I am giving you my version of what the neutral wire does in your main electrical panel in your house going back to the transformer. That way the exposed disconnect is relatively inexpensive if it ever needs replacement.

What does the neutral wire do. The bare wire is called the ground wire. What to do with the neutral. That is for simple single panel installations. So the question is. If you cant find the source of a problem. I prefer the gfci indoors to keep it out of the weather.
The neutral is an insulated wire because it is part of the circuit which flows electrical current. Follow standard color codes that identify each wires function in a circuit. I might not actually need a 4 wire tbd but it seems silly not to just have it and future proof. This knowledge can help you pinpoint problems and connect wires to the correct terminals when making repairs. Neutral is usually connected to ground earth at the main electrical panel street drop or meter and also at the final step down transformer of the supply. All home electrical wires made in the us.
The neutral wire is a return wire for the current in an electrical circuit. When you open an outlet it can be useful to figure out the position of the outlet or switch in the circuit as well as the function of each wire. Neutral is a circuit conductor that normally completes the circuit back to the source. Like the neutral wire the ground wire is also connected to an earth ground. Most if not all disconnects i can find either for spas or air conditioners are 2 pole. Here i talk about the neutral wire in residential electric.
However the neutral and ground wires serve two distinct purposes. The neutral wire is connected to an earth ground. 4 wire from subpanel to exterior disconnect 2 hots neutral ground 4 wire from exterior disconnect to hot tub. The neutral wire the purpose of the neutral wire is to complete the 120volt ac circuit by providing the path back to the electrical panel where the neutral wire is connected and bonded to the earth ground. Do not confuse for the ground wire which is also a return wire but is used in the event the connected appliance shorts. Knowing which wire does what and goes where is imperative not only in the correct configuration of an electrical system but also for your familys safety.
For multiple panels the situation is more complex. The grounded electrode conductor.
