Make the connection between the grounding electrode and the equipment grounding conductor in a panelboard, junction box, or similar enclosure located either inside or outside of the
Chapter 6 Electrical Connections
The neutral bar must be isolated from the ground bar inside the main distribution panel or inside any junction box used in conjunction with the manufactured dwelling branch circuit or feeder.
Grounding of Services, based on the 2023 NEC
Some inspectors require the grounding electrode conductor connection to the service neutral conductor to be made at the meter socket enclosure, while others insist the connection be made only within the
Grounding
The enclosures of all switchgear, transformers, unit substations, motor controls and panelboards shall be grounded by a separate grounding conductor to the ground system.
NEC Requirements for Grounding of Services | EC&M
Some inspectors require the GEC connection to the service neutral conductor to be made at the meter socket enclosure, while others insist the connection be made only within the service disconnect.
DISTRIBUTION BOX
Each DISTRIBUTION BOX and controller must be grounded. On the US market, a 5.26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.
