in the past 14 months i have had to replace the 30A plug that plugs into the rv parks box at least 3 times because 1 of the prongs overheats and melts my plug. need ideas on what might be the cause
So the smart plug hasn't been certified by UL or UL marine and they make no mention of the one I respect the most, CES. It has just "met their (UL) performance requirements". It still has no NEMA designation and is not included in the NEC - unless I missed it.
