Siemens, 20, Tandem Single Pole Type QT NCL-Circuit Breaker - 12 gauge cord is a touch tougher to paintings with however i've in no way had a whole lot of a trouble getting it attached to stores. (Working with the greater stiffness & bulk inside the junction box is the difficulty i have usually noticed.) But, perhaps you could select up a few 20 amp receptacles, even in case you don't assume using any 20a appliances? Glaringly a 20a receptacle needs to aid 12ga wiring.
I am working on a 20 amp circuit (with 12g cord of path). I'm connecting 4 receptacles each in their personal container, 15 amp receptacles for normalcy. However the terminals do not seem to simply accept 12g cord, even on the screws. My first response became to make pigtails 14g pigtails, in order that the 14g faucet goes immediately to the receptacle and is not used to feed the relaxation of the circuit. 12g in the field, 12g out of the container, and 14g in the box best.
A lot of these solutions are wrong. On 20a circuit, you could use #14 tails in the field to supply a 15a receptacle, however no longer a 20a receptacle. This falls under the faucet rule. But, if you're the use of the 15a receptacle as a feed-through (wherein the feed wires are on one set of terminals and the continuation of the circuit is on the opposite set), then they need to be #12 because they'll deliver the entire current of the circuit. All 15a receptacles are rated for 20a feed thru, but the receptacle itself will most effective allow a fifteen-amp device to be plugged in, so #14 is ok. That is the same purpose why #16 twine is authorized in mild furnishings.
Question is, why? Why use #14 twine when the circuit is already #12? Stay with what is there and hold the breaker 20a. In a few cases, such as in a kitchen, laundry or bath, you would be growing a violation doing it like you display in that diagram. Note on the returned of this 125v 15a duplex receptacle, it states that you could use 14 awg or 12 awg copper wire whilst terminating at the screw terminals, however that 14 awg copper should be used while terminating at the push in terminals. It also says that if you're the usage of the frenzy in terminal, and 14 awg copper, it may most effective be used on a 15 ampere circuit. If you're putting in this on a 20 ampere circuit, with 12 awg cord, you'll must use the screw terminals.
