3 x Main Switchboard Supplies wired to AHF D/B's.

Wiring to an AHF D/B allows for future expansion of filters and requires only one Active Filter C/B mounted within the Main Switchboard. It also allows for servicing works to be able to be carried out on Active Filters without disruption to the Main Switchboard, as AHF D/B can be completely isolated at the MSB.
