electrical 50 to 30 amp

When you utilize a 50 amp service for 30 amp RV you need to understand the supply breaker is 'not' protecting you. Note the 50 amp service has 2 X 50 amp breakers, that is 100 amps of power. A 30 amp service has 'one' 30 amp breaker. When you plug a 30 amp RV supply line into a 50 source you have a 50 amp breaker in front of a 30 amp service. So, that means 'no' protection for the 30 amp RV, at least at the source.

true, but assuming the interior breaker is working as should you still cant draw excessive amps through the supply cable into the RV
