![]() ![]() ![]() So my question is can I go through the sub panel or do I need to wire directly to the main panel.Unfortunately the main panel is not very accessible to run new wiring so I would like to run the 6-3 from my sub panel to the hot tub disconnect.My home has a 100 AMP sub panel feeding off the main.Electrical Question: Hello Dave, I am installing a hot tub that calls for 50AMP service. It doesn't necessarily mean he has to connect up the third element but does raise yet another question.Panel Options for a 50 AMP Hot Tub 220 Volt Circuit One last point the OP's mention of a third, possibly unconnected element may raise the possibility of three phase? That makes it sound like a fairly 'heavy' unit. However if it did consume the full 50 amps, which is doubtful, at full blast that could be an electricity cost of $1.50 per hour? If it's only small sauna unit a 50 amp beaker may be too big? Fifty amps at 230 is 11.5 kilowatts. On other hand each element may be for 115 volt and it may be 'possible' to connected them for 230 volts by wiring them in series.Įven if the OP was to quote the model number or scan the connection diagram and post it somewhere we are still, by replying, assuming the info is correct. Recommend being careful about giving advice such cases.įor example the heaters elements MAY be for 230 volts 'each'. ![]() " situations without the person really understanding what's going on. It's one of these "The red goes here and the black goes there. Tony: This guy/gal doesn't understand enough to parallel or series connect the heater elements as required. MUST BE BONDED to the electrical grounds? May need to check codes in your jurisdiction. is it a code requirement that metal plumbing etc. It also may appear that you do not have the means or the knowledge how to test (safely) for 230 volts?Īlso btw in the case of sauna and spas etc. ![]() We had to replace the electronic temperature control for a commercialĢ30 volt fryer and the thermostat unit smaller than a cigarette pack cost a couple of hundred dollars. See paragraph one get some help before you blow something inside the new unit that operates on 115 volts by connecting it inadvertently to The hardware person either does not know waht they are talking about or you misunderstood!Ģ30 volt appliances (using typical North American domestic wiring) use red and black PLUS GROUND and some case also need the white neutral wire. Or it works with only Red and black AND GROUND. Without seeing the hook up diagram hard to tell if the new unit needs all three wires Red, black, white AND GROUND. 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? b) Personal life insurance in case you are not around! 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. Out of the 4 wire going to the sauna, I only hooked up black, white, and ground, and just left the red dangling.Īm I missing something here? Is it possible to force 240v out of single wire hookup? If so, how? Thanks. Unfortunately, when only hooking up, I still only receive 110 v to the heater according to both my multimeter and a simple circuit tester. 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. However, no matter how I wire this sauna heater, I seem to be only getting 110v to the elements. It seems that I need a 3 wire hookup for the sauna ( black, white, ground). This is a four wire hookup ( black, red, white, ground). Unfortunately, the power coming off the GFCI seems to be on 110v ( 2 lines 110v each = 220v). I need one 240v line hooked up to power the three heating elements. Recently replaced hottub with a 240v sauna. Previously, I had a 240 volt hot tub with aĥ0 amp Double pole GFCI. ![]()
