Dedicated line questions...

MC, that’s what I thought. Just seeing a variety of plug options etc had me wondering. Simple. Thanks!

@OP,

Hi there.

Domestic 15/20 amp circuits are a little more flexible than you are thinking. Kind of rare for the NEC.

The idea, I think is that you might want to plug in a couple of 10 Amp devices in at the same time, and that a single 15A circuit wouldn’t work.

As a result, you are allowed to use dual amperage receptacles, which have 1 prong shaped like a T on a 20 A circuit, and connect either 15 or 20 A devices or even far less.

Many devices, like wall warts, will sip off this and may be 0.5A or less. What is important is that the breaker be correct to the house wiring, and that the dual A receptacles be used only on 20 A circuits.

The appliances however may use any gauge of wiring that is acceptable to it’s own fuse/breaker rating. So yes, you can run a 20 A circuit, and put in multiple outlets with T shaped sockets and use 15 A surge protectors on them. If your appliance is rated for 15A you must use a minimum 14 gauge. If 20, 12 gauge.

Best,

If you want to get and idea how much amperage your component draws take a look at the ac fuse rating.

Bigger wires = better power transmission.
If you’re doing it, do it right.

Unless you are looking for mumbling.
