I have an ATS (auto Xfer Sw) and need to add a control relay inside for switching status back to a SCADA system. What section of the NECA Labor Estm book should be used to install a DIN rail type relay with non soscket type, 4 pole. I used the MCC / Swich and Panelboard section, but other advise me to use building systems. I can not find installing a control relay / interpose relay anywhere in the NECA Book.
