Powering up for largest Christmas show in UK

Contractor Stolworthy Electrical has installed the electrical distribution for the UK's largest Christmas show using Hager Invicta panelboards.

Hager's Invicta boards have been used for all the sub distribution for the museum and theatre lighting at the Thursford collection in Norfolk.

Outgoing ways of up to 250A provide circuit protection for theatre lighting and power.

Sixteen strand LD90 24 channel 2kW dimmers control the lighting.

Hager relays switch these TPandN power supplies at staggered intervals to avoid a mains surge in the plant room.

In addition there are forty intelligent moving lights which are protected by 16 A 30mA RCDs, which are also controlled by relays and timers in a staggered start.

All the control relays are mimicked with indicators in the Hager board extension boxes to show if there is a problem with any of the lighting.

These indicators are also on the main control switch for all the theatre lighting at the lighting desk.

The exhibition hall is turned into a huge theatre for the Christmas spectacular.

More than 130,000 people per weekend visited the show in December 2006, which had a cast of more than 100 professional dancers.

The site has now reverted back to a museum, which includes a traditional old-fashioned fairground where mechanical steam engines sit next to carousel rides.
