protect other outlets downstream of it and then wiring in another GFCI downstream of that one is a recipe for issues, this much I recall having learned the hard way.

As Caber said...best to change to a normal 2 pole 40 amp breaker and save or sell the 2 pole GFI . Not required by law though. The 2 pole would protect the whole garage and additional GFI protection would not be required. But a pain to have big garage tools operating off that main GFI.
