2. The power supplied to this hot tub must be a dedicated circuit with no
other appliances or lights sharing the power provided by the circuit.

aluminum wire.
• When using wire larger than #6, add a junction box near the hot tub
and reduce to short lengths of #6 wire to connect to the hot tub.

or circuit breaker to open all ungrounded supply conductors to comply
