Grounding of metal strips in distribution box
Grounding of the units: Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Today, we're diving deep into the world of distribution box grounding, breaking down the standards, and shining a light on those sneaky mistakes that even experienced electricians sometimes make. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Without this connection, a fault could energize the box itself, turning a seemingly harmless component into a serious danger. During fault conditions, low impedance results in high fault current flow, causing overcurrent protective. This helps to reduce the potential difference that exists between conductive parts and the earth.
