Shore power adapter TT-30P to SS2-20R 125V/3750W
RV 3-prong TT-30P male connector
Shore power for marine SS2-50 twist lock female connector with locking ring.
Converted my camper to shore type plug and opened up the hole bottom of the bathroom cabinet. The best part is I put the female end on the cord and now with this plug I can use any of my 3 cords to plug in. If one goes bad just grab another one.
Works great! Hooked it up to my Champion 3100w inverter generator to a 50' Mikelson yacht that has only 50amp plugs. Powered 3k watts just fine.
