Function of Double Grounding Distribution Box
The double earthing ensures the safety of electrical equipment and persons working on it. When lightning strikes or a rogue voltage surge decides to crash the party, proper grounding steps in like a seasoned bouncer, redirecting danger away from. e G” function of ABB SACE low voltage circuit-breakers. With this function it is possible to ensure protection against: − earth faults downstream the circuit-breaker on the secon-dary side of the Medium/Low voltage (MV/LV) transformer (unrestricted earth faults or downstream earth faults); − earth. Power from factory ground must be installed by a qualified electrician. 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. Next, we describe directional elements suitable to provide ground fault protection in solidly- and low-impedance grounded distribution systems.
