My RV has an inverter prep consiting of a 30A 120V romex loop that I’m suppose to cut and use as input/output to an inverter. I have the 2x120 version of the multiplus II. Is it permissible to wire just the L1 sides of the multiplus - leaving L2 empty on input and output sides?

I eventually intend to run cable from the 50A panel splicing into the shore power feed, but don’t want to tackle that right away if I don’t have to.

Thanks in advance.
