I have a 3300RLB with a 15k unit. when i start the ac, the voltage drops way below 100. sometimes the thermal breaker will trip on the ac before it gets up to speed, and sometimes not. the voltage before starting is at 120, and i was plugged directly into a 30 amp plug at the main panel. the voltage drops so low when starting that every thing else in the rv shuts off...tv, micro, satellite internet etc. if the ac manages to stay running long enough to get up to speed, the voltage will come up to around 110. i tried running it directly off my 4k generator with the same results so i am hesitant to think it is a power problem. it is a carrier air V.
