How to Wire a V Outlet (with Pictures) - wikiHow
Turn off the main power on your circuit breaker box. Open the door on the circuit breaker box in your home, usually located in a basement, hallway, or kitchen. Look for the breaker switch that controls all the power in your home, which should be alone on either the top or side of the box.
Never work on your electrical system while the power is still on. Doing so could result in serious injury or death. Use a contact voltage tester on the wires inside your circuit breaker box to see if they still have power if you want to double check if they have a current through them. Use a drywall saw to cut through your wall along the outline you drew so that you can set the outlet box inside.
Deeper outlet boxes work best since you have to hide multiple wires inside of them. You can also choose to mount the outlet box directly on your wall, which may be easier if you have cement or brick walls.
Measure the distance from the circuit breaker box to where you want to place the outlet. Find the shortest route from the hole you cut for the outlet to the main circuit breaker box in your home. You may need to go through the floor or the walls in your home to find the shortest route. Extend a tape measure from the outlet box along the path you chose to the circuit breaker box and record the measurement.
You may need to take multiple measurements depending on the layout of your home and the obstacles between the outlet and circuit breaker box. Once you are certain you have the right amount of cable, use a pair of wire cutters to cut through the ends of the cable. You may also use 8-gauge wires if for your outlet if you want.
Drill or cut a hole near your circuit breaker box so you can run the cable to it. Install electrical conduit between the breaker box and the hole you drilled. Wires for lines cannot be exposed outside of your walls since they could easily get damaged, which could cause serious injury or death. Get enough rigid metal conduit to run from the side of the breaker box to the hole you cut and attach it to your wall using conduit straps every 1—2 feet 30—61 cm.
Fish the cable through the walls between the outlet and breaker box. Use a fish tape, which is a long flexible cable with a hook on the end so you can easily pull wires and cables through your wall. Feed the fish tape into the hole near your circuit breaker box and push it through toward the hole you cut for the outlet box. Go back to your circuit breaker box and reel in the fish tape so it pulls the cable with it back through the hole. You can buy metal conduits from your local hardware store.
Screw the outlet box into the wall so it stays in place. Part 2. Pull the wire stripper toward the end of the cable to cut through the outer coating and expose the wires inside.
Pull the wire stripper toward the end of the wire to cut off the insulation. Repeat the process for the other 3 wires that were inside the cable. Feed the white wire into the slot with the neutral screw on the outlet. Use a screwdriver to tighten the screw and clamp the white wire in place. Attach the green wire to the grounding screw on the outlet. Look for the grounding screw labeled "Green" or "Ground" directly across from the neutral screw.
Put the black and red wires into the hot ports on the back of the outlet. There will be 2 unlabeled screws left on the back of the outlet, which are known as the hot screws. Place the end of the black wire in the port next to one of the unlabeled screws, and the red wire in the port on the other. Push the wires and outlet into the box so you can screw it in place.
Bend the wires so they can fit in the back of the box. Push the outlet in front of the wires so the screw holes on the outlet line up with the ones along the sides of the box. When you need to access the wires, unscrew the wall plate so you can get to them. Part 3. Remove the safety panel from the front of the box. The safety panel on your circuit breaker box is the cover that hides all of the wires and breakers inside. Locate the screws around the edges of the circuit breaker box and rotate them counterclockwise to loosen them from place.
This could cause to get electrocuted. Take out the circular knockout on the side or top of the circuit breaker box. Inspect the sides or top of the circuit breaker box to look for a circular piece that has a precut edge around it, also known as the knockout. Be sure to use a drill bit meant for metal. Put a cable clamp in the hole you just knocked out. Get a cable clamp that matches the size of the knockout on your circuit breaker box, and slide the clamp through the hole.
Screw the locking nut onto the threaded end of the clamp to hold it securely against the box. Feed the wires from the cable through the clamp into the box. Pull the wires into the box completely so you have 1—2 feet 30—61 cm of wire to work with. Install a amp double-pole breaker on the circuit. A double-pole breaker allows twice the power to run through it as a standard amp single pole breaker, and takes up the same space as 2 single-pole breakers. Find a spot along the line of other breakers where the double-pole breaker will fit.
Push in the top of the breaker into the metal clips inside the box so it snaps into place before pushing the bottom into place. Make sure you get a breaker that matches the circuit breaker box brand you have.
Make sure the breaker is off before you install it. Push the ends of the red and black wires in both ports of the breaker. Take the ends of the black and red wires and feed one of them into each of the ports. Tighten the screws on the bottom of the breaker with a screwdriver to hold the wires in place. Wrap the green and white wires around the screws on the grounding bar. Look on the inside walls of the circuit breaker box to find a bar with multiple screws and wires attached to it, which is the grounding bar.
Bend the ends of the green and white wires into hooks and wrap them around separate screws along the bar. Hold the safety panel up to the circuit breaker box so you can find where the new breaker lines up with it. Place the end on your screwdriver over the slots where the breaker would go, and tap the end with a hammer to punch it out. Pull off the piece of the safety panel you punched out so the breaker fits easily. Screw the cover back on the circuit breaker box before turning it on.
Hold the panel back up against your circuit breaker box and reattach the screws with a screwdriver. Make sure the safety panel sits tightly on the front of the box and that none of the wires are exposed. Lay the cable into the outlet by first lining up the jacket so that it will just be visible into the outlet body. Arrange the conductors to lay into the terminals. The black and red conductors will land in the gold terminals it does not matter which of these two conductors land in the left or right gold terminals , the white conductor will land into the silver terminal and the uninsulated conductor will land in the green terminal.
Cut the conductors for the outlet. Carefully strip the cable as per the strip gauge indicated on the range outlet. Be sure to remove all insulation from the part of the conductor that will be in the terminal. A nicked conductor must be cut back and redone. Since the working area in the outlet is so small, all the conductors will have to be re-cut to length and stripped over again.
Apply oxide inhibitor. If using aluminum cable, apply a generous coating of aluminum oxide inhibitor to the individual stripped portion of the conductors and into the wire compression terminals of the range outlet the amount of inhibitor should not be so much that it drips from the conductor or terminal. Application of oxide inhibitor to aluminum conductors is a code requirement, and must not be skipped.
Secure the range outlet to the wall or baseboard in a location where when the range cord is connected, will not interfere with placement of the range and closing of any range drawers. Inspect the back of the range to get an idea as which locations will meet this requirement. Often times, removing the drawer will allow access to the wall - where it may be marked with a pencil, etc. Install the outlet cover and press any excess range cable back into the hole.
Remove excess slack from the cable. Allow for 10" or so of slack available should it need for later use - the cable can still be used , and pull the rest back to the electrical panel. Route the cable to the connector mounted in the electric service panel. Mark the cable jacket where it will be clamped at the locknut side of the connector. Determine how much cable will be needed to a. Add 2 feet 0. Install the cable into the electric service panel through the cable connector.
Remove the jacket and any plastic shielding from around the conductors. Untwist each of the four individual conductors. Connect to the circuit breaker. Locate an existing red wire in the panel - in either column of circuit breakers.
The new red wire will be connected the same way - if existing red is EVEN then the new red will be connected to EVEN or if existing is odd connect new to odd. Determine if the top terminal of the new circuit breaker when installed is the even or odd terminal. Cut to length needed, strip and install the red wire and black wires under the appropriate terminal after applying the oxide inhibitor compound to the stripped portion of the conductors.
Connect to neutral and ground terminals. Most homes with a single electric service panel have one bar to provide both neutral and ground conductor terminations. If the electric service panel is a sub-panel, there should be separate bars for neutral and ground terminations. It is easy to determine, but very important to connect correctly. ONE BAR If there is one bar in the electric service panel, and both the bare AND white insulated wires are connected to it, bring each of the bare and white insulated range conductors into separate unused terminals.
Secure the range cable with staples where exposed as needed for support and so that there is no less than 36" between supports every other joist or stud.
Cables run through bored holes floor joists, rafters and those laying on ceiling strapping are considered supported and do not need to be stapled.
Secure the cable within 18" of any electrical enclosure or box it enters. Remove the blank plates from the cover that are now occupying the place of the new circuit breaker. Check for any tools, parts or other foreign objects accidentally left in the electric service panel. Secure the cover to the electric service panel and set the new circuit breaker to OFF. Stand to the side of the panel do not stand directly in front and move the main service disconnect handle to ON.
While still to the side, move the new circuit breaker handle to ON. Check for proper wiring. Using a voltmeter, check the new range outlet for proper voltages. If any measurements are not exactly as described, turn the new circuit breaker OFF and check the wiring of the range outlet, and if necessary the wiring in the electric service panel as well. Correct any improperly wired connections and test again. Re-connecting the range. After the new outlet is wired correctly, shut off the breaker, then push the range plug into the outlet.
Set the range into place. Wrap up. Update the panel directory to reflect the addition of the new circuit breaker and new positions of old circuit breaker if any needed to be moved. Make sure all circuit breakers have been turned back on. Daniel Stoescu Master Electrician. Daniel Stoescu. Not really, but you must be aware that a V line has two hot wires. Always make sure the breaker is off and connect the two hot wires to the proper terminals, which are usually labeled with X and Y.
Also make sure the connections are snug. Yes No. Not Helpful 1 Helpful 1. On a four-prong, a copper wire is attached to white. Where does the green wire go? On a four-prong, the black and red wires are power; the white wire is neutral; and the green wire is the safety ground. But older models may only use the black and red wires for power, and the plain copper wire for the ground or neutral. You can attach the green wire to any permanent metal part of the stove for safety.
Not Helpful 0 Helpful 7. It can be behind the stove as long as there is enough room for the wires to fit without being pinched when the stove is shoved back in place. Not Helpful 1 Helpful 2. Include your email address to get a message when this question is answered. A circuit breaker must be the same brand as the panel in which it is to be installed. Further, it must of a type approved by the manufacturer for use in the particular panel.
Just because "it fits" does not mean it is suitable. The electric service panel door should at the very least have the manufacturer's name and model. There may also be a comprehensive list of acceptable circuit breakers approved for use.
Installing a circuit breaker not meeting all these requirements is voids the UL listing of the entire electric service panel and is a serious code violation. Helpful 0 Not Helpful 0. Oxide inhibitor is sticky and messy. It is difficult to clean up and will stain clothes and upholstery.
Remove excess oxide inhibitor from hands and tools before contacting absorbent materials. The National Electrical Code "the code" mandates that all new range and dryer outlets be "four wire" circuits line 1, line 2, and have separate neutral and ground conductors and be connected to the range or dryer with a four wire cordset. Existing ranges with the older 3 wire type MUST be changed to the updated 4 wire cord-set in order to connect to the new outlet.
Installing a "4 to 3 wire adapter" is not permitted. Installing a new "three wire" range outlet is also prohibited. Four wire cord-sets can be purchased inexpensively at any appliance or hardware store, and are fairly easy to connect. Helpful 1 Not Helpful 0. Ranges and dryers are dedicated appliances, and as such, are not allowed to be connected to a circuit that is shared with another appliance or load. Always apply for an electrical permit before attempting this work, and have your work inspected by the local authority having jurisdiction.
Never attempt electrical work if you do not understand what you are doing or the hazards involved. Aluminum conductors must only be connected to terminals that are rated for aluminum. If terminals are rated "CU" only, aluminum conductors are not permitted to be connected. Most circuit breakers and range outlets have the dual rating.
