FWIW you can use 15 amp receptacles in a 20 amp circuit as long as there’s more than one place to plug in on the circuit, in other words, a dedicated receptacle. It’s good to use 20 amp receptacles in shop areas since that’s the only place you’re likely to find a need for the ability to take a 20 amp plug. Not a bad idea in the kitchen, too, since the 20 amp ones are a bit more robust, even though I can’t think of a kitchen appliance that has a 20 amp plug. Most electrical contractors would be using 15 amp receptacles on your 20 amp circuits for reasons of economy. We won’t talk about commercial grade vs residential grade switches and receptacles.

The internals of a 15amp receptacle are 100% identical to a 20amp receptacle. There is absolutely no reason to use a 20amp receptacle unless you have or plan to have an appliance that needs that plug type which is HIGHLY unlikely.

Most homes use 15 amp wall receptacles with a 20 amp circuit breaker. Most 110 volt Window Air Conditioner come with a plug requiring a 20 amp wall receptacle.

Not to be argumentative, but you'd be hard pressed to find a window A/C with a 110v 20amp plug. It is by far and away the exception versus the rule. In fact, I just did a cursory search of units up to 15k btu and can't find any with a 20amp plug.

None of the AC units you linked to have 20amp plugs. Typing something into Google and getting results doesn't make it true. Actually click on the AC units and you will see they all have standard 15amp plugs.

Are you trying to say that none of the units use a 120V 20A plug? That may be true. Most appear to be 240V units. I pulled up Gator's Google search and went to the 'shopping' view of it. 4 of the 5 units I looked at (all of them that I could find plug info for) said they use NEMA 6-20P. That's a 20A 240v plug. So yes, it is 20A, but it is not the 120V 20A style. You may both be 'correct' but just not talking about the same exact subject.

I like to use 15 amp lines for the lights and keep them separate from the 20 amp lines for my outlets.

My preference too. The wires on light fixtures are so tiny and the space is often so small to work in that the smaller size and extra flexibility of 14 ga helps a lot. Plus nowadays with LEDs drawing so little power, a 15A circuit goes a loooong way on lights.

Plus when you trip a breaker (usually due to something you plugged in) the lights don't wink out too!

I like those cabinet levelers ! I assume you have finished toe kick panels to install as well ?

Did you think about trimming out the windows before installing the cabinets ? Going to be a bit more of a headache now with the cabinets in the way. Nice work as usual from you guys !!!

Correct. Units above 15k BTU are 240v, not 120v. The discussion was about 120v circuit wiring and receptacles and there are simply no 120v AC units that use 120v 20amp plugs.

We took this thread off-topic though, my apologies.
