What is a 12 2 nm wire?
What is a 12 2 nm wire?
NM-B is primarily used in residential wiring as a branch circuit for switches, outlets and other loads. NM-B may run in air voids of masonry block or tile walls where locations are not damp.
What voltage is 12 2 wire?
NM-B is rated at 600 volts and although it is rated at a conductor temperature of 90°C dry , its ampacity is limited to 60°C according to the NEC 2008 and NEC 2011….12/2 NM-B Cable Specifications*:
| Cable Type | NM-B |
|---|---|
| # of Conductors | 2 Conductors w/ Ground |
| Conductor Material | Bare Copper |
| Ampacity | 20 |
| Jacket Color | Yellow |
What is 12 gauge NM wire?
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.
Can 12 gauge wire handle 20 amps?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
What does NM stand for in electrical wiring?
Type NM stands for nonmetallic sheathed. The cable consists of a factory assembly of two or more insulated conductors within an overall nonmetallic jacket.
Will a 12 2 wire carry 30 Amps?
A 12-gauge wire is rated to be safe up to 20 amps and therefore, should be used only on a circuit where the current will not exceed this value.
Can I use 12 2 wire 220v?
The same 12-gauge wire can be used for a 220v, 20-amp outlet to run power tools. You need a different type of receptacle and 10-gauge cable if the appliance draws 30 Amps.
What is nm b wire used for?
NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. NM-B cable may be run in air voids of masonry block or tile walls where such walls are not wet or damp locations. Voltage rating for NM-B cable is 600 volts.
