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

When connecting a 240V line with two hot wires and a ground does it make a difference if the red or black hot wires are connected to L1 or L2 for a jet pump pressure switch?
No, it makes no difference. The selection of red and black "hot" wires on your 220 line is arbitrary.
How do you wire a 240V stove plug if old stove was hard wired and had 4 wires Black red white and ground coming from the wall are three wires Black red and a shield wire is the shield wire the neutral?
Shield is ground. White is Neutral, center tap of the transformer from the power company.
How do you hook up a 3 wire water herter to 4 wire circut?
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.
Does the 230-240 volt circuit consist of 3 wires 2 black and 1 white?
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
What polarities red wires and black wires indicates in case of dc measurement?
In typical DC circuits, Red = Positive, Black = Negative.
How do you hook the 4 wires which are 2 whites 1 red and 1 black coming from the back of a generator to an outlet for 120v and 240v?
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.

How do you fix an electric baseboard heater?
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
What colours are the speaker wires on a 1998 Renault Megan to determine negative and positive?
red is positive and black is neutral...if the wires are red and black.

What are the black and red wires on angel eyes?
Red= 12v Hot & Black is ground.
How do you bypass a wattage limiter in a ceiling fan?
just did one. Cut the three wires and remove it. Then join the black to the red and the white to the white. Thats all it takes
Have a red white black wires for a dryer plug what wires are hot ones?
Should be 220 to 240 V between Red and Black and 1110 to 120 V between Red and White and between Black and White.
Are there only 7 plug wires on your motor?
