50 amp Shore Power, 30 amp on EMS

UFO Pilot Senior Member Winnebago Owners Club Workhorse Chassis Owner Join Date: Aug 2007 Location: Sonoma County, CA Posts: 2,163	This morning my 50 amp shore power suddenly went to 30 amp on the EMS panel. I have checked all of the breakers and measured the power thru the transfer switch at 240 volts. Any ideas on what to check or what the problem might be? __________________ Wayne & Roberta and Maggie the Miracle Dog 08 Winnebago Destination Gas UFO Tire-SafeGuard, Koni's, Scan Gauge II, Blue Ox, SMI Stay-in-Play, Winegard Travler http://travelinthomas.blogspot.com/

If it does not see 120/240 vac it defaults to 30 amp power monitoring. This may mean checking the neutral connection as well. Let us know what you find. Also give us the model of transfer switch and EMS.
