If you have a 50 Amp MH, plugged into 50 Amp service the EMS will not show anything. Not needed.

This statement is not always true.

These pictures were taken a 3 days ago, when the OP made his original post about this issue.





Both AC were running, when the pictures were taken.


Per wa8xym's post, perhaps my ems has multiple sensors.

YOUR system is a PCI brand system and will show amp draw on EACH leg with a total. But. the OP has a 30 amp RV and is 13 years old and PCI was not in business back then and the OP should have the Intellitec EMS system(Winne used that back then as well as 90% of OEM's). The Intellitec does NOT show amp use if on 30 amp service(30 amp system) or 50 amp if it is a 50 amp RV and is on 50 amps. You do have multiple sensors(2). The amp draw is taken from the current running thru the EACH 120 hot leg. There is a "donut" that the RED and Black lead runs thru and the PCI senses the current thru those 2 donuts. Intellitec systems read the current thru just the single NEUTRAL lead thru the same type donut. The advantage of the PCI system over the Intellitec is simple. Intellitec EMS system IF it fails or malfunctions, NONE of the appliances connected thru the EMS system will have 120 to them. PCI designed their system, if it fails, then the relays stay CLOSED and you have 120 power to all appliances on the EMS system. Doug
