The green wire is for ground. You can attach that to any metal part of the frame. The red is the active and coincides with the lefthand prong into the plug and the black in this case should be the Neutral and ciocides with the right prong into the plug as seen standing behind the plug.
No, the wide prong is neutral it is the white wire. The narrow prong is hot it is the black wire. The round prong (in a 3 wire plug) is safety ground it is the green wire.
Black wire to the gold screw, white wire to the silver screw, green wire to the round or U shaped prong screw.
all wires should be color coded, that is black-hot, white-neutral, green-ground. national electrical code been in use since the dark ages. if the wires are not colored, take a continuity tester, test from the cord cap to each wire on the opposite end of the cord. the larger straight prong on the cord cap is the neutral, mark it with white tape, the smaller straight prong [parallel to the larger prong] is the hot, mark it black. the " u "shaped prong is the ground wire, the mosat important of the 3. mark it green. on the continuity tester, the light on the tester will light when you touch the correct prong to the correct wire
Basically, Your ground prong is essential to protecting you from being in contact with an "unsuspecting Live current flow." It eliminates YOU as the primary grounding to whatever your plug is supplying power to, and sends any current flow, manually drawn (like touching it), into the ground prong. Your feet touching the earth acts as a "grounding" process, but with a ground prong; itself alone acts as the ground for you, allowing you to escape the ability to receive external power.
The equipment grounding conductor is attached to the rounded prong in a three prong plug. Electrical work is dangerous, call a qualified electrician to install. Improper wiring could lead to personal property damage, you or someone else being injured or killed!
The forth wire is to ground the body of the dryer. The cord should have red, black, white, and green wires. Red and black are hot, the white is neutral, and green is ground. The red, white, black in that order or reversed, black white, red, should go in a row where they connect to the dryer with the green one probably above it. If the center neutral lug has a bond to the chassis remove it. You have a dedicated wire to replace it now.
To properly wire a 3 prong outlet, you need to connect the black wire to the brass screw, the white wire to the silver screw, and the green or bare wire to the green screw. Make sure to turn off the power before starting and follow the manufacturer's instructions carefully.
To test a 2 prong sealed beam light, first disconnect the light from the power source. Then, using a multimeter, set it to the continuity test mode. Touch one lead of the multimeter to one prong and the other lead to the second prong. If the multimeter beeps, it indicates that there is good continuity and the sealed beam light is functioning properly.
To adapt a three prong range cord?æto a four prong outlet you need to remove the screws from the back plate to open the electric access panel. Then, pull out the copper grounding strip attached to the middle terminal. Next, remove the green ground screw from under the terminal block and attach it to the four prong outlet.?æ
The second ground prong grounds the frame and shell of the dryer. You can attach it anywhere on the frame if there is not a specific terminal for it, or just ignore it. The two hot and 1 ground should let it function. Do not ignore the green wire or grounding conductor. Remove the bonding jumper from the neutral terminal (grounded conductor, white wire) that bonds the neutral to the metal frame. The screw on the metal frame of the dryer the bond strap connects to is where you want to land the green wire. Save the bond strap you might have to convert it back to three wire in the future.
A four blade dryer plug cord should have a red, black, white, and green wire in the cord set. The red and black wires are the ones that deliver the 240 volts to the dryer. Black and white deliver control 120 volts to the dryer and also drive the motor to turn the dryer drum. On some dryers they use the red and white for the motor and black and white for the control. As for the green it is always the ground wire.
To wire a 4 prong dryer outlet correctly, connect the red and black wires to the outer terminals, the white wire to the center terminal, and the green wire to the grounding screw. Make sure to follow the manufacturer's instructions and turn off the power before starting.
