Merlin Industries International Ltd undertook remedial works to Kirkwall Town Hall and the replacement of the 3 Phase distribution board in St Magnus Café Kitchens.
 The main part of the project was the replacement of a 3 phase distribution board in the busy commercial kitchens at St Magnus Café , within the town hall.
The existing distribution board was of considerable age and had been added to with numerous circuits and modifications. Due to overloading a number of bus-bars were burnt and the unit required replacement as spares were no longer available. Since the kitchen was in use 6 days a week, the works had to be carefully planned with the buildings management team to ensure minimal disruption to operations.
The kitchen was handed over to Merlin Industries Ltd at 16:00hrs on the Saturday and was completed and handed back to the customer at 08:00hrs on the Monday with all services fully operational.
The project had a number of complexities to be solved. Firstly the kitchen had 8 fridges and freezers in operation which required temporary power supplies whilst the works were in progress. The kitchen was carefully surveyed and measured and temporary supply cables and fittings were made up off-site ready for installation as soon as the kitchen was handed over. These supplies remained in use until the main distribution board had been installed and fully tested.
The second issue was the available space and existing cable routing. As can be seen in the pictures, the distribution board was required to fit in a purpose  built enclosure and had to match accurately the existing distribution board. In addition, a number of circuits had been added in SWA cable which were poorly terminated causing deformation of the existing distribution board enclosure (see left). Using our wide range of suppliers we were able to source a distribution board which fitted comfortably within the existing enclosure and had additional capacity if the customer required extensions in the future. The issue of the SWA cables was solved by re-routing and terminating the cables on a dedicated steel enclosure to ensure no additional strain was transferred to the distribution board enclosure. Additional cable trunking was also added to ease any future works required on the installation.
