In practical terms, fitting a mess of 14/2 wires into a box is a whole
lot easier and safer than the same number of 12/2 wires. Infact, code
says how many more 14/2 you are allowed.

There is nothing "easier" about going all 12/2, unless you can't tell
the difference between a "2" and a "4". Hell, here the 14 is even
yellow coated instead of white, so you don't even have that. Buy one or
two rolls of each, and replenish as needed.

And unless you have some wierd applience plug, then everything you have
is 15A or less, as are all the switches, lamps, outlets, etc.

I have a very small house and have begun wiring rooms with 12/2 with 20
amp breakers. I realize this is overkill especially for overhead
lighting (of which I have only 2 lights). But the increased cost
doesn't bother me and it makes my circuits and wiring job much simpler.

Also most of the lights and switches are rated for 15 amps with the
exception of outlets which actually need to support appliances
requiring a 20 amp circuit. The overhead lighting shares the circuits
with other lights and outlets.

Are there any problems wiring this way with regard to safety or code
violations?
