How many grounding wires are there in the secondary distribution box
A 3-wire feeder consists of three conductors: two hot conductors (L1 and L2), and one grounded conductor that functions as both the neutral and the equipment grounding conductor (EGC). These panels are commonly installed in areas like detached garages, workshops, basements, or home additions to manage localized electrical loads. Electrician is also to wire in a second ground source, in case the main ground line gets cut. In a service equipment (main panel) and remote distribution panel (subpanel), the ground. A premise's wiring system supplied by a grounded service must have a grounding electrode conductor (GEC) connected to the service neutral conductor per Sec. 24 (A) (1) through (4): (1) General. The GEC connection to the neutral conductor at service equipment must be made at any accessible point. An equipment grounding conductor passing through the box without a splice is not required to be joined inside the box to others that are spliced in the box.

Requirements for grounding wires of relay protection devices
NFPA 70: National Electrical Code Article 250 covers the minimum requirements for grounding and bonding and, although the NEC lists requirements to abide by, it should not be taken as a design manual. A grounding terminal or grounding-type device on a receptacle, cord connector, or attachment plug may not be used for purposes other than grounding. (b) Branch circuits — (1) Identification of multiwire branch circuits. Where more than one nominal voltage system exists in a building containing. The conductor length between the SPD and the equipment being protected should be a minimum of 3 feet in length to allow enough time for the SPD to react. GFPE has been required for many code cycles for feeder and service disconnects rated 1000 amps or more and installed on solidly grounded wye electrical.
