If you need to run cables through a wall, simply drill a hole in the wooden plank in the attic. and use semi-rigid tape to pull the threads towards the socket. If the points you want to wire are outside your home, you don’t have to drill a new hole.
You can cover the opening with a wall plate. As you make your way through the attic, use the spade to drill a hole in the top plate, just above the new electrical box. If you are running a cable through a basement or crawl space, drill a hole in the floor panel just below the closet.
The attic cable can be a non-metallic cable (NM cable), as long as the NM cables are approved in your area. It is licensed in most of the United States.
Confused about the rules for guiding Romex through the ceiling joists. If you can crush it by attaching it to the rafters, you can avoid the point of isolation. When the penthouse is out of reach, you need to worry less about cable protection than if there was storage space.
Yes, that’s fine From the NEC’s point of view it would also be good to drill the trusses and run the cable through them. As long as they are at least 1 1/4 of the nail surface.
If there is no insulation in your attic, you will need to install insulation between the joists. Do not squeeze the insulation to fit behind pipes or cables. Instead, cut half the thickness of the bat so that you have one flap under the yarn and one above the yarn.
Junction boxes in an insulated attic
- Attach a small magnet (small enough to fit through the hole in the box) to the cable.
- Connect the other end of the cable to the end of the cable.
- Send the string and thread through the wall near the box.
- Attach a metal rod or fish tap or something with the magnet attached through the hole.
- Move around until the magnet clicks into place.
Cable lengths parallel to rafters or joists should be clipped to approved lengths and held against the edges of rafters or rafters with 1 1/4 or nail plates to protect the cable. You cannot put the wire on the beam or tie it under the beams.
If I understand what you are asking, you can staple Romex along the side of a floor joist a safe distance from the edge to protect it from screws or nails. It is not acceptable to run a bundle; H. thread the bundle of threads so that it shines downwards. This is when you need to drill holes. B. for the use of bent nails as fasteners.
You can never drill or cut a farm. They don’t need to be replaced, but they will be expensive to repair.
Yes, unless it is in an inaccessible place. like behind an air conditioner or something. Here we can only run NM through the joists if it is in area 2, measured from the top of the roof joist to the bottom of the roof joist, and we need to connect all 4.
If it’s a dimensional wood beam, keep the hole at least 2 inches from the top and bottom. The hole should not exceed one third of the depth of the radius, so the maximum hole size for a 2 × 12 radius (actual size 11/2 x 111/4 inches) is 33/4 inches in diameter - large enough to pass through the cables !
The insulation is always easily connected to the NM cables. The cable is only needed if it is physically damaged.
334.30 The connection and fastening of non-metallic cables must be spaced no more than 1.4 m (4 1⁄2 ft) and within 300 mm (12 inches) of each junction box.
Use electricity or duct tape to wrap the wires where they will bend. This will prevent the ribbon and thread from falling apart. Return to the hole in the ceiling light. Roll and fold the masking tape that pulls the electrical cord with it as it winds through the wall and ceiling.
