From my experience it's a 20A breaker that feeds the relay for load shedding and for 240V detection. J1 and J3 are used for 240V detection and for 2 20A load shedding appliances.
J6 is the power to the shedding relays, in and out.
J3 appears to be the current sensor.
On the attached electrical drawing I do not see any connection to the circuit board(EMS) to any breakers.
Here is manual for the 900
900 Manual
Yes I saw the Model 700 text below which is right below the Model 900 at the top of the page - go figure. Perhaps there are other questionable portions of the manual.
To insure proper operation of the source sensing circuitry on the 50 AMP EMS Model 700, jumper wires must always be connected from a Line 1 breaker to J6 terminal 3, and from a Line 2 breaker to J6 terminal 1. These connections must be made even though Relay 1 or Relay 2 may not be used for controlled loads.
J6 terminals
1 From Circuit Breaker for Relay 2 ( )
2 Output of Relay 2
3 From Circuit Breaker for Relay 1 ( ) 1 From Circuit Breaker for Relay 2 ( )
4 Output of Relay 1
