Switchboard Design & Build

Distribution switchboards, including the Main Switchboard, are critical to the dependability of an electrical installation. They must comply with well-defined standards governing the design and construction of switchgear assemblies.

A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard. A distribution switchboard is divided into multiple functional units, each comprising all the electrical and mechanical elements that contribute to the fulfillment of a given function. It represents a key link in the dependability chain.

Consequently, the type of distribution switchboard must be perfectly adapted to its application. Its design and construction must comply with applicable standards and working practices. The distribution switchboard enclosure provides dual protection of switchgear, indicating instruments, relays, fusegear, etc. against mechanical impacts, vibrations and other external influences likely to interfere with operational integrity (EMI, dust, moisture, vermin, etc.) and the protection of human life against the possibility of direct and indirect electric shock (see degree of protection IP and the IK index in List of external influences ).
