1. Doubt the Transfer switch is bad. It is extremely rare for a transfer switch to only close 1 leg of power.
2. Your EMS senses the OUT OF PHASE 2 -120 legs of power. IF those 2 legs are on the same phase, the EMS assumes you have 30 amp service
3. VERIFY that you have double the line voltage between the 2- 120 legs at the 50 amp service pole(3 and 9 position). IF NOT, you do not have 50 amp service. But, "Cheated" 50 amp service. Cheated is a 50 amp breaker on the same phase supplying ONLY power on a 50 amp breaker and not a TOTAL of 100 amps which is true 50 amp service
4. EMS systems do not have to be "set" to 50 amp service. It is Automatic when connected to true 50 amp service. You cannot even change to 30 or 20 if on 50 amp service.
Do these tests and post. Doug

My Intellitec EMS sytem has a button on the left side to allow me to select 30 or 20 amp service, even if I am plugged in to 50 amp service.

From the EMS manual. Doug

NOTE When connected to 50Amp-240VAC service the Energy Management features of the unit are disabled and the Unit switches all controlled loads"ON".

Besides, if ON 50 amp serviced(100 amps) WHY WOULD YOU WANT OR BE ABLE TO SET 30 0R 20 AMPS????????????????

Good point BUT why did the manufacturer put the button there to switch input. Before I posted I went to my panel and I can push the button and change to a lesser input power than what I am connected to. Apparently the manufacturer had some reason to do this. If it is all automatic, no push button would ever be needed.

IF you would READ the manual it states WHY. To allow management when NOT connected to 50 amp If you are on 30 amp, it automatically uses 30 amp. IF you are on a less than 30 amp(Garage type plug) you can then set it on 20 amp. You may be able to push the button and change from 50 to 30 or 20 when on 50 amp, but it will NOT do anything. It may show 30 or 20, but as the manual states, ALL EMS functions are stopped when on 50 amp service. It locks the shed relay's closed. Doug
