How To Wire A Hot Tub
Learning how to wire a hot tub can give new life to that old, cold, drafty hot tub. Wiring a hot tub is fairly easy to do but it requires basic knowledge of how electricity works, knowing where your power source is, and of course a little patience. If you think you’re ready to tackle the task of wiring a hot tub, ten take a look at the following list of items that you’ll need to heat-up that chilly hot tub.
To wire a hot tub, you’ll need the following:
- Working power source
- Voltage tester
- Wiring/marine wiring
- Electrical tape
- Electrical knife
- Water sealer
- Run your wires. The first step to wiring your hot tub begins with finding the wires that you will use to power your hot tub. To find these wires, either run wires from your breaker box or use an old set of wires that are no longer used. Use a voltage tester to make sure that the wires that you’re using will hold enough voltage to adequately power your hot tub. Consult your hot tub’s manual to make sure that the voltage held by these wires will be enough. If not, you should consider running a new set of wires from your power source.
- Install your wiring. Once you’ve tackled the task of getting wires to your hot tub, begin running wires to the locations in your hot tub that require a power source. These can be places like lights, jets, and the hot tub’s heater. Use an electrical knife to cut the tubing off the tips of your wires and wrap the copper ends around the locations that require power. Do not work with live wires during this part of your project or any step until you are completely done. For the wires in your hot tub, use marine wiring; it’s specifically built to work in locations with moisture and water.
- Splice your wires. After you’ve run your wires from the locations in your hot tub, connect both sets of wires (hot tub and power source.) To do this, splice the ends of your wiring using an electrical knife. Use caution in doing this step by making sure not to accidentally cut your copper ends. If you cut a copper end by accident, cut about two inches of wiring off the end and begin the splicing process again. After each of your ends have been spliced, connect the copper ends to each other by wrapping them around each other. Use electrical tape to seal-up the connections between the wires to prevent a fire hazard.
Once you’ve completed these steps, it’s safe to turn on your electricity and check to see how your hot tub works with your new wiring. If at any point in this project you need to drill into the base of your hot tub to reach areas that needed to be wired, use a popular water sealer to seal-up these locations. Give these areas adequate time to dry before attempting to fill your hot tub with water and use it. If you run into any issues with any of your wires not working, use your voltage tester to test each wire. Sometimes, wires are easily nicked during the installation process and may need to be re-installed. Make sure to enjoy your new hot tub and the fact that you did it yourself!
