I am installing devices on some new circuits in my house.
The circuits all have 12/2 wire and 20amp breakers.
If I install 15amp outlets, can I use these devices to bridge feed-in
and feed-out wires in boxes?
That is, consider a box that has two 12/2 wires, one feeding in and one
feeding out to another box. I could use the outlet to tie together
these two wires. Or, I could pigtail the whites and blacks and then go
from the pigtail to the device. The former approach where the outlet
connects the wires is easier, but I am not sure if 15amp outlets are
rated for 20amp pass-through.
(I know that a one-outlet 20amp circuit must have a 20amp outlet)
