I have a older spa which is wired outsdie from a 50 amp gfci box with 4
wire, black, red,white and green, The new Jucuzzi spa which i have not
gotten yet takes on 3 wires to operate. I down loaded the manuel but
unfortunately it dose not show what me what color they are. I spoke
with one of the service people at the spa place and he said i would
just have to not use the white wire, Just wondered it this sounded
correst here, I assumed that you only need one hot lead off the breaker
but it sounds like it uses both and just the ground instead of the
netual? Any ideas?
If everything is using 240V and not 120V you don't need the neutral.
You only need the neutral if something is using 120V. Assuming my guess is
correct you should be fine. On the other hand if I am guessing wrong it
could kill you. Make sure what you are doing after reading the installation
manual that should come with it. If you are not 100% sure, don't do it and
have someone who is do it.
I found the wiring diagram for jacuzzi today and it is a 240 vac (60)
dedicated with only the black red and ground use, so I do bleive that
the netual is not used or needed, but leadsme to the second question
does the netual wire from the breker need to be tied into the ground
bar in the box or is ok just being pigtailed to the netual wire comming
in the box from the maine service panel? And Thanks you guys are great
for the advice here

Neutral and ground should *never* be tied together except in the entrance
panel (where they must be). GFCIs have two neutrals, neither of which
should be connected to ground (except that ground and neutral are tied
together in the entrance panel). The output side neutral is never tied to
ground. The common neutrals in a panel should be connected to the neutral
bus and that bonded to ground (in the entrance panel only).
You are correct in your assumption and like Joseph said, it either doesn't
have any 120 volt circuits or it has an internal transformer to create them.
In either case you'll be fine just connect it to your GFCI without the
With the old tub, it had some items that ran on 120V and some on 240V.
But the newer tubs are being changed to 240V only. The simplest way to
resolve the issue is to tape off (with certified electrical tape) or
with a wirenut for the size of wire you are working with. NOTE: this
is at the hot tub.
Don't change any of the connections for the GFCI in the panel!! The
white pigtail from the breaker to the neutral bar is required for the
breaker to work properly. The white or neutral wire from the breaker
to the hot tub doesn't actually do anything. But there is no harm in
leaving it there.
