    Default Uses for 14/2

    Does anyone still use 14/2 anymore? and in what cases? I kno 15amp=14/2 or 12/2 20amp=12/2 but it seems like no matter what the scenario everyone says use 12/2. I have even been planning interconnected smoke alarms and people still recommend 12/2 and i know the load is nowhere near the limitations of 14/2. Opinions?

    The majority of general 15 amp circuits are still 14/2 --- it's not as common for 12/2 being used for general 15 amp circuits -- mainly because of the cost difference between the two gages of copper wire.

    Most people will recommend using 12/2 to DIYers because the circuit can easily be upgraded to 20 amp. Often the circuit contain lights and receptacles and DIYers usually don't know how to do load calculations..

    my general rule is, 12/2 for outlets and 14/2 for lights.. Im thinking you might want to use a 14/3 (not a 14/2) for your smokes though. they typically have a third wire that will interconnect all the devices. And a 14 guage wire is exactly what i would use, its SO much easier to work with!!!

    To interconnect smoke or carbon monoxide detectors you must use either 12-3 or 14-3, depending on the breaker size.

    Call me crazy but I've been carrying a roll of 14-2 & 14-3 around in my truck for 7 years and haven't used more than half of it, for repair work.

    Now that expensive AFCI's are required just about everywhere it just makes sense to use #12 wire to allow more outlets on the AFCI.

    Also, 12-4 w/G will begin to be used for 3 way (and 4 way) circuits since a neutral is now required at all switch locations, even if not needed at the time of the installation, with few exceptions.

    In my fair city, 14/2 is allowed for your regular 20amp outlets. Scary I know.

    Well actually you can use 14/2 on a 30 amp outlet, but it has to be protected by a 15 amp breaker.

    Sometimes I use this wire to bundle stuff, such as wrenches, sockets and other tools.

    Seriously, I use it from switches to the light fixtures.

    That works out pretty good because i have to get some 14/3 for the smoke detectors. Thanks for that extra note!!
