You should never trust any wiring without using a tester (get one at hardware or home improvement store. ) in USA, White/grey/bare wire is neutral, colored wire is hot (live). In a pure 240v connection, there are two hot wires and no neutral wire. Sometimes they still use black and white for this. If you are seeing black and red wires you might be looking at a split phase panel -- you'd best check that out
No, the black wire is typically associated with line 2 in a 240V line. In a 240V circuit, there are two hot wires - line 1 (black) and line 2 (red), as well as a ground wire and sometimes a neutral wire.
No, it does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
This is not a cut and dry answer as it depends on the application. 240v only needs two wires to operate with a green (ground) for safety. Single phase (residential) 240 wires are generally black and red (or a red tracer), but the National Electric Code does not stipulate the colors (as long as they are not green or white). Three phase colors are generally black, red, and blue and also require a green ground (as does EVERY electrical application). The white wire is a grounded conductor. It is only used in 110v applications. For 240v home appliances such as ranges or dryers, 110v is required for the controls so the cable would contain a green (or bare) ground, a white (for the 110v, and a black and red for the 240v. Things like water heaters that don't require control voltage don't need the white wire. Pinky
The shield wire is not the neutral wire. You will need to connect the black and red wires to the hot terminals of the stove plug and the shield wire to the ground terminal. However, it is advisable to consult a licensed electrician to ensure proper and safe installation.
The whites are Neutrals or Grounds and the Red and Black are each 120v. One white and either the black or red for 120v and one white, both the red and black for 240v.

first of all you buy a double pole unit thermostat which should come with the mounting plate and thermostat and it should have 4 wires 2 red 2 black okay now you join the red to the red power wire and black to the black power wire and the 2 remaining wires which should be a red and black can be joined to the red and black wires on your heater .....now you should be good to go ............LEE48

The standard color coding for electrical wires in a circuit is red for live or hot wires, black for neutral wires, and white for ground wires.
Red= 12v Hot & Black is ground.
red is positive and black is neutral...if the wires are red and black.
The correct order for connecting the red, black, and white wires in an electrical circuit is typically red to black to white.
The best way to connect the black and red wires when setting up a new electrical circuit is to use wire nuts or terminal blocks to securely join the wires together. It is important to ensure that the connections are tight and properly insulated to prevent any electrical hazards.
The correct order of connecting the red, white, black, and green wires in a circuit is typically red to black, white to green.
