On the subject of the BG board, i am going to have to dispell the rumours that its made in the UK. Its fully made and assembled in china and shipped to B&Q in deliveries of circa 5k. I doubt that unlike more reconised brands the RCD isnt even tested when it arrives (gets shaken a lot on a month long boat trip)
The manufacturer is not actually BG but a chinese company and i suspect the same product is sold in the chinese market.
