LV distribution upgrade
A dated distribution system replaced with a fully documented LV installation sized for the building's next decade — delivered over staged weekend shutdowns with the floor open every Monday.
Scope of works
- 400A supply upgrade
- New LV panel & sub-mains
- Power quality survey
- Staged shutdowns
The building had grown into its electrical system: additional tenancies, a new comms room and a kitchen extension had all been added to boards that were never designed for the connected load. Nuisance tripping had become routine.
A week of power quality logging established the real demand profile and identified a neutral carrying harmonic current well beyond its design. The design replaced the main LV panel, rebalanced the sub-mains and separated the distorting loads onto their own distribution board with a suitably sized neutral.
All works were carried out over staged weekend shutdowns. The building opened as normal on every Monday morning, and the handover pack included schedules, test certificates and as-built drawings.
