Bristol Electrician; Electrical supply and circuits for swimming pool

Updated: Jul 24, 2018

(Bristol and Chew Valley Electrician) Back of the beginning of last year i installed the electrical supply and new circuits for a new indoor swimming pool. The first task was running the electrical light circuits in 1.5mm twin and earth thermoplastic cable back to the pump shed into th consumer unit. Next up was the electrical socket circuits in 2.5 mm twin and earth. The following job was running the main electrical supply feed from the outbuilding at the top of the garden down to the pump-shed, this cable was ran in 16mm 3 core steal armoured wire (S W A). I then installed a 10way consumer unit i.e fuse board in the pump-shed and then connected the electric heat exchange pump to the consumer unit. i used a 20 amp RCBO =Residual current circuit breaker with over current device. Then I connected up the non chlorinated circulation system. I used a 10amp RCBO for this, For the underwater pool lights for which I had to run a SELV circuit, which mean safety Extra Low Voltage, a 12volt transformer was used on this to lower the voltage from 240 volts to 12 volts. (12 volts would not cause any serious harm if live conductor was in contact with water or a persons body) The next step was to second fix the pools electric lights, we used a warm white L.E.D wall light which are specially designed to withstand water splash from any direction . The lights are IP55 rated which means ingress protection against contact with live parts inside the enclosure , protection against harmful deposit dust and protected against water from any direction. I used 6amp RCBO for this electrical circuit , there were electric sockets and fuse spurs installed for the pools boiler and other additional things and they was run off a 20amp RCBO. The last procedure was connecting up mains supply cable to a 100amp fused main Switch and then energised the main electrical supply. To finish the job off I tested all ring final circuits to make sure they where safe and within the regulation of the B7671 IET Electrical wireing regulations.
