Newbie! 30 amp to 20 amp converter

HI folks,

I'm brand spanking new to RVing.

The trailer I am attempting to make "usable" is a 1988 Companion Classic. Needs work.

My question: when using a 30 amp to 20 amp plug converter does it follow that a portion of the original 220 circuits will not work. Or does the adapter send current to both sides of the 220. I do not have the option of a 30 amp 220 connection. Only 20 amp 110. Some circuits are not working and I want to determine if this is normal or a malfunctioning adapter.

Thanks!!!!!

Rob

    Hi Rob,

    Welcome to the forums.

    RV's almost never use 240 volts.

    There are two legs of 120 volts each on a 50 amp rv service

    When using an appropriate adapter both legs will be powered.

    On a 30 amp RV there is only one leg and it is 120 volts. The adapter simply provides a way to plug into a 'standard' house outlet.

    NEVER plug a 30 amp RV into 240 volts or you may let out the magic blue smoke.

    I hope this helps.
