Can I run electrical wire in attic?
Can I run electrical wire in attic?
An attic can be a hazardous work space. New lighting, cable, computer networking and sound systems can all require wiring that may need to come through the ceiling. On a single-story home or the the upper floor of a multiple story home, this means accessing your attic to run wire.
Can you run electrical wire through rafters?
Yes, that is fine. NEC wise it would also be OK to drill the rafters and run the cable through them. As long as they are at least a 1 1/4″ away from the nailing face of the rafter. I would keep them greater than that though.
Does electrical wire in attic need to be in conduit?
No, conduit is NOT required in attics. Not unless conduit is required in your area. There are other factors involved in wiring in attic spaces, but your question is a bit too vague to go into that. You only have to put the wiring in conduit, if you have to protect it from physical damage.
What kind of wire should I use in my attic?
Use 12/2g NM-B cable; the cable is typically yellow and sold under the brand name Romex. When you run the cable in the attic, be sure it is installed such that it cannot be accidentally stepped on. The usual way of doing this is running it alongside a 2×4 if you must go perpendicular to the joists.
Are outlets allowed in attic?
Re: receptacle in attic Nope, not allowed, not unless there is an access walkway to it. Yep, not only allowed, it is required if you have HVAC in the attic, very common here. That’s because there is an access walkway to it (at least, there is supposed to be).
How do you seal an electrical box in an attic?

In general, he recommends plastic boxes for switches and receptacles and metal boxes for light fixtures. Metal boxes are required when the existing wiring in the home is metal clad cable and must be bonded to the ground wire.
Can you run 2 circuits in conduit?
Actually, you can have more than one circuit feeding an outbuilding if it has different purposes or operating restrictions; or it has different voltages; and several other exceptions described in NEC 225.30. (however your inspector may say it counts as a 120V circuit, so it’ll be your only one if so.)
Can 2 separate circuits share a neutral?
It is NOT permitted to share a neutral in any other situation. If you were to share a neutral with two breakers on the same leg of a panel, both circuits could draw the breaker limit (lets say 15A) making the shared neutral as much as 30A return current!
How many outlets can you put on a 14-2 wire?
12 outlets
Will 14-gauge wire carry 20 amps?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals.
