Home / Grounding requirements for copper wires in distribution boxes
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. This Grounding Standard describes the technical requirements for grounding the SEC Distribution Network installations. 8 kV) feeder outlets of HV / MV Substations down to SEC Customer interface including KWH-Meters and meter boxes. Mistake: Thinking bigger ground wires are always better Solution: Match wire size to overcurrent protection—oversizing causes bonding issues with downstream devices. 7 Provide conduit grounding bushings, bonded together and connected to the equipment enclosure on all incoming and outgoing conduits on distribution switchgear and switchboards, distribution panels and on all conduits over 1-1/4" diameter at all panelboards, pull boxes and equipment.

Take reasonable measures to ensure that the resistance to ground is 25 ohms or less for typical loads. In many industrial cases, particularly where electronic loads are present, there are requirements which need values as low as 5 ohms or lessmany times as low as 1 ohm.
