Merseytravel chooses Eaton for updating historic building
When it became necessary to replace the electrical distribution equipment in the Grade 2 listed George’s Dock Ventilation & Central Station of the Mersey Road Tunnel Building, Merseytravel chose Memshield 3 smart boards and MCCB panelboards from Eaton as key elements of the new installation.
Opened in 1934 and a widely admired art deco structure, the building houses one of the ventilation shafts for the tunnel and offices. The building is in full use, and a review identified that the electrical installation did not have sufficient capacity to meet current and future demand — and that the equipment was reaching the end of its useful life.
Replacing the electrical systems in their entirety presented a number of challenges. One was limited space for riser cables, and the risers not being aligned vertically. However, significant modifications to the structure were out of the question because of the building’s listed status.
That problem was addressed by using Eaton MCCB panelboards with removable cross rails so that cables could be laid into the board rather than fed through a gland-plate aperture — saving time and making installation easier.
For this project, Memshield 3 smart boards were used. They split power and lighting loads for easier metering, and these data are available to the BMS via a Modbus RS485 interface.
