32 amp shore power

To my surprise my new boat has a 32 amp shore power cable in the US on the boat side but came with one that adapts to the US 30 amp shore power. Was very surprised when I heard about this. That said, are there any ramifications for using a 30 to 30 amp shore power? I understand the two amp difference, however, if the dock side power can only supply 30 amps, how would there be a difference since you would never get the extra two amps?

Re: 32 amp shore power

Do you mean 32a inlet?

32a will be a 230v thing. So be careful plugging into 120v 30a...

Yes itís a 32a boat side inlet. They give you a shore power cord thatís 30a dockside and 32a boat side. End of the day, can still only draw 30a thatís being supplied shore side.

Re: 32 amp shore power

No difference, and if you actually GET 30 amps out of your shorepower it would be surprising, I've got a 30 amp plug but the marina ain't supplying 30.
Seems inconvenient to have that european plug, future cords will need to be custom made. I usually carry a spare cord to use at transient docks or connect the generator.

Re: 32 amp shore power

From a technical standpoint there is no issue with the inlet being rated higher. 32A inlet will carry anything from 0 A to 32A just fine and that includes the 30A the shorepower would provide.

The weird thing is that well the US is never uses 32A. The US (and most of Americas) is usually 30A @ 120V, 50A @ 120V, or 50A @ 120/240V split phase. Europe (and most of the rest of the world) is normally 16A or 32A @ 230V.

Now technically the plug being intended for 32A @ 230V usage doesn't matter if it is used in a 30A @ 120V scenario if everything on the boat is wired for that but it is weird.
As long as you are sure all the boat AC systems are 120V not 230V and properly wired then other than it being odd there is nothing wrong. Zero idea why a new boat would have a non-standard plug like that though.
