  • Thickness of grounding terminal block in distribution box

    Thickness of grounding terminal block in distribution box

    Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding of the units:When you're building an electrical panel, a grounding terminal block is one of the most vital safety components you'll install. It's the central hub designed to safely channel dangerous fault currents away from your equipment and, more importantly, away from your personnel. Linergy terminal blocks have push-in type, spring type, and screw type terminal blocks. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the. The core difference: a ground terminal block creates a direct, low-impedance metal-to-metal connection between the conductor and the DIN rail (and therefore the panel enclosure), while a standard terminal block keeps conductors electrically isolated from the mounting rail.
