30amp surge protector on 50amp line

Quick search here turned up nothing.
Am getting a new trailer. It’s set up for 50amp but doesn’t have the 2nd AC unit installed. Has the 50amp cord. Without the 2nd AC, I wouldn’t think that the RV would routinely pull more than 30 amps. My question is, can I use my 30amp surge suppressor or do I need to get a 50amp?

  • Due to the differences in wiring between a 30 amp cord/plug and a 50 amp cord/plug, you'd best be served getting a 50 amp EMS.
