Follow the steps for the terminal screw plug, but work with three wires instead of two. The black wire, which is hot and carries the electricity, goes to the golden brass screw. The white wire is neutral and hooks around the silver screw. The green wire goes to the ground screw.
What are the 3 wires in an extension cord?
The green wire is the ground wire, the white wire is the neutral wire, and the black wire is the hot wire. Light-duty interior extension cords often lack the ground wire, but if a ground wire is present, be sure to connect it.
Which side of plug is black wire?
The hot side of the circuit (black wire) should be wired to the brass screws while the neutral side of the circuit (white wire) should be wired to the silver screws. You only need to connect to (1) screw on either side.
Does the color of an extension cord mean anything?
The color of an electrical extension cord does not refer to its use or function, but a system of color-coded tags has been suggested to mark a cord’s grounding compliance after inspection according to OSHA standards. Electrical extension cords need to be inspected for safety on a regular basis.
What are the blue brown and green wires?
Brown is your hot wire so you want to connect that to your building’s black wire. The blue is negative or return, so that will go to white. Green with yellow stripe is the ground and will go to the building green.
Which prong on a plug is positive?
The black wire is positive, the white wire negative, and the green wire ground. With speakers, you have a wire with a copper strand and a wire with a silver strand. The silver strand identifies the negative wire.
How do you tell which wire is hot or neutral?
Identify the neutral wire in the fixture by looking at the wires. In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means.
Which wire is hot on 3 prong plug?
The black wire is the hot wire. It becomes energized as soon as you insert the plug into a working receptacle. The white wire is known as the neutral or return wire.
Which wire is neutral on a cord?
The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. The green wire (or it can sometimes be uncolored) wire is the “ground” wire, it will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
Which is neutral in 3-pin plug?
The Three Pin Plug The LIVE wire is BROWN. This is connected to a fuse on the live pin. The NEUTRAL wire is BLUE. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero. The EARTH wire is GREEN & YELLOW. and connected to the earth pin.
What Colour wire goes to L and N?
The N is for the neutral side or the white wire, and the L is for the load side, the black wire.
Do you need an earth wire in a plug?
If the appliance, which has a plug connected to its power lead is double-insulated, then no earth wire is necessary, however if the appliance has a metal body, then it is best to ensure that the metal body of the appliance is earthed, just in case of a fault condition, as an earth connection to the metal case will.
Which prong is hot on extension cord?
If for a two prong plug, the wider prong is the neutral, the narrower is the hot. The neutral (wider prong) gets connected to the ribbed conductor, the hot (narrower prong) gets connected to the non-ribbed conductor. The ribs might be a little difficult to see, but they are easy to feel.
