New Shore Power Pedestals sensitivity

A lot of home docks, transient slips or when boats are in for repairs will only have 30 amp service and often just one. It's not unusual, just inconvenient.

On my boat when I had to use 110v instead of 220v none of my panel meters worked (amps, Hz, volts, etc). I didn't think I even had power until I turned on some lights.

Sure you were turned on at all breakers? The lights are probably 12 or 24v so they're not telling.

Yes, I’m sure. Other items turned on as well and lights are fed from a/c.

Here in the Pacific Northwest we've been encountering this issue where marinas have upgraded their facilities.

Waggoner Cruising Guide - the cruising bible for these waters - has an article on this. To quote the article: "As marinas upgrade their facilities, they will be required by building code to add Equipment Leakage Circuit Interrupter (ELCI) ground fault protection breakers to shore power receptacles. ELCI-protected breakers are designed to ‘trip’ and turn-off power if an imbalance is detected between the power (amperage) going to the boat and returning back to the shore power receptacle. In the past, marina shore power receptacle breakers only protected wiring and cables from over-amperage. The new ELCI-protected breakers will trip, turning off power, if the boat incorrectly leaks amperage ortoo much amperage is consumed."

Here's the link to the article on their website: https://waggonerguide.com/elci-protected-shore-power/

They also have another article on how to prepare your boat to avoid ECLI problems: https://waggonerguide.com/shore-power-how-to-prepare-your-boat-and-avoid-elci-problems/

This is true in the US also except they are just called GFCI's

Nope. Single outlets, circuits are GFCI. The system protecting the entire shore power connection are called ELCI. They do the same thing, it's matter of terminology.

I stand corrected

Thank you gentlemen for an education. This is the first I've heard about ELCIs. ln my home I've got one line with 3 GFCIs on it. We had the microwave and coffee maker on that line and it was forever tripping one of the 4 breakers till I moved the coffee pot. Now on boats you'll have the GFCIs, along with an ELCI and then ELCIs on the pedestals and further down the line. Sounds good for safety but a nightmare for dockmasters and transient boaters.

What about some kind of transformer that would change the 30 amp (110v) shore power to 220 v for the boat end? I realize you would loose some amps but even 20 amps at 220 v would be OK

You'll be shortening the life span of your appliances IF you get away with it.

The only thing I know of that does that is a converter like an Atlas, the Atlas brand is very expensive.

I believe that an Atlas converter somehow changes any input into whatever output you need. (volts/frequency). Although I am not super knowledgeable on it.

Is there a specific 220v appliance or piece of equipment you are trying to run when you only have the 110v available? Maybe there are other ways to solve your challenge. You seem to realize you have limited amps regardless so this is what prompts my question.
