Can use source ground return (SGR) earth-fault protection and residual earth-fault protection in micrologic 6 A/E/P/H together?

It is not possible to use both function at the same time because when you connect the sensor for source ground return (SGR). you are in source ground return (SGR) function only and residual is no longer valid.

The MDGF module is associated with 3P ACBs with external sensor adapted on the PE conductor. However with 4P breaker you can also use it but SGR concerns only the incomer ACB that means that the tie breaker should not use the SGR protection, only the incomers can perform SGR.
