WebIt is a leakage current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the associated circuit or the current exceeds the rated sensitivity. In RCCB, the ON and OFF positions are visible in its window, Green color indicates the OFF position, Red color indicates the ON position. MCB versus RCCB Webground fault relay is placed on the main, no ground fault relays are required on the feeders. Therefore, if the requirements of 230.95 do not require a ground fault relay and no ground fault relay is placed on the main service disconnect, then no ground fault relays are required on the feeders either (unless required by Sections 215.10 and 240.13).
