Hi,
In our meter cupboard we have a large switch box labelled B&P Controls BPDC 102PC. The switch has labelled positions Off, and 2. The switch is set to a third unlabelled position (meant to be 1?). Switchbox cabling consists of a pair of cables from the meter, a pair of cables to an isolator (and then on to the three consumer units), an earth cable and a bloomin' great inch thick SWA cable.
Last week I finally (after three years) got round to tracing the SWA. It runs to an open front garage where it terminates in a CU which feeds a 32A blue commando socket.
Not sure if it is relevant but the earthing is PME.
The whole thing was probably done in 1982/3 when the house was substantially altered. Everything looks like it was done professionally. My thought was that this is a transfer switch for plugging in a generator but why would it be a commando socket and not a plug? And why a CU? There is no other evidence of a generator, no earth rod, tie downs etc.
I'm not intending to do anything with it. I did some minor DIY home electrics back in the days when it was allowed, but I've not seen this sort of thing before, and I'm not about to meddle with switches and cables that size! This is more curiosity than anything. It's not causing any problems and I don't have any need to wire in a generator.
(Still trying to work out how to attach images!)
