GB-Poole: St Ann's Hospital, Main LV Switchgear Replacement

The hospital has a single 11kV 400kVA transformer sub-station supplying electrical power to the site via the adjacent main switchroom. The main Hospital LV switchboard is to be replaced with a higher rated switchboard having full automatic standby generator support, additional outgoing circuits and incorporating the existing SSE metering for the incoming supply and new metering for all main outgoing circuits to the buildings. The Hospital has many critical loads and hence the replacement of the LV switchboard is to be carried out in a controlled exercise, one outgoing supply at a time, with the installation of a temporary main switchboard supported from two temporary 400kVA standby generators throughout the duration of the disconnection of the loads from the existing main switchboard and their subsequent reconnection to the new main switchboard. The new switchboard is to be handled into position and assembled by the switchboard manufacturer's staff ready for the connection of the incoming transformer supply, the Hospital standby generator supply and the outgoing cables. The Trusts "permit to work" system is to be used throughout the replacement of the main switchboard.
