Applications: Non-metallic sheathed NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads.
Is there such a thing as 12/4 wire?
Southwire Romex SIMpull 12/4 Solid Indoor Non-Metallic Jacket Wire (By-the-Foot) in the Non-Metallic Wire department at Lowes.com.
What is 4 conductor electrical wire used for?
4-conductors are most often used to send an amplified stereo signal to two speakers which are in close proximity to one another or to a stereo volume control.
Is there a 12 4 Romex?
Price: $1.99.
What wire is used to wire a house?
Wire Gauge The most common sizes you’ll find in residential work are 14-gauge and 12-gauge. Larger appliances such as electric stoves, electric water heaters, electric dryers and central air units will often use 10-, 8- or even 6-gauge wire.
When should I use 4 wire Romex?
Electrical junction box with multiple circuits. Connecting a 4-wire and a 3-wire circuit at a junction box is used to connect two 120-volt circuits to one 240-volt line. This configuration is used most often for large lighting arrays.
What kind of Romex is used for outlets?
The following NEC regulations apply to Romex conductors: Wire Gauge or Type Rated Amperage Common Uses 14-2 Romex 15 A Lighting Circuits 12-2 Romex 20 A Lighting and Outlet Circuits, refrigerator 10-2 Romex 30 A Electric water heater, baseboard heaters 10-3 Romex 30 A Electric Clothes Dryer.
Why does my house wiring have 4 wires?
The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.
Can I use 12-gauge wire on a 15-amp circuit?
Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
What color is 12-gauge wire?
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.
What is the purpose of 12 2 2 Romex?

What’s Romex?
Romex is the trade name for a type of electrical conductor with non-metallic sheathing that is commonly used as residential branch wiring. Romex™ is a common type of residential wiring that is categorized by the National Electrical Code (NEC) as underground feeder (UF) or non-metallic sheathed cable (NM and NMC).
What does red wire connect to on ceiling fan?
Connect the red wire in the ceiling to the black wire in the light kit and the black wire in the ceiling to the black wire in the fan.
What kind of wiring is used in new homes?
The most common type of wiring in modern homes is in the form of nonmetallic (NM) cable, which consists of two or more individual wires wrapped inside a protective plastic sheathing. NM cable usually contains one or more “hot” (current-carrying) wires, a neutral wire, and a ground wire.
Should I use 14 or 12-gauge wire?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
Can I use 12 3 wire for a stove?
1 Answer. Not even remotely close. You need 8 gauge copper or 6 gauge aluminum wire.
Why do I have 4 wires in my outlet?
This circuit allows for the bottom receptacle to be switched while the top receptacle will remain hot at all times. To perform this circuit, you will need to use a 4-wire cable to allow for the extra circuit.
Can I use a 3 prong outlet with 4 wires?
It’s not code compliant to use a 4-wire receptacle on a 3-wire cord and place a neutral ground bond inside the receptacle box. If you need to, you can either replace the existing 3-prong receptacle with a new one or use a 3-prong cord kit for the range.
What wire is used for outlets?
Most household outlet circuits are either 15-amp or 20-amp 120-volt circuits. A circuit controlled by a 15-amp circuit breaker calls for 14-gauge NM cable and a receptacle rated for 15 amps. A circuit powered by a 20-amp circuit breaker calls for 20-amp receptacles, and it is wired with 12-gauge NM cable.
Can I mix 12 gauge and 14 gauge wire?
Originally Answered: Can I mix 12 and 14 gauge wire? The 12 gauge can carry more current, therefore; you must not use 14 gauge in place of 12 gauge, but you can use 12 gauge in place of 14 gauge, but 12 gauge is larger.
How far can you run 12 gauge wire on a 20 amp circuit?
Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? About 400 feet. After that voltage drop is a factor and the gauge will have to be increased or the voltage increased. You can run 50′ on a 12 gauge wire.
When should I use 12 gauge wire?
Using a 12-gauge wire is a safe bet for wiring a circuit that includes both lights and outlets, or if you’re not sure which gauge to use. It is more expensive and less flexible than 14-gauge wire, but it is always a good idea to use it on a circuit rated for 15 or 20 amps.
Can you put two black wires together in an outlet?
It is safe to have two black and two white wires in an outlet provided each wire is correctly attached to the terminal and insulated from contact with other wiring.
