Electrical Engineering
- Earthing connections - In a building, the connection of all metal parts of the building and all exposed conductive parts of electrical equipment to an earth electrode prevents the appearance of dangerously high voltages between any two simultaneously accessible metal parts.
- Distribution switchboards -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.
The principal types of distribution switchboards are:
- The main LV switchboard - MLVS
- Motor control centres - MCC
