Is it OK to mix 15A and 20A receptacles on a 20A circuit?
Suppose I put a 20A GFCI as the first receptacle, and put 10
15A non-GFCI receptacle downstream, protected by the 1st
20A GFCI, will GFCI will be effective?
What about we put 1st as 15A GFCI, followed by a mix of 20A
and 15A receptacles protected by 1st GFCI. Will that cause
Are they code vilation?
My builder put 1st receptacle as 15A GFCI, protecting a few
non GFCI 15A downstream in the kitchen, in several of 20A circuits.
So using 15A all the way through a 20A circuit is OK, I suppose.
Hopefully it is a 20a circuit, or you would not be asking this question,
Then, yes, you mix and match. However, unless you have a really good reason
for doing so, don't bother with a 20a GFCI. They are more expensive, and
you are unlikely to find anything to plug into them.
Electrician told me the code now requires use of 20 amp GFCI. He also told
me it's ok to mix and match 15 and 20 amp outlets on a 20 amp breaker. Since
the 2nd outlet has current supplied by the copper pieces on the side of the
previous outlet, I'm assuming the through current rating of a 15 amp outlet
is 20 amps. Is this correct? Or should each individual 15 amp outlet have
pigtails from the supply line that go only to that outlet? For the small
difference in price of only $1.39 each, why skimp on 15 amp outlets on a
It is possible that your local code does require a 20a GFCI.
There is no need to pigtail, though some people think it is a better way to
run circuits in general; yes, outlets are through 20a even if they are 15a.
(The pigtails obviously have to be 12 gauge)
I "believe" there is no difference between a 15a outlet and a 20a except the
slot direction. It is purely to prevent you from plugging a 20a device into
a 15a circuit.
I haven't bought a 20a GFCI in over a year, maybe they have come down in
price; there is certainly no harm in using 20a outlets. It is just unusual
to see a 20a plug. (I have one on my 2hp table saw, but thats about it.)
With the exception of a window air conditioner, is there any reason
you need 20A outlets in a home? I have never seen a need for them
using any home appliances. The only other exception would be if you
have a home woodworking shop. I only use #12 wire, on all outlets, so
I can always change the outlet and breaker, but I have never seen the
need. I only use #14 wire on lights, and often use #12 there too.
Just depends on what I have on hand. I always use a 15A breaker on
Code requires that, on a single-outlet 20a circuit, the receptacle be rated
20a. IF you have a 20a circuit with MORE than one outlet, you may NOT use a 20a
rated outlet in configuration, but may instead use 15a rated devices.
