You cannot share that circuit

. For one thing, you wouldn’t be able to run the air conditioner and the hot tub at the same time, but the other thing is it could be dangerous. So you have to direct wire or home run, as it’s called, the circuit right from the hot tub into the main electric panel.

What gauge wire should I use for a hot tub?

Avoid using aluminum for hot tub wiring. Instead, use

size 6 AWG copper wire with

THHN (thermoplastic nylon) insulation. Use fish tape to pull the wires through the conduit from the fitting to the spa panel. As you pull the wires through the conduit, leave 6 inches of extra wire hanging from all ends.
