What does L1 l2 and COM mean?
The single direction plane switch has two L1 terminals, the terminal to which the neutral cable is connected – the blue cable (traditional black, before changing). COM or Common is the terminal to which the live core cable is connected – this is the brown cable (red era).
How do you wire a light switch from a receptacle?
Youtube quote:So now with the black wires we just take a pair of needle nose. And we simply grab the very end of the wire. And give it a good twist. And put a nice sharp hook on them.
What type of electrical cable has wires covered with paper and vinyl?
part of the circuit. What type of electrical cable has wires covered with paper and vinyl? Aluminum wire: requires one size larger than copper wire to carry the same amperage.
Can Romex go in flexible conduit?
Yes, NM cable can be in conduit. In fact. NEC calls for it to be in conduit, when protection from physical damage is required.
Can you put two Romex wires one staple?
It is not permissible to secure more than one 3-conductor cable under a single staple. Use stacker-type fasteners to secure multiple cables to the same framing member. These allow the cables to be stacked for a neater, safer installation.
Can you put two wires knockout?
Never run two cables into the box through the same knockout opening with pre-installed cable clamps. Each cable requires its own knockout opening and clamp. For installed clamps (whether they’re metal or plastic), no more than 2 wires should be installed in each connector of this type.
How many wires can be in a 3/4 hole?
my inspector told me that they must not take up more than 50% of the capacity of the hole, or 4 wires max through ANY size hole. he said 3 12-2 wires is pushing it for 3/4″, but is still okay.
How many Romex wires can you put under a staple?
Most metal and plastic staples or ‘wire holders’ can hold stacks of up to six to eight (6 to 8) Romex wires under them. You can stack even more if you can fit them or use thinner wires. However, it is not permitted by code to stack more than one 3-conductor cable under a staple, be it metal or plastic.
How far apart do you staple electrical wire?
One of the requirements for permanent wiring, and thus for temporary wiring, was the need for adequate support. Article 336-18 stated that cable must be secured in place at intervals not exceeding 4.5 feet (1.37 m) and within 12 inches (305 mm) from every cabinet, box, or fitting.
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.
Where do I drill electrical wiring?
When running cable through studs, drill all holes at the same height so that the cable is run level to the floor. Drill holes 6 to 8 in. above or below all switch and receptacle boxes.
Where do you drill holes in joists for wiring?
You can drill the holes anywhere along the length of the joist (first photo). If you have manufactured I-joists, you can drill holes up to 1-1/2 in. diameter almost anywhere in the web area (the area between the flanges).
How thick is Romex wire?
The cable jacket is color-coded for quick size identification; White – 14 AWG, Yellow – 12 AWG, Orange – 10 AWG, and Black – 8 AWG and 6 AWG. Insulation Thickness (mils) Ground Wire Approx. + Ampacities per National Electrical Code section 310.15 and 334.80. NOTE: Jacket thickness for all NM-B cable is 30 mils.
What is the difference between 14 2 wire and 14 3 wire?
Youtube quote:3 what's the difference. Well if you look inside the jacket of a 14 2 wire you will see a black wire a white wire and a bare copper wire that's your hot neutral and ground wire.
Is 12-gauge Romex always yellow?
Yellow color-coded cable sheathing encloses 12-gauge wires. Yellow 12-gauge cable is typically used for 20-amp circuits that power general household outlets used for a variety of plug-in appliances. Dedicated appliance circuits also call for 20-amp circuits in most cases.
