A/C work on 15 amp circuit?
Afternoon all! I have a 13,500 A/C unit in my trailer. The trailer power is 30amp. Is it safe to run my trailers A/C on the 115V 15amp supply at the trailer storage place? I don't want to run it for l...

Do you think I'd be OK using the 15 amp circuit?
Yes, it is. I frequently run my A/C off of a 15A circuit. I just plug in to the nearest exterior outlet at my house (side when parked, out front when preparing for a trip). I do however select the fan-only mode first and allow the fan to come up to speed before going to 'cool' and getting the compressor started. This reduces the inrush and voltage drop during those first couple seconds.
The scare about all of this is people using those cheap 16ga extension cords to reach somewhere, and are usually twice as long as they need to be. Running the A/C off of your supplied 'shore' cable is acceptable, but if you need a longer reach, a 12ga or 10ga (preferred) is required to reduce/eliminate the voltage drop that will be seen when using a lighter duty cable.
Remember, typical 15A circuit in your home is 14ga wire.
