Total amps don't match?
We just came back from Arizona. I thought winter was pretty much over so I decided not to winterize my View. But, Canada being Canada, a few cold days are among us. Last night, it went down to -8 C (14 F) and today, it is -6 C. I did not want my pipes to freeze so I decided to use my 1500W space heaters to keep the rig warm.
I cannot connect my rig to a 30 amp hookup. So I use a regular switch which is on a 15 amp breaker.
So if Watt=amp*volt, my 1500w space heater should only pull 12.5 amps, right? I assume that it would even give me a buffer for the rest of the usage of power (like the inverter/charger for example). So everything worked fine.
Then I tried to put another space heater (this time, using it at half is capacity). Is it 750W? I do not know. But it is still a fairly decent amount of heat. It continued to work just fine. I thought I would overcharge the circuit but no breaker tripped (I have two 15 amp breakers on that circuit, one outside the house, one in my main power box). How could it be possible?
