120v hot tub wiring
I was wondering if anyone was familiar with hot tub wiring. It is a Morgan Spa and the wiring scheme advises that it is a 120v (3 wire) cord connected to a 20 amp breaker. There is an option to convert it to a 240v cord as well.
My questions is this: Can I run the 3 wire 120v to a single 20 amp breaker on the main panel or do I need to get a double 20 amp breaker? I have an older home and an older panel if that makes a difference. I know there might be several variables, but if I could get some direction, I would appreciate the help. Thanks in advance!

First off if it has a heater it will probably work better on 240 volts. Usually on 120 volts the heater and pump can't be on at the same time, too much current draw. Regardless of whether 120v or 240v since it is outside it will need to be wired with conduit and individual wires.The outside portion of the wiring can not be wired with cable because an insulated ground must be used. Any portion of the wiring in the house can be cable but must transition to individual wires in conduit as it leaves the house.
Tell us your final decision on voltage and we can go from. If 240v tell us the full load amps. Either voltage we need to need to know the distance from the breaker panel.

The spa will be outside and it will be hard wired, not run to an outlet.
