Question AC electrical

[Old one]

Kevin: I know you can answer this.
On boats, the inpot power is (usually) a 30L5 or twist lock 30A.
On the pictures of RVs I see some of them, with a Clother Dryer type, "Y" plug forthe park end.Am I seeing this right?
The reason, I have a 50' 30 amp with 30L5s on both ends, andwent to make up input cables for home use for running battery chargers/maintainers, and fridge to allow set up the day before leaving, and A/C for while working on it. and possibly adapting my Honda 2000I.

That y plug has a different ground prong. This is a common problem with electricians hooking up campers to 30 amp 240v, not 30 amp 120v. You can make up a plug with twist lock but you cannot feed the 240 to the camper.

I have had at least 5 incidences where licensed electricians put 240 into a 120 camper. And other just look at the welding plug they have and assume it is the same. BUT, I will defer to the other Kevin as he is actually an electrician and has boat experience. Mine is just lobster boats and they dont plug into shore power.....lol.

A 30-L5 is a 115vac twist lock mostly available on generators for RVs?not so much. Your Honda 2000i has only 20 amp receptacles. A dryer Y receptacle has 3 blades for 220 vac without a common connection/wire.
An RV 30a receptacle has two angled blades one common and one line. And a post that is ground, and is designed for 115vac.

As for boats? The boat end of the cord is typically retained via a threaded collar. On one end the other end is not retained on shore so should the dock lines be worn through in bad weather. The cord has no way to be live should it be drug into the water. Nor will it pull the power post into the water. Boats typically smaller boats don't have 220vac connections ( a safety issue.)

I hope that answers your question. If not please clarify what you need an answer to.
