Attach to Stud or Joist. Yes you can wire them up first. Because they are plastic , there is no need to attach a ground wire to it.

Since it is made of a non-conductive material, switches and outlets cannot short out if they touch the side of the box. Plastic boxes usually come with tapped screw holes for easy attachment of switches and outlets. One exception to the rule specifying foot placement of outlets : If the wall is less than 24 inches wide, an outlet is not required. Again, you are allowed to place an outlet in this space if you so choose.

Hallways more than 10 feet long must have at least one electrical outlet , preferably at the mid-point. If a cable is run from the panel to the outlet, then a 20 amp circuit breaker is the largest that can be installed to protect the circuit. Support cable. Prepare the cable for entry into the box. The end of the cable needs to be carefully stripped of the outer jacket prior to installing into the box. Strip back 8 inches Install cable into box. Use of plastic or fiber electrical boxes are quicker to work than steel boxes because they do not require additional grounding.

A steel box must be grounded so that it does not require the device for it to be grounded pigtailing the ground to the device AND the box solves this. Connect the neutral wire to the device. The white wire neutral wire needs to be secured under either silver screw on the side of the receptacle. Connect the "hot" wire to the device.

The black wire "hot" wire needs to be secured under either gold screw on the opposite side of the neutral wire. Connect the ground wire. The free end of one wire will connect to the green ground screw of the outlet, and the other free end is to be connected to the metal box with a green screw expressly for that purpose or other approved means special clips, etc. If a plastic or other non-conductive material box is used, simply connect the bare copper wire directly under the green screw of the outlet.

The ground wire is usually green and connects to the green terminal. Gently fold the wires to the rear of the box and secure the outlet to the box and attach the wall plate. Remove the panel cover, and set aside. Exercise extreme caution working near this switch. These are available in a variety of styles, and materials. The easiest to install are the low profile plastic push in type.

Cut cable to length. Again, strip the entire jacket except to allow for about an inch of jacket cable inside the panel. Wrap the end of the cable with a couple of turns of electrical tape. Push the cable through the connector and help pull it with your other hand once it enters the panel. Once about an inch of jacketed cable is INSIDE the panel, stop advancing cable, and secure it within 18" of the panel with an insulated staple.

Inspect the panel. Look carefully at the bar s. Regardless of which type you have, you must maintain the integrity of the grounding and neutral systems by duplicating the termination scheme outlined below. Connect the neutral and ground wires.

The white and ground bare wires are to be secured under the bar s in the main panel. Cut these wires to length PLUS 12 inches If you have the combined neutral and ground style, secure these two wires in terminals as close together as possible. Do not install BOTH wires in the same terminal!

If you have separate neutral and ground bars, install the wires in the respective terminal bar. Connect to the circuit breaker. Cut this wire so as to allow it to be connected to ANY breaker position in the panel - plus a little slack.

You never know when you might have to move the circuit to a different location in the panel, having enough wire to do so will make the job much easier.

Set the handle of the circuit breaker to OFF. Install the circuit breaker into the panel by first hooking or clipping to the grounded or insulated slot or rail manufacturer dependent on the outboard side of the insulated electrical contacts, then line up the clip or slot of the circuit breaker with the electrical contact rail or bus.

Jodie Thank you for a helpful question on electrical box size for two light switches. A typical 4-inch box is the right size, but the actual box dimensions, in particular, box depth and thus the space needed in cubic inches varies depending on how many wires or connectors will be in the box.

Take a look at the tables above on this page for details and you'll see that more connectors means more cubic inches means a deeper box.

Pp Thank you for your interest, but to protect reader trust that our articles are written without bias or conflict of interest we don't sell any product or service and therefore we have no dealer in India nor anywhere else.

Glen I'm not sure how you're using the word opening or where the concern lies in the question. Obviously the front of the box as a single opening into which devices are secured.

However electrical box may have multiple openings for wiring connections. The number of those will vary as the box size varies. Lake We use electrical boxes of varying sizes or capacity in cubic inches because the number of electrical wires, connectors, devices varies as well. More devices require more cubic inches, as per tables of electrical box size given in this article series. Good luck on your test. The answer to your perfectly good question depends on the cubic inches that the Box provides matched against the table of cubic inches required for the number of wires and connectors by wire size in the circuit that you are wiring.

I am putting outlet in garage wall that has kitchen on the other side. What is code, plastic or metal? I would think in a garage fire that a plastic box would melt and fire would go through the wall faster? Steve both plastic and metal receptacle boxes are code-approved and neither, properly installed and wired, should violate the fire-rating of the wall. I am unable to find instructions on how to increase the projection into the room of existing electrical outlets so that I can tile the kitchen backsplash and have the outlets be at the appropriate depth for use and safety.

Do I move forward the box to which the outlet is screwed and if so how? Building suppliers like Home Depot and also your electrical supply house sell "box extenders" in varying thicknesses, made of plastic, code approved, for the purpose you describe. The electrical box extender is sized and shaped to match the electrical receptacle box to which it is to fit. By removing the electrical receptacle from its mount on the existing box, the box extender is fit as a sort of large rectangular plastic washer, mounting between the existing box edge or surface and the mounting ears of the receptacle or switch.

The plastic electrical "gang box extension" shown at above left is produced by Arlington Industries but there are several manufacturers. Just choose an electrical box extender that brings your receptacles far enough forward to suit the thickness of the kitchen backsplash or tile.

Watch out : don't try a makeshift substitute using washers or junk - that's an improper and unsafe repair, leaving a gap around the electrical box sides.

Anne, I'm in the midst of a remodel that posed the same 'problem'. Work box extender rings are available at Home Depot and Lowes in the electrical department. The frames are available in multiple thicknesses. I suggest you take a tile sample with you so that you can get the correct thickness for your project.

Depending on the thickness of the tile, you may need to combine two frames of different thicknesses. While I was changing a failed plug I noticed that the box was too deep.

I looked into extenders, and plastic ones Arlington BE1 are less expensive. Are CSA approved plastic box extenders code compliant for homes?

John K:. Our photo left shows a Amp electrical receptacle - you can recognize it by that horizontal opening that makes the left-hand slot look like the letter "T" on its side.

Our photo left illustrates an electrical receptacle intended for use on a Amp circuit. Notice that extra horizontal slot? You won't see that on a Amp electrical receptacle. When running wire for a basement, is there a min height the wires must be off the ground? Not the outlet box, but the wire running through the joists. Justin Sheppard.
