Install a residual current device RCD in the distribution box
Installing a residual current device (RCD) in your ABB distribution board is relatively simple if you're a bit tech-savvy. If an RCD is available in your laboratory, the instrument and peripheral must be included in that fuse circuit. Distribution board is a safe system designed for house or building that included protective devices, isolator switches, circuit breaker and fuses to connect safely the cables and wires to the sub circuits and final sub circuits including their associated Live (Phase) Neutral and Earth conductors. Therefore, an RCD exposed to such waveforms needs to be of a suitable type, otherwise a distorted waveform (or DC) could aff ect the time/current operation of an RCD and cause it to operate outside its correct operating characteristics – or, at worst, the RCD could fail to urrent. They can be found in fuse boxes, electrical switchgears or industrial machine control systems.

Each distribution box is equipped with a grounding device
Grounding device: to ensure the safety of circuit equipment grounding and prevent grounding faults from causing safety accidents. The design and configuration of the distribution box depends on the power demand and safety standards. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The grounding system provides a low-impedance path for fault current and limits the voltage rise on the normally non-current-carrying metallic components of the electrical distribution system. 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.
