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.

Can you drill holes in ceiling joists?

Can you run Romex through ceiling joists?
Yes, you can run cable through bored holes in the joists if that’s what you prefer. Rarely have I worked on a job where the amount of cabling was substantial enough to warrant engineering/structural integrity concerns. Pipe – yes; typical Romex – no.
Can I run wires through joists?
Code says that you may not staple wires to the bottom of a floor joist unless the wire is 6-2, 8-3, or larger. Smaller wires must be run through bored holes or be attached to a running board.
Can you rewire a house while living in it?

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.
Can you leave wires exposed in ceiling?
Yes. This is not only safe but best practice. Tuck the capped wires completely into the junction boxes to avoid accidentally snagging on passing ladders, wallboard, etc. If the room continues in general use then install blank cover plates.

How do you cover exposed electrical wires inside?
Electrical tape is the simplest method of making electric wires safe. You also use tape on capped live electric wires as an extra precaution. Tapes can be used on loose live wires that do not fit the cap. You can simply use tape over the live wire to fit into the cap.
How do you feed wire through a cavity wall?
Round off both square cut ends of the tongue with a file to form a blunt point. Drill a small hole (about 2/10 inch) in both ends of the tongue to enable a cable to be looped through. Push the tongue into the wall and feed it through until it appears at the other end.
How do I run Romex in my basement?
Running Romex Wire in Basement You will have to drill a hole in the floor plate (attic) and roof or wall plate (basement) to run the wire. Make sure it is in the same wall cavity as the outlet you are trying to run the Romex to, since you can’t leave it exposed. To run the wire through this hole, use a coat hanger.
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 Romex be exposed in attic?
Yes. NM cable may be exposed in attic. This is very common in modern dwellings. Armored cable / MC is not necessary in your case.
Can you run electrical wire through ceiling joists?
Running electrical wire through the channel between ceiling joists is generally easiest.

What size hole do you drill for electrical wire?
Most electricians keep their inspector happy by drilling 3/4-in. holes dead center on a 3-1/2 in. wide stud. This gives them a hole large enough to run two electrical cables and leave 1-3/8 in.
How many wires can you put through a hole?
According to the National Electrical Code, you can have 4 12/2 nonmetallic sheathed cables through a single bored hole that is fire- or draft-stopped using thermal insulation, caulk, or sealing foam, or where proper spacing is not maintained for more that 24 in.
