G/046: Difference between revisions

The design also addressed the issue of electrical safety. The station would consume a great deal of power, especially running the lighting rig in the studio. There would also be substantial amounts of equipment thta must be kept running 24/7 as well as that which needed to be turned off when the station was not in use. An additional mains circuit was installed in the control room which was switched by an RCD near the door. This provided switched power for anything that was not needed 24/7.  The two circuits were sometimes referred to as temporary and permanent. In the studio, two rows of sockets were provided, each fed via their own 32A cable from the main distribution boards via RCD switches. Descending from the ceiling void above the rows were a set of mains plugs that were wired back to a series of sockets on the ceiling, used to power the lighting rig. No dimmers were available on the system (due to a lack of funds), so lights were switched on and off via the mains socket switches. Later a 2-channel dimmer fitted with 13A plugs was set up, but could only run a small part of the lighting rig. A proper dimmed installation was finally done in {{unsure|2002}} when a pair of 6-channel 30A dimmers were donated, which are fed from the 32A feed cables and used to feed the lighting rig via IEC patch panels.
