The one you don't want to touch.
the hot wire carries the electrical voltage
The hot screw on a Porcelain socket or and electrical is the Gold screw. The Silver screw is the neutral
because you are switch the hot leg, so it can be turn on an off.
Light in night, cooling in hot days, ice making, computer, running business units etc.
In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.
It is the ground line of the system or electrical leg that is going to the earth.
Hot Leg was created in 2008.
A phase leg connects to the neutral through the connected load.

"How do you unhook a hot tub that was connected to an '''outside electrical outlet?'''" .... Just unplug it
Most home electrical hot water tanks will hold 40 gallons.
Red is the alternate hot leg in a 2 way switch circuit
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
Sorry, but it is impossible to get 220v (240) from one leg, it has to be two legs as each leg is 120v.
You don't provide enough information to be certain what you are measuring. If you have a hot leg then by definition you will have a voltage between the hot leg and ground or neutral (if neutral bonded properly to ground in main panel). However, there may be no voltage between hot and some unspecified "floating" wire.
Electrical heating element, electrical blower - blows hot air.
