Dumb question re. hair dryer

1800 watts about 14 amps
RV AC about 12 to 14 amps
so, these 2 appliances will be about 26 to 28 amps
Your refer pulls 3 amps
Your Power Converter pulls about 1 to 2 amps
So, you will be operating just over 30 amps and will probably trip the pedestal breaker. just turn the AC to Fan when operating the hair Dryer. Doug

Will probably trip the breaker. We always run a 120VAC drop cord in from the 20AMP service at the camp ground pedestal for these high wattage things... It has its own separate circuit breaker and won't trip the the 30AMP shore power cable breaker.

Just don't use the max heat setting. Water/fridge on propane.
