just took my journeyman and got a few question i was iffy about. can someone help?

Hot tub install out side and what wiring method cannot be use?

1) uf " sunlight"
2) mc cable listed

I put down mc cable but was not sure.

transformer disconnect should be?3 answer

1) readily accessable
2)should be field mark on transformer location of disc if remote
3) if remote, able to lock in the open position
4)be in sight

I put down 2,3,4 artcicle 450.14. iffy because it doesn't say it has to be readily accessable but doesn't also say lock in the open position.

Well I would say 2, 3 and 4 without looking it up but if the disconnect had OCPD wouldn't it need to be readily accessible.

UF is not a listed wiring method for a tub or pool. You could use UF inside the building on a single family residence but to the outdoor tub you must use a method approved in 680.21
