EMS 50C

[Richard Hayden]

Gregory,
On some older coaches the transfer switch is located within the inverter and
effects only selected circuits (outlets). Others, older coaches, the transfer
switch is outside the inverter but still only effect selected circuits. This
was because the older inverters could not carry the whole load and had to be
protected by selection.

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?????
