red = positive black or blue is negative and green and yellow = earth
In the USA, black is considered L1 (or load 1). Red is considered L2 (or load 2). White is considered neutral, and green is considered ground or earth.
White can sometimes carry the L1 or load, as in a return from a switch. Normally an electrician places an identifier on the white wire to note that it is carrying load.

∙ 12y agoIn a cord or flex for a small electrical appliance there is always a "Hot" or "Live wire, a "Neutral" wire and maybe also a "Ground" or "Earth" wire.
The "Hot" or "Live" wire is colored:
* Black in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Brown in Europe and other countries using a similar 50 Hz household AC
power system.
The "Neutral wire is colored:
* White in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Blue in Europe and other countries using a similar 50 Hz household AC power
system.
The "Grounding" or "Earth" wire is colored:
* Green in a cord or flex in the US, Canada and other countries using a similar 60 Hz household AC power system.
* Green and Yellow in Europe and other countries using a similar 50 Hz household AC power system.

Answer for USA, Canada and countries running a 60 Hz supply service.
If you are constructing an extension cord make sure that the ends go on the right end of the cable. Match the wire end when looking at it, to the proper pin configuration of the plug. Looking at the plug from the blade side directly on you should see a larger blade (silver) on the right, smaller (brass) blade on the left and a U shaped ground blade on the bottom. The white wire connects under the right (silver) coloured screw, the black wire connects under the left (brass) coloured screw and the green wire under the green ground screw. Looking at the end of the cable it should be matched to this configuration. If it doesn't, look at the other end of the cable. No wires should cross when connecting to the blades on the plug, if they do you have the wrong end of the cable.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

How do you know which wire is hot on a cord with no color system?
The National Electrical Code requires that the neutral wire is to be designated as the "identified" conductor. Method differ, but look for ridges, lines, or writing on one of the wires.
How can one tellwhich wires in the wall are from the power source and which are from the heater when both the wires are the same color?
Usually is 24volts AC so color code does not really apply.
110v electrical wire color code for construction site?
black
How many 10 AWG electrical wire in parallel to take 100 amp load?
The electrical code does not allow wires smaller that #2 to be paralleled to a connected load.
What color wires for 220v?
Telling the colour of wires has nothing to do with using a volt meter. Phase wire colours can be any colour except green and white. Usual 3 phase colours are red, black, blue. Single phase colours are usually red and black. Neutrals are always white and ground wires are always green or bare.
What is the electrical code for dropping so cord from bar joist?
Under electrical code 368.56(B), flexible cords and cables can be attached to building surfaces. However, under electrical code 400.8, flexible cords and cables are not permitted to be dropped from a bar joist.

Can two separate wires in parallel be used to increase the amperage capacity?
Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
Wire color code?
There are many reasons why wires have color codes. This is to ensure the right wire goes to the right place.

What did samuel morse's telegraph use to transmit messages?
The first electrical telegraphs used Morse Code, sent as long and short electrical impulses along wires.

What color wire code for ignition and starter wire?
Unfortunately, there isn't a single universal color code for wires in the car. Usually, the red wires power the vehicle, and the brown wires handle the starter.?æBefore anything else, however, make sure you have proof that you own the car. Hotwiring can get you in a buttload of trouble if you don't.
What are the wiring color codes for automotive vehicles?
Wiring color codes are the identification colors that color the wires in your automobile. For example, if you have a British car the blue, blue and white , and blue and red wires are for the headlights. The red and white wires are for the instrument lights, and the green and white and green and red wires are for the turn lights. The color code simply identifies what that wire does. Could you imagine if all of the wires were the same color. You couldn't identify anything in a harness.
