My city goes by NEC 2005. Few questions... but first what I am doing.
6/3 (3x #6s and a ground) romex from a sub panel in my garage (60amp breaker) above the garage (in the attic) and then outside, down about 5ft to my GFCI/disconect box. I plan to use metal conduit down to the box, it is 6-7ft away from the hot top. The hot tub already has a 6-7 foot pig tail, that is in a flexible PVC stuff. I plan to use a water tight connector on the end of it to go into the side of my disconnect box. I plan to mount the box about 48inches off the ground.
1) From what I understand the 5ft or so of vertical run down to the box, as long as I use sealed adapters(PVC with liquidtight, etc, or metal with a compression join) I can use the "indoor" type wiring. (per another thread on this site). Is this true? I don't seen any other way to transition from indoor to outdoor #6 wire, other wise i would need a huge 30cu-in junction box when the wire first leave the house about 10 feet off the ground to switch to outdoor wire for the remaining short 5ft down.
2)The box is designed as spa disconnect, and has a lockable cover. When standing at the box, i can see the entire access area for the pumps, and about 20% of the tub. Same goes from in the tub, if I was sitting in it I could only see the box directly if I was sitting in the back of it. From what I ready, this could be a "grey" area, but since the box can be locked during servicing it is probably ok. I am kind of forced to do this, or I will have to mount the box a LOT farther and run a LOT of conduit and wire! (hard to explain with out knowing how my lot is laid out).
3) I have a window that is 4.25ft away from the hot tub interior wall. I assume I will need to bond the window. What is the trick to doing that?
4)do i need a "clamp" entering the conduit that will run down from the attic wall, outside to the box?
5) see anything else wrong, or common mistakes people make?
Thanks!
