Ground power options

My NL TC has a 3 pin plug on it with an adapter to fit a standard 15A socket. When removed, the plug is a 3 pin 30A type that will fit into the generator socket in the bay where the cable is stored. My question is, is this designed to be used exclusively with a 110V twist lock type outlet or can it also be used with 220V? There isn't anything that I can see that specifies. I am assuming 110V only, but thought I'd ask a dumb question in case it's not so dumb.

The reason I ask is I'm going to add an outlet on the side of my house and can provide either 110V or 220V. If 220V works and would charge faster that would be good to know. If I'd burn something down, I guess that might be good too.
  • 220V is just 2x 110V les with a ground and optional neutral. I assumed that my little 45A panel would have no use for 220V, but you've pretty much confirmed that.
  • Old-Biscuit, I really like the diagram you posted. Is there another one that shows the 50A rv connector??
  • NOTHING in a RV is 220 volts. A properly wired 50A RV outlet has two 110V hot lines, which if are properly connect, will have 220v across them. Each side is 110v ONLY to the ground or neutral connection. Each 110v side has a 30-50A breaker, which allows up to 50A on each let. There is NO increase in voltage. Trying to connect any 220V appliance across the two legs will only produce disaster. Many Campgrounds actually have the same 110V wire connected to both sides of the 50A connector, which will provide exactly the same results for the RV.
    However, as I am an registered OLD Fart, and it is common knowledge that many of us don't have any idea what we are talking about in the "MODERN" world, It is possible that some things may have changed, and I could be completely wrong. In that case I will not get my feelings hurt at all if some brilliant youngster that knows everything about everything tells you anything different.
  • 120V ONLY

    30A RV receptacle......
    1 HOT
    1 Neutral
    1 Ground wire

    Do NOT have it wired for 240V
    2 Hots and a 1 Neutral
    That will cause an 'electrocution' of ALL 120V components/and electronics in your TC
