Preparing to cable my new home and have to buy 12-2 wire and 20A breakers for all baths, mine basement workshop, garage, and also the kitchen/dining area. Purchased 14-2 wire and also 15A breakers because that all various other outlet circuits and lighting circuits such together living room, hallways, and bedrooms. Now I"ve been told by a pair of other civilization that they would run 12-2 with 20A instead of the 14-2 through 15A breakers everywhere.I"m considering exchanging every one of my 14-2 and also 15A"s (about 2000" worth) because that 12-2 and also 20"s. Must I go through 12-2 and 20A"s in the bedrooms too since they require arcfault breakers? need to I go v the 12-2 just to "overwire" a little in the bedrooms for potential future lots such as computer systems (is 14-2 sufficient or 12-2 necessary for computers)? would certainly I be wasting money and some time due to the fact that 14-2 is cheaper and also easier to job-related with?Any thoughts/suggestions?

Absolutely go v 12-2 Wire and 20 Amp circuits. Not only are they much less fire prone because of overloading, but you"ll say thanks to yourself later.Other points to save in mind:Keep lighting off of wall plug circuitsDo no "Back wire" plugs. That takes much longer to usage the screw write-ups but it"s far less at risk to arcing and fires.Pull at least one extra circuit come the far finish of the residence for future use. (trust me ~ above this).I always say spend a little more up former on the wiring so you only have to do that once.

Why execute you think you require a 20 amp circuit? would certainly a 15 amp circuit perform the job? ns bet that will. Also your computer facility will no need an ext than 15 amps. Cripes, that"s 1550 watts. Therefore why upsize? Bathrooms, garages, and also utility rooms sure, there you will have hair dryers power tools and also irons. I don"t watch the must overwire whatever unless friend can present the need.
