Three-phase circuit for a ducted system
A whole-home ducted system in Enfield required three-phase power the existing board couldn't supply. We confirmed three-phase availability, upgraded the relevant switchboard section and ran the new circuit to the outdoor unit. Most of the housing on this side of Enfield is Federation and inter-war brick, so we planned cable routes and fixing points around that before touching a tool. 1930s wiring still lurking behind renovated interiors — inspection during any board upgrade is essential.
