So I was about to start wiring up my shorepower plug and it will take 8-10 ga wire. I wanted to go 8 for a little overkill but have noticed no extension cords that are over 10ga for 30amp 120v. I was going to make my own cord but I'm having a hard time finding twist lock ends. So my question is what are good ends to get for the cord or should I just do 10ga coming to the breaker box (inside bus) since the parks power is probably 10ga too. I'll hopefully be running a small fridge, TV, and Mini-split. Eventually I'll be throwing a genny on the back if we can't get power from our campsite (looking at the Predator 3500).
A 5-30 is the one you're looking for, 120 volt, 30 amp. L5-30 is twistlock. You'll need 10/3 SO cord minimum for 30 amps. A 6-30 is 240 volt and a 14-30 is 30 amp, 240v with a neutral . They're NEMA numbers and are universal
