Shore Power

[snotdoc]

2022 G23. We have always used the 110V plug in for the battery minder at the marina. They sent us notice that we have to use the 220V plug in instead for the boat. I am unable to find in the manual if that battery minder can handle 220V or if I need to get a converter. Appreciate any insight

220V...this makes little sense.

Agreed with srock, who's brain child was that?
What, Prius making boats now?
Step down converters (220 to 110v) aren't that expensive, if you need to go that route...

They're probably getting ready for that wave of EV boats that consumers are dying to get their hands on.

Shore power at Marina's is almost always 240v. Shore power is typically used by larger boats and they pretty much always require 240v. I suspect the Marina just doesn't want to maintain both outlets and wiring any longer. In which case, 240V is what you'd have to support.

Your battery minder is required to have a voltage spec on it in order to be UL certified. Just find the label on the device. You may have to unbolt it to get a good look at it or if the label is on the back.

Some new government official in the great state of Oklahoma made this their priority. No known reasonable explanation has been found. Unfortunately very typical for Oklahoma.

By golly, they make a 220v to 110v pigtail. Problem solved. 240v to 120v if your not stuck in the last century like me.
Look at the wire bank on that, it looks like a common ground and neutral, then one leg hot for 2 plugs on the right, and the other hot leg on the left 2. Not bad...

Most common receptacle used at Marina's is a 3 prong twist lock. There is no neutral, so you can't use an adapter like that. If they do use a 14-50 receptacle, then you're good to go. But I suspect, they are changing to 240v to simplify the arc fault and ground fault requirements for power distribution around water. If that's the case, they specifically won't provide a neutral line to the dock power boxes. Because that's defeats the purpose.

Any confirmation as to 3 or 4 wire 240v snotdoc.
Care to offer a solution jpwhit?

I had a boat with 2-30 amp 120v power cords (house and A/C) but I would often run into marinas with a single 50 amp receptacles. I had a Hubble marine cord that would split the 50 amp into 2 lines that I could plug into. Look around, Amazon, any boat, RV, or even etrailer carry a bunch of different plug conversions that will get you something usable for your trickle charger. You just need to know what receptacle the marina will deliver so you can find the correct solution. My hunch is it will be a 50amp receptacle unless the boats are over 40 feet. The key was to always check the receptacle at the dock with a tester because you could often find some sort of power related fault.

Check if current charger supports 240v

If not, install one of the following.

Why not just use a step down converter, a whole lot less money, and you can still plug into 120v when the boat comes home (I get you can still run the Mariner at 120v)?
Not to mention, without the pain of having to change out your current charging system.
Just messing with you JP, sorry Bud, always appreciate your knowledge and insight.
I liked srock and his Hubble Cord suggest, doable if the Marina will allow it...

Hmm, let's take our waterproof and spark protected marine charger and run that through a cheap step down converter with it's fake UL sticker, and then connect that to the Marina's arc fault and ground fault rated power system.

So, to sum things up, your best advice seems to be:
1) Find a manual for your charger/maintainer and see if it'll work.
2) In the absence of said manual, contact the manufacturer.
3) Buy a new charger/maintainer that will work with the marina's electrical system.
