Brand new 5er, and lots of questions

[Pocketlake1]

Here some of our questions-
When you turn on the AC unit (living rm), how many amps should it draw? We realize that once it is on the amps will back down, but in the start up cycle how amps are required?

Without knowing the make of the A/C and its output in BTU's, it's hard to provide you with an answer. A 4000W generator will be able to handle at least one A/C without any problems and perhaps two - depending upon how many other heavy draw items you may have on at the same time (water heater, microwave, etc.) After the A/C starts up, the amperage required drops, as you pointed out, to around 10-12 amps - depending upon a number of factors: outside ambient temperature, make/model, altitude, etc.)
