In a 12-volt system, the red wire is typically the positive (+) wire, carrying the voltage from the power source to the device or component. It is important to ensure correct polarity when connecting wires to prevent damage to electronics or equipment.
A 240-volt circuit typically consists of two hot wires and a ground wire, with no neutral wire. The hot wires each carry 120 volts, while the ground wire is used for safety purposes. In a 240-volt circuit, the hot wires complete a loop by connecting to a load or device that requires the higher voltage to operate.
For a neutral wire on a 120 Volt three-phase four-wire system, you would typically use a white-colored wire. For a 277 Volt three-phase four-wire system, you would also use a white-colored wire for the neutral. White is the standard color for neutral wires in both systems according to NEC standards.
With thick wires that have excellent insulation.

Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
One is the 5 volt reference. One is ground and the other is the signal wire.

red and yellow
In the hot tub junction control box there should be three terminals. The terminal block might say line voltage. This is where the incoming "hot" wires connect. The red and black wires will probably be for the 240 volt pump motor and one of the two "hot" wires and the white wire will be used for the controls that control the pump.
It could if you don't get the terminals and motor wires on the correct terminals.
wire it in series
One way to join 12 volt 40 amp wires is with a wire nut cap. The wires are twisted together and then a protective cap is placed over them to ensure they stay joined.
