How do you run wire through ceiling joists?
Basically staple all parallel runs 1.25″ away from the joist edge. All perpendicular runs should pass through a bored hole 2″ from the edge of the joist. Support wire every 4-6′ with either staple or through a bored hole. Staple wire within 12″ of entering a box or bend.
Should cables be protected in walls?
All cables should either be contained in steel conduit or protected by 30mA RCD. If these two cannot be met, then the cables should be installed at least 50mm (2″) from the surface.
Can you run electrical wire through ceiling joists?
Running electrical wire through the channel between ceiling joists is generally easiest. In addition, your light fixture may require mounting to a ceiling joist or to two short blocks nailed between the joists. Trace and mark the fixture hole and cut out with a drywall saw, utility knife or reciprocating saw.

What can I use if I don’t have fish tape?
A fish tape is a thin, flexible steel tape, typically 1/4 to 1/2-inch wide, that comes on a large reel, similar to a surveyor’s tape measure. Heavy gauge wire can be used to create a fish tape. Much of the wiring in new construction can be done without it, since the interior of walls and ceilings is still accessible.
What is a fish tape tool?
Fish tape is a tool used by electricians primarily for pulling electrical or other wires through conduits. The fish tape itself is a long, stiff, flat steel wire. Available in 25-, 50-, 100-, and 200-foot lengths, the fish tape is rolled up and stored in a round, plastic casing.
How deep should wires be chased into walls?
Horizontal chases should be no deeper than one sixth of the wall thickness – with standard 100mm blocks, that going to be 16mm which is usually quite sufficient – that’s not allowing for any plaster coating. Chases on opposite sides of a wall should not be in line, i.e. ‘back to back’.
How deep should wire be buried?
Bury in the Ground: Dig 24 inches There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
Can you bury cables in walls?

How do you rough in electrical wires?
Mark the Box Locations. Measure and mark the center of each box. Place the Box on the Framing Member. Drill into Corners at an Angle. Thread the Cable Through the Holes. Run the Cable Around Corners. Knock Out a Hole in the Box. Cut and Strip the Wires. Push the Wires into the Box.
How do you cover exposed wires inside?
How to Hide Wires in a Wall Use a stud finder to find a spot between two studs in the wall. Mark the wall where you want the upper and lower holes to go. Attach a drywall hole saw bit to a power drill. Insert the cord or cords through one of the hole covers. Insert the hole covers and push firmly into place.
How do you hide electrical cords in the middle of the room?
For cords that are still exposed, be sure you weight them down with a rubber cord cover (you can hide that further by applying contact paper, like wood-grain). Use baseboard clips or wall clips to affix cords to the wall or floor. It will help hide cords further and help eliminate tripping hazards.
