It's simple folks.
50 amps is a limitation...the camper may draw up to 50 amps...at which point the circuit breaker will trip.
The thing that runs his fridge and air conditioning is Voltage (pressure)... So with the a/cand fridge turned on...measure the voltage in one of the campers outlets. If it's normal...then that's not the problem...there would be significant loss over the line if the wiring weren't capable... If the circuit breaker is tripping...you can use a clamp meter to measure and record the peak amps...or simply swap breakers to make sure you don't have a weak one. Anyway, if his coach is tripping the breaker I would check for normal voltage... When voltage is low...the amperage draw goes up so the load can get the required watts to function. If that's normal...then the load in his camper is too high... IE maybe his compressors are going bad and pulling too high a load.
Sorry, WRONG. 50 amp RV service is a TOTAL of 100 amps.
As to the "misinformation" the fault of the RV industry. WRONG again. The RV industry uses the NEC electrical code as its basis. Blaming incompetent Electricians on the RV industry is wrong. Doug
Like you said 100 amps, two legs 50 amps each
When was the last time you heard a salesman, or a MFG tell a customer it's 100 amps of power , instead of the old std of 30 amps power
Unless specifically told people think 50amps at 120v
There is a great deal of confusion by the public aka consumers
The old 30 amp is configured and referred to like an outlet
Where the 50 amp is two legs like a residential service
NEC code is adhered too in doing the wiring
But the RV industry has never taken time to correctly inform the public
The 50 amp RV service can provide over three times the amount of power as the 30 amp service, most people don't understand that
They think it's only 20 amps more power used
They think if they leave one item turned off they can run on 30 amp adapter almost the same as when connected to the 50/100 service
So yes, I think the industry as whole is at fault for the buyer not knowing about his power usage and needs
A great many techs try too inform the user, but this is usually after the user has problems
