Full Answer

  1. Contact a local inspector

    Contact your local building inspector to ensure that your hot tub is up to code.

  2. Inspect the service panel

    Go to your service panel, and check that it is capable of handling the required amperage to operate your hot tub. Check that there are enough open slots to accommodate your hot tub wiring. Open the back cover of your hot tub to expose the electrical connection panel.

  3. Run the wiring

    Use a metal conduit or PVC to run the wiring from the hot tub to the service panel. Read the hot tub instructions manual to find out the gauge and number of wires needed. Ensure that all wires are buried underground for an outdoor hot tub.

  4. Connect the hot and neutral wires

    Connect the black and red wires to the ground and breaker respectively. These are the hot wires. Connect the neutral wires to the ground bar. Ensure that there is a provision for the double pole breaker and two adjacent slots before connecting the wires.

  5. Wire the disconnect box

    Consult the wiring diagram of your hot tub on how to wire the disconnect box. There should be a provision on your service panel to connect the “line in” to the disconnect box. Connect the “line out” from the disconnection box to the hot tub.

  6. Connect the hot tub wiring

    Consult your installation guide, and wire the hot and neutral wires from the hot tub control panel to the grounding and designated posts. These are color coded for easy and safe wiring.

  7. Recheck the connections

    Inspect all the connections before turning the hot tub on. Contact a licensed building inspector or electrician to inspect your work to ensure that the hot tub is safe to use.
