Objective: Engineering, Construction and Start-up of Outdoor Switchgear Replacement


Project Summary

The Mercer 4kV Switchgear 21 and 22 Replacement Project involved the removal of two metalclad switchgear each housed in its own outdoor walk-in cubicle. The two switchgear units were replaced with vacuum breakers housed in Power Distribution Centers (PDC).
