New Shore Power Pedestals sensitivity

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/

Won’t work. American 240v uses two 120v hots on opposing phases. N is not used

If you were to put a transformer to go bring one 120v hot to 240v you d have 240v across H to N. It would fry any US 240v appliance.

it would work in Europe where 240v is one 240V hot and N

Yes I think they do but way too expensive as a work around to avoid an issue with lack of 50amp

I have the system. Atlas will convert 50 Hertz to 60. It will balance and stabilize the frequency and voltage of the incoming power. With a boost transformer in series, the overall system will increase voltage as much as perhaps 40 volts, but of course as it does it requires amps to make the conversion. So if your marina is using a 3 phase transformer without the boost to supply the power, you'll be getting 208 and not 240. Atlas plus the boost gets you to 240, but your consumption perhaps doubles.

Atlas is a terrific system, but it won't get the 120 to 240. You'd need a special boost transformer aside for that to happen. That double of voltage is, then, a double in amps consumed. So your typical 30 useful amps of 240 would need a 60 amp supply to allow the boost to happen and be sustained.

Yeah, good way to ask the question. You can get boost transformers that will convert 120 to 240. Don't know that I'd feel very comfortable using them aboard on a regular basis, though.

My home marina uses a basic 3 phase transformer and provides 208v to the panel, and not 240. TO safely overcome the challenges and to not overly tax my onboard systems, I invested in a buck boost 208 to 240 transformer at the panel location. The unit provides my circuit with 100 amps of 240 volts, boosting the incoming 208. My issue was the wire run from the source was several hundred feet, and the voltage drop by the time it reached my Atlas system was at times below 100 volts per leg. When the local grid was hot in the afternoons and evenings during warm days, the voltage sagged. The power on board was almost useless.

The outcome was 240 volts at the main panel, up from 208. The voltage at the pedestal went up from 204 to 236. At my panel aboard, the voltage increased from 98 per leg to around 115 (230), and the boost aboard took me to my 240 without effort. My power consumption at the pedestal meter was cut by roughly 40%, but more importantly, I wasn't burning up compressors or motors.
