Using 50 amp for 30 amp system
We only only have a 30 amp system in our MH, but I've bought an adapter when only a 50 amp connection is available in a park. Would there be any advantage to using the adapter and a 50 amp connection...

Hi Richard,
Plug in devices are not covered under NEC.
I have a "break out box" which I use. It contains one 30 amp female plug with a 30 amp breaker, and two 20 amp outlets, each with their own 20 amp breakers.
The #10 cord can't draw more than the 30 amps that the RV main breaker allows. That makes the question a "non issue".RLS7201 wrote:
I find it interesting that your 10 gauge cord, from pedestal to coach main breaker, will be protected by a 50 amp breaker. Always wondered how that fits in the NEC.

Maybe I should have been more specific. The 10 gauge, 30 amp cord is not protected properly. If the cord shorts out, then 50 amps can pass through the cord. That is an issue. That is before the RV 30 amp main breaker. Boom, bang, flash, fire!

As mentioned earlier, how is that any different than all the light 18-20ga zip cord connecting lamps, clocks, etc. to 15/20 amp outlets in your home? Or that 16ga extension cord you use outside to connect the hedge trimmer, etc. to a 15/20 amp outlet? An RV is basically just a large "portable appliance", although it does receive special attention in the NEC for the dual voltage systems, etc.
