30 amp to 50 amp Conversion
My home RV parking spot was wired with a 30 amp RV service. My new RV is 50 AMP. I used a dog bone adaptor for a few days but wanted to run both AC's.
I noticed the that the 30 amp breaker was a double pole breaker. I removed the cover to find only one pole was being used AND there was an un-landed taped off extra wire. The unused wire was also taped off at the RV box. The builder had ran 10-3 W/G romex to the RV subpanel. Great. I had already purchased a 50 amp RV panel in anticipation of running another service.
I removed the 30 amp RV box and installed the 50 amp box using all 4 wires. I landed the unused hot on the breaker unused pole, leaving the breaker at 30 amps because it is still #10 wire.
I have created a 30 amp 220V service capable of 7200 watts as opposed to the standard 50 amp 220 service capable of 12000 watts. It is far better than a 30 amp 120V capable of only 3600 watts that I had.
I made voltage checks with the meter and plugged in the RV. I started both AC's and an amp check showed 13 amps on one leg and 15 amps on the other leg.
Does anyone see a problem with this? I do plan to run #6 wire but it will take some time and planning as it will have to be in conduit on the outside of the building. But for now all is working well. Heck, I may leave it that way if it never trips the breaker.
I don't see the need for 50 amps anyway. The generator is only 5500 watts and it runs both AC's. I am guessing it is a 20 amp 220 v service.
