To add to this discussion about the Genset AMP ratings. IF you have a Genset--and have a 50 amp RV and the Genset is a 5.5 or 6.0 0r 6.5 or 7.5 or 8.0. AND you also have a 50 amp EMS system. On Genset, the EMS amp shed system will start to shed the sequence of appliances if the RV goes OVER the amp rating of the Genset. Lets take the 8.0 genset that is actually rated at 67 amps. Once the RV goes OVER the 67 amps rating and tries to draw MORE amps than 67 amps, the EMS shed system will start to shed the selected appliances in the Shed order. That is why on Genset the EMS amp display still shows the amp draw. 10k and 12.5 k gensets will actually put out 2 phase current and disable the EMS system just like on 50 amp shore power. The EMS board knows what the amp rating is of the RV's particular Genset, because the installer sets it up on jumpers on the board. This can create problems when people replace the EMS control module and do not know to set the Genset load factor for their specific genset. Doug
