Transfer Switch Wiring Diagrams and EMS location choice - ac7880 - 03-25-2007 14:32 Transfer Switch Wiring Diagrams and EMS location decision: Mine is wired like figure B. In this setup, the invertor feeds all circuit breakers. If yours only feeds select circuits, then you are likely wired like figure C. This may help in determing where to install your EMS. http://www.iotaengineering.com/pplib/50rman.pdf Dan 94 BB BMC 37' NM --- In WanderlodgeForum@yahoogroups.com, "Gregory OConnor" wrote: > > Rob , then there must be a transfer switch for the inverter after the > shore - genset transfer switch and closer to the Wanderlodge power > fuse pannel????? > > GregoryO'Connor > 94ptRomolandCa > > --- In WanderlodgeForum@yahoogroups.com, "Rob Robinson" > wrote: > > > > My mistype Dan.

My inverter only feeds certain circuit breakers. For example it does not feed power to engine preheat or the water heater On 25/03/07, ac7880 wrote: > > Transfer Switch Wiring Diagrams and EMS location decision: > > Mine is wired like figure B. > > In this setup, the invertor feeds all circuit breakers.
