  • Grounding wire between distribution box and enclosure

    Grounding wire between distribution box and enclosure

    26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding an electrical panel is an important step to keep your home and family safe. However, it is always easy to overlook grounding aspects, or to fix them incorrectly. It establishes a dedicated, low-resistance return path for stray electrical current, preventing dangerous voltage from building up on conductive surfaces. Here's why it matters: Static discharge: Metal doors can build up static charge, especially in high-voltage environments. 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.
