Low-voltage switchgear, designed, verified and tested.

Distribution boards, main and sub-main boards, motor control centres, standby-generator transfer panels, capacitor panels and busways. Boards are rated for a 400 V, three-phase, four-wire, 50 Hz system with insulation to 690 V, designed for hot, humid sites with a mean ambient of 50 °C and full humidity. Protection ratings are chosen by duty (indoor main boards and motor control centres at the higher level, sub-boards at the standard level) and raised for the site. Forced cooling is avoided because a fan failure creates hot spots; the exception is drive and soft-starter panels. A utility pre-approval regime requires the original design to be type-tested, the assembler to test the complete unit in its own name, and the supplier to hold a valid contract. We build to that discipline.
