FAQ

Q: Can I run both air conditioners on this adapter?
A: You will typically need to manage loads carefully. With only 30 amps available, running multiple large loads at once can trip the pedestal breaker.

Q: Does this change my coach from 50 amp to 30 amp?
A: Your coach is still wired for 50 amp, but while using this adapter you are limited to 30 amp service at the pedestal.
