I always try to disconnect shore power to run the genset for 50 Hz when at the dock , but SM 243 has an automatic switch that preferentially uses the genset when also hooked up to shore power.

Alessandro,
check the postings on this site numbers 2888/9/0 dated May 2007, you will get wiring instructions and usage there.
Remember to disconnect the shore power when running you generator for 50 Mhz.

Hi friends,
I just arrived in USA from italy and I 'm falling crazy with tihe problem of the shore power:
As you know we have two problem: the volt and the hertz!
In the Marina I have : 110v 30 amp 60 hertz and 220 v 50 amp 60 herz.
I know I cannot use dish washer, clothes machine and microwave BUT , at least I would connect charger and air conditioner: someone said me I can connect ONLY 110v 30 amp OTHERs said me I could use 220v 50 amp 60 hertz . The MARINA said me don't connect 220v, I could break all my system becouse the 220v has 4 wires while european has 3 wires....anyway someone could tell me SURE whay I could use and how to put different wires in the US plug
Actually I had a plag with 3 wires : BLUE BROWN and YELLOW/GREEN and standard US plag has 4 wires: WHITE RED BLACK and GREEN.
my boat GRAND CRU is supermaramu 2k #443 with :
-2 Charger DOLPHIN 24volt 30 and 100amp
- air conditioner VECO COMPACT 9 EH
thanks for your help
