14 3 Used for three way switches and split receptacle circuits 15 amp circuit maximum 12 2 Used for 20 amp kitchen bathroom laundry and garage receptacles 230 volt heating circuits up to 3 700 watts and 115 volt circuits up to 1 800 watts 14 2 or 14 3 with Ground rated for 15 amps general purpose lighting and receptacle circuits 12 2 or 12 3 with Ground rated for 20 amps kitchen laundry bathroom and garage circuits 10 2 or 10 3 with Ground rated for 30 amps clothes dryers and A C units
A rating of 14 3 refers to the gauge of the wire and how many conductors are in the cable In this case the wire gauge is fourteen lower numbers mean larger wires and the three indicates that there are three conductor wires in addition to a non insulated ground wire If it were wiring a three way switch that requires a 3rd conductor the user would have to use 14 3 wire which contains three conductors and one ground Wire Sizes and Their Uses The following are some common wire sizes and their uses 18 AWG Thermostats doorbells and other low voltage applications

Wire gauge is the physical size of the wire rated in gauge size For instance common sizes include 14 12 10 8 6 and 2 gauge wire The gauge of the wire indicates the amount of current that can safely pass through the electrical wire Electrical current is measured as ampacity A 14 3 NM cable 3 wire contains 3 insulated 14 AWG current carrying conductors black red white and a bare ground wire The 2 line wires are different phases A and B and share the neutral wire for return current NM Cable Circuit Ratings NM Cable Colors 14 AWG white 12 AWG yellow 10 AWG orange Wire AWG
Multi wire circuits smoke alarms interconnection separate switches for things like a paddle fan or bath fan light or switched receptacles etc We even use 14 4 to carry both a hot and neutral along with 3 way travelers from one switch to another to maintain the lighting circuit at the far end of the room ROMEX 14 3 was designed to be used on circuits that require 220 to 240 volts from the power panel ROMEX 14 3 cable refers to a type of electrical wiring cable used inside a home in dry areas such as attics and inside walls This cable contains four conductors a black hot wire a red hot wire a white common wire and a ground wire
