Ministry of Cake Switchboards

We were asked to custom design and build new switchboards to enable this manufacturer increase the power supply at their factory.

Brief

Ministry of Cake is one of the country’s leading manufacturers of UK produced hand finished cakes, puddings and desserts, producing more than three million slices of cake a week. They currently supply products to cafés, restaurants and pubs across the UK and Europe, including JD Wetherspoon and Hard Rock Café. They employ 400 people in Taunton and Torquay.

The power demand at one of the client’s factories was higher than the power available. These limitations meant that they has they had ‘maxed out’ their power supply, and had been using a temporary Generator running 24/7 in their car park to boost their power for months.

Outcome.

We designed three switchboards, all custom designed and built around the site circumstances. This included the Main LV Switchboard, installed into the purpose built brick LV Switchroom, built externally with a new supply provided to factory. We integrated our Switchboard into/with a Schneider Electric Free issued Intake Column which fed into our 1600A incoming breaker. The switchboard included provision for temporary Generator interlocked with castell keys (to prevent back feed and working on live parts), complicated metering and large MCCB feeds for loads. We also designed the Sub Main LV Switchboard and Yard LV Switchboard, both fed from Main LV Switchboard.

All Switchboards were delivered kerbside within eight weeks, and tested and commissioned by us on site.
