30 amp =

This was, for the record, the most uninterpretable question I have ever read. I have no idea what is being asked here. I probably know the answer, being well versed in electronics and electricity but....

If nothing is "pulled" it is near zero. Is that what you mean?

The maximum is 120x20=2,400W for 20A plug.
120x30=3,600W for a 30A plug.
2x120x50=12,000W for a 50A plug.

The microwave is only going to be pulling amperage when it is cooking something. Otherwise the clock on it is going to pull a fraction of a fraction of an amp. If everything but the microwave clock and the light on the radio are off, I would guess you are pulling way less than 1/10 of an amp. But you are probably forgetting many other loads that come on when you plug in. Things like the battery charger, the converter, maybe the fridge etc. What exactly are you trying to figure out?

Power in WATTS is Voltage times Amperes.

If you simply plug in, and do not turn on any loads, you
are using 115 Volts times 0 Amperes = 0 Watts

If you add load, say 10 Amperes, you are drawing
115 Volts times 10 Amperes = 1150 Watts = 1.15 Kilowatts

This holds for a 30 Amperes rated circuit, but not for other
types of circuits.

wouldn't the microwave be about 1100 watts. the clock/radio/etc. minimal?
