Electrical Scorching Tub Set Up
Very hot tubs arrive in numerous measurements ranging from the adorable, two particular person "Soft Tub" to the quite large many particular person get together units.
120 Volt Units
Some of the small tubs have a 120V 20A energy requirement, which indicates that you can just plug them in to a useful receptacle. I have even noticed significant tubs set up for 120V power offer. When this is done it normally requires permanently for the tub to warm up due to very tiny sum of power flowing by way of the heating aspects, I do not recommend this way of installation for the large models.
A notice of caution here is that the tub will eat most of the circuit ability so that if you use some thing with appreciable draw (hair dryer, microwave or other appliance or electrical resources) the circuit breaker can be tripped. This is why it is very best to run a separate circuit for the scorching tub no make a difference what dimensions it is.
240 Volt Units
Allow us commence with the two fixed placements.
one) In which is the electric company panel? Ideally the primary panel given that we will be pulling about 50 Amps of 240 Volt energy. It is typically positioned near a front corner of the home.
2) In which is the scorching tub positioned? Most times this will be found in again of the residence.
Energy to the Very hot Tub
1) Exactly where is the scorching tub? Is it on a deck related to the property or on the ground?
2) Is the home on a slab or is there entry beneath the property?
Residence and Hot Tub on slab
Allow us start off with the residence and the hot tub on a slab. This circumstance tells us that we will need to run the whole power supply line in 1" Timetable forty PVC conduit in the ground 18 - 24 inches deep based on jurisdiction. Previously mentioned ground it has to be in Routine eighty PVC.
We run the conduit from the principal panel down into the ground to the again of the house where we come out of the ground and enter the GFCI disconnect/Spa Pack.
Notice: the over is for a surface mounted panel, if yours is flush mounted (or in the wall) then you will will need to use two 45 diploma sweeps to get into the bottom of the panel. This is fairly effortlessly doable, and chalking fills in any excessive opening designed in the course of the set up procedure.
The power to the scorching tub is needed to be Ground Fault Circuit Interrupter protected (NEC 680.22 -A5). This GFCI protection panel (Spa Pack) is to be not nearer than five feet from the scorching tub, but in website of the unit no gates or walls (NEC 680.24 -B2b).
The conduit then runs again into the ground and out to the very hot tub where it re-emerges from the ground. The energy feed into the very hot tub is usually on the left aspect of the unit facing the detachable access panel. Some units have developed in PVC flex conduit foremost to the electrical power panel. If your unit does not have the flex by now set up then you will need to install some 1" PVC Flex.
Wire variety
Now comes the fun aspect, pulling in the power wire. Most of the huge units require fifty Amps of 240 Volt energy. To provide that we will want #six THHN stranded copper wire. You will want 4 (4) items for each of two runs. From the main panel to GFCI then GFCI to very hot tub. Be extremely careful to measure precisely, Measure from the inside of leading of the principal panel to the trench bottom, the length of the trench, then up into the Spa Pack as well as 6 (6) inches. Up coming is Spa Pack to scorching tub. It is often better to have an added two feet of wire that you don't use than currently being four inches as well quick.
The 4 runs of wire are:
120 V -- Black
120 V -- Red
Neutral -- White
Ground -- Green
The colors are for identification, I do not get #six in all of the hues, I use colored coding tape to mark about two feet of each conclude of the wires. Inside of the very hot tub handle panel they are quite excellent about identifying wherever every wire goes. It is also time to start filling the hot tub. Now again to the Spa Pack, the red, white and black wires attach to the bottom of the GFCI breaker with the green on the ground lug or bar. The wires from the panel attach to the ground bar (green) neutral bar (white) and the breaker feed lugs (black and red).
We are almost there, now back again to the principal panel and set up a two pole fifty amp breaker (2P50) that is developed for your panel, connect the white and green wires to the neutral/ground bar and the red and black to the breaker. When the tub is complete of drinking water then you can flip on the major breaker, the GFCI breaker and begin the scorching tub from its operating panel. It will take a few hours to heat up. It is enjoyable to check out all of the jets and other attributes of the tub.
Small 120 Volt tubs
If you are supplying a little tub that only calls for a twenty Amp 120 Volt circuit then you use half or 3 quarter inch PVC conduit and 3 #12 gage wires, black, white and green. You can also use a regular GFCI receptacle mounted on the side of the property or post inside the reach of the scorching tub attachment cord.
Raised homes and decks
If you have access below your house and the tub is on a deck you can remove a good deal of digging by just working the conduit beneath the home and deck. You follow the very same procedure as over only no digging. If there is no flex conduit already put in, I arrive into the company part immediately from the bottom of the deck. Employing a 1" ninety diploma sweep I decide exactly where I will drill my entry hole, from inside, via the base of the scorching tub and connect to the power feed conduit from the GFCI/Spa Pack below the deck. I also do not glue this final sweep right up until I have pulled in the power supply wires. That makes for an less difficult pull with less 90's to pull by way of.
Now it is time to take pleasure in your perform, you did great, celebrate in your new hot tub.
