Spa disconnect / GFI confusion among other things
 
:wink:Hello,
I can't seem to get a consistent answer to this question just surfing web.
DO I or DO I NOT need a manual disconnect / cutoff no closer than 5 feet and within line of sight ?
Everything seems to conflict.
I will have a dedicated sub panel somewhere close to spa with a GFI 60 amp breaker.
Some places say that IS the disconnect.
Some places say I need the disconnect AND the GFI breaker. So confusing.
I think NEC says disconnect doesn't apply to single family dwellings.
Please help.

Also, a couple easy questions.

1) Does sub panel have to be mounted a certain height or distance from ground / roof ?

2) Spa requires 6 AWG which is what I was planning to use. What size ground should I use ? 6 AWG or maybe #8 or #10 ?

3) Code says I cannot have an outlet within 10 feet of spa. Can I just replace cover with a plate / blank or do I have to physically unhook power supply ?

4) I will be installing an outlet in my BBQ island. I plan to use UF for the 15 feet it needs to go underground. I was told I can continue to use the UF
inside the island as long as I stapled it to the structure and didn't just leave it laying on ground.
Is that correct ?

5) Does outside outlet need to be a GFI outlet or will a standard out be ok ?

6) I was planning to use a 12/2 regarding the island. 12/2 and a 20 amp breaker ok ?

Thank you very much in advance.
Much appreciated.

You do need a disconnecting means.

You are confusing a disconnect with an emergency stop switch (Panic button). You do not need the panic stop button at a single dwelling. You still need a disconnecting means. The GFI breaker can serve as the required disconnect if located within sight as mentioned earlier.

Also, a couple easy questions.

1) Does sub panel have to be mounted a certain height or distance from ground / roof ?

I prefer to mount it a couple feet off the ground, to prevent water splashing in during heavy rains.

2) Spa requires 6 AWG which is what I was planning to use. What size ground should I use ? 6 AWG or maybe #8 or #10 ?

If specified by the manufacturer, then follow their instructions. If not specified, then a #10 ground is all that is required.

3) Code says I cannot have an outlet within 10 feet of spa. Can I just replace cover with a plate / blank or do I have to physically unhook power supply ?

Blank off any non-conforming outlets. Just wire-nut the conductors to maintain continuity of the circuit.

4) I will be installing an outlet in my BBQ island. I plan to use UF for the 15 feet it needs to go underground. I was told I can continue to use the UF
inside the island as long as I stapled it to the structure and didn't just leave it laying on ground.

Correct.

5) Does outside outlet need to be a GFI outlet or will a standard out be ok ?

GFI protection is required. Whether this is done by a GFI breaker, or the actual receptacle is up to you.

6) I was planning to use a 12/2 regarding the island. 12/2 and a 20 amp breaker ok ?

Sounds like a plan.

Thank you very much in advance.
Much appreciated.

This is not true according to the NEC. The code states you cannot have any receptacle within 6' of the spa/hot tub and you MUST have a GFI protected recept outside of 6' and within 10' of the inside wall of the tub.
