Let me rephrase...

#12 Romex = 20 amp circuit = 20 amp circuit breaker = use 20 amp rated
outlets/switches
#14 Romex = 15 amp circuit = 15 amp circuit breaker = use 15 amp rated
outlets/switches

#14 Romex is slightly thinner and somewhat more flexible and easier to work
with than #12.

#12 Romex will not fit in a 15 amp outlet. #14 will fit in a 20 amp outlet,
but it won' t be a tight connection (if it feels loose or has play in the
connection - you're using an outlet rated higher than the circuit).

You can run 15 amp outlets on a 20 amp circuit - no issues there, but for
the ease of wiring it up - it's best to use the outlet matched to the
circuit (I found this out the hard way when putting new outlets in a house
we just bought - our dining room is on a 20 amp kitchen circuit - was bit of
a bitch connecting #12 wire to the screw terminals since I couldn't push
them into the holes made for #14 wire).

If you stay consistent with your wiring, it'll be easier down the road when
you need to change out switches / outlets.

If your house was wired correctly - #14 Romex on the 15 amp circuits and
#12
Romex on the 20 amp circuits, you'll find that you'll have a hard time
getting the #12 wire to fit in a switch or recepticle rated for 15 amps if
you use the push terminals (and not the screws).

20 amp outlets and switches cost only pennies more than 15 amp ones.
Spend
the extra buck or two for the proper equipment and do it right the first
time.

If you find that you have #14 Romex on a 20 amp circuit - change out the
breaker for a 15 amp one.

All easy to do - but if you have misgivings or are unsure of things, have
a
licensed electrician do the work for you.

Hi again. I started a new thread because the old one was getting filled

up.
Below are my basic questions I would like answered if someone could
please
help me out so I know if I have to go back and replace some switches
and/or
receptacles. Thanks.


I have 15 amp rated light switches on a 20 amp circuit. These
light switches in most cases control overhead lights (in a kitchen,
garage,
dining room). Is this alright, or do I need to use 20 amp rated light
switches?

Also, on a 20 amp circuit, I have 15 amp rated electrical outlets? Is
this
alright? Some of these outlets are controlled by a 15 amp light switch
as
well, is that alright? Thanks for any help.
