If you are doing it, stop plugging in while the power is on. Turn a breaker either off inside house or inside your RV.

Attracts dirt leading to poor contact, overheating and eventually a meltdown.
Pedestals often have 30 amp recepts. in bad shape but you can't see inside them. They get a lot of abuse. If a one looks tired, crispy and/or has low retention force, use a 50 amp recept. (if available) with adapter pigtail or if no alternative, use a 30 to 30 amp pigtail adapter so if there is overheating and damage, you shore power cord will be okay. If a pedestal recept. seems loose, don't use it.
Always make sure your plug blades are clean.
Don't let your shore power cord plug get like this:
