Hot tub is one of the important parts of hot tub installation and it has to be handled by an experienced and licensed electrician since dealing with water and electricity simultaneously can be quite dangerous for the layman. However, there are several DIY (Do-It-Yourself) enthusiasts, who carry out such tasks on their own just with the assistance of proper guidelines. Such people can always find some basic instructions such as then electrical needs of the hot tub right in their owner’s manual. So, this general guide on hot tub wiring can walk you through the procedure if you wish to install your hot tub.
Consult a Local Building Inspector
Before starting the work, it is essential to consult a local inspector since the new hot tubs need to comply with the regulations. Few municipalities may require a certified electrician to do the hot tub wiring. However, few others just need a permit to be taken or someone has to check the project before beginning.
Check the Service Panel
Ensure that the service panel has adequate capacity for the amperage needs and open slots to house the power needs of your hot tub. You should also get the electrical connection panel checked. You can find this at the rear cover fastened outside the unit.
Run the Wires
Run the wires from the service panel to the hot tub through a metal conduit or PVC. The gauge of the wire and number of wires needed will be mentioned in your hot tub’s owner’s manual. If the wires need to be run within the house, it can be directed through the crawl space or basement.
If it can be run outside, it should be buried under the ground, particularly if the hot tub is over a few feet away from the home.
Look for the Necessary Slots
Check for the needed two nearby slots in the panel for installing the double pole breaker. The black and red wires, which are known as hot wires, are the link to the ground and the breaker, while the neutral wires should be linked to the ground bar.
Check the Line
Ensure that the line coming from the service panel will link to the ‘line-in’ connections marked on the disconnect box. One more line will link the ‘line-out’ connection moving towards the tub. Based on the make and model of your hot tub, a wiring diagram will be given on wiring your disconnect box.
