The role of a switchboard is to divide the main current provided to the switchboard into smaller currents for further distribution and to provide switching, current protection, and metering for these various currents. Although this applies to all switchboards, the voltages and currents involved vary with the size of the application
Busbar systems are rated and certified up to 690V AC as standard but are usually connected to a typical LV network of 400V 3 Phase nominal. Neutrals are normally fully rated. Specialised voltages may also be used on some plants or offshore platforms.
Busbars can be supplied up to 6300A, at 25kA/1s, 50kA/1s, 50kA/3s, 80kA/1s and 100kA/1s. All systems are Impulse tested at 8kV
Automatic changeover systems(relay or PLC controlled)
Form 1 through to Form 4, Type 1 to Type 7. Top and bottom cable entry. (ACB’s normally bottom entry but can supplied for top entry)
Front or rear cable access
