What is the difference between 12 2 and 12-3 wire?

What is the difference between 12 2 and 12-3 wire?

The designation 12/2 indicates AWG 12 wire with two conductors (AC scorching and AC neutral), 12/3 indicates AWG 12 wire with three conductors (two AC sizzling and AC neutral). AWG 12/2 is used for a unmarried breaker 120V 20A max circuits. AWG 12/3 is used for double breaker 240V 20A max circuits.

What are the wires in a 12-3 wiring?


12-Three NM (aka “Romex”) cable can have a bare grounding wire, white neutral (grounded) wire, black sizzling (ungrounded) wire, and red sizzling (ungrounded) wire. If you best see white, black and bare wire then it is in fact 12-2 (the 2d number is the selection of conductors, the flooring wire is no longer incorporated in this).

Can I exploit 12-3 wire for retailers?

No. First, one installs both a GFCI receptacle or a GFCI circuit breaker, but by no means both in the identical circuit. Secondly, 12/3 wire has white neutral, black line, inexperienced or naked copper floor and a pink wire now not needed for your 20a 110v outlet. All you need to buy is 12/2 which omits the red conductor.

What’s the difference between 12-2 wire and 14 2 wire?

A12/2 wire has two conductors and can raise 20 amps. A 14/2 wire has two wires, however can handiest carry 15 amps. The 14/2 wire can be utilized for lights or every other electrical equipment, however the load should no longer be more than 80% of the present capacity approximately 1500 watts.

Can you use 12-2 wire lights?

Yes, it is okay to use 12-2 cable to provide lighting. The different answer indicates that it even with 12-2 it’s a must to use a 15A breaker for lighting fixtures circuits which is not strictly correct. If the whole circuit is 12AWG (rather than fixture wires), then a 20A breaker may be used.

Can you utilize 14 gauge wire for shops?

14 AWG is superb for retailers in spaces like dwelling rooms, bedrooms, hallways, circle of relatives rooms… where maximum items that get plugged in there are lighter duty. However, 12 AWG (and, more generally, 20 amp circuits) are required in some areas (kitchen countertops) by the NEC.

Can I take advantage of 12 gauge wire on a 20-amp breaker?

Electrical plugs designated as 20-amp won’t fit into 15-amp outlets. A fifteen-amp circuit is most often served via 14-gauge wire and is safe via a 15-amp circuit breaker or fuse. A 20-amp circuit, protected by way of a 20-amp breaker or fuse, will have to be served through 12-gauge or 10-gauge wire.
