O.K. Heres my problem. Previously, I had a 240 volt hot tub with a
50 amp Double pole GFCI. Recently replaced hottub with a 240v sauna.
Now, according to the wiring schematic. I need one 240v line hooked
up to power the three heating elements.
Unfortunately, the power coming off the GFCI seems to be on 110v ( 2
lines 110v each = 220v). This is a four wire hookup ( black, red,
white, ground). It seems that I need a 3 wire hookup for the sauna
( black, white, ground). However, no matter how I wire this sauna
heater, I seem to be only getting 110v to the elements.
Went to local hardware store and bought a 40 amp 120/240 v SINGLE pole
breaker was told that that the breaker should recognize whether the
appliance needs either 110v or 240 v and would give accordingly.
Unfortunately, when only hooking up, I still only receive 110 v to the
heater according to both my multimeter and a simple circuit tester.
Out of the 4 wire going to the sauna, I only hooked up black, white,
and ground, and just left the red dangling.
Am I missing something here? Is it possible to force 240v out of
single wire hookup? If so, how? Thanks.
Geez. Get someone who knows what they are doing before somebody gets
electrocuted!
Also check your insurance policy a) Home insurance; property and
personal liability, in case something catches fire or is not grounded
correctly. b) Personal life insurance in case you are not around!
Making a lot of assumptions; if the previous installation had a 50 amp
double pole breaker the previous (existing) wiring is adequate for the
new item?
Without seeing the hook up diagram hard to tell if the new unit needs
all three wires Red, black, white AND GROUND. Or it works with only
Red and black AND GROUND.
The hardware person either does not know waht they are talking about
or you misunderstood!
230 volt appliances (using typical North American domestic wiring) use
red and black PLUS GROUND and some case also need the white neutral
wire.
See paragraph one; get some help before you blow something inside the
new unit that operates on 115 volts by connecting it inadvertently to
230 volts.
We had to replace the electronic temperature control for a commercial
230 volt fryer and the thermostat unit smaller than a cigarette pack
cost a couple of hundred dollars.
It also may appear that you do not have the means or the knowledge how
to test (safely) for 230 volts?
Also btw in the case of sauna and spas etc. is it a code requirement
that metal plumbing etc. MUST BE BONDED to the electrical grounds? May
need to check codes in your jurisdiction.
