Dedicated Circuit
 
I'm installing a whirlpool type tub that requires two 15a GFCI protected circuits. One for the pump and one for the heater. I want to use blank faced GFCI outlet that will be located in an adjacent closet.
-Can both of these circuits enter a common 2 gang outlet box and get wired to a split receptacle since both circuits are running to the same location if all wires are kept separate besides the ground?
-Is there a problem in running electrical cable past plumbing lines?

Thanks

You will need separate GFCIs for each circuit.

Yes I plan on using two two blank faced GFCI's. Can they be mounted in a two gang box, same thing with the outlet box?

To answer the OP, YES!

You can mount both blank-faced GFCI units in a 2-gang box, and then feed a split-wired outlet under the tub.

Be sure to remove both interconnection tabs on the split-wired outlet.

OK Thanks.
So no problem with plumbing lines and electrical cable?

If you do this you will need to bring 2 two wire cables to the plug and break off each side of the plug. If you run a 3 wire you will have nuiance tripping of the GFI.

I'd use a 4-wire cable. Do that have that available in Canada?

As long as you don't install the wires inside of those plumbing pipes, you should be good to go.

I was planning on running two 14-2 cables but if I can run just one cable from the breaker box it makes it a lot easier.

You can use a 14/3 from the panel to the GFCI as long as you pigtail the neutral at them. From the GFI you will need two 14/2 to the plug. I have never seen 4 wire lomex but you can get 4 wire BX, if you get 4 wire BX techincally you would have to derate because you have more then 3 current carrying conductors. So for a 15A breaker you would have to use 12/4.

The easiest way to do this is, run 2 separate 14/2 , always a good
Idea not to share neutral when running two motors, put the GFI's at the panel (easy to reset if GFI trips) then run your individual 14/2 to regular plugs near your tub or wherever u were going to put them. Keeping the motors separate, by running 2-14/2's is good if there's ever a problem with either the pump or heater, easy to figure out which is having trouble if it was to have own feed

I have to agree with brric depending on the draw of the tub and the heater I would have a seperate GFI for each one and each would be a 20 amp line right under the tub with an accessible door.

It seems that all faceless GFCI's are rated at 20 amp. Is that OK on a 15 amp circuit?

Specs say :

General Information
GFCI ratings:
15A-125V AC - Cat No. 7599 Duplex
Receptacle
20A-125V AC - Cat. No. 7590 Faceless
20A-125V AC - Cat. No. 7899 Duplex
Receptacle
All devices rated 20A feed-through

No problem.
