Lee Reynolds,

i dont understand your last statement! i too am a spark, and i personally run a split load board everytime i do a rewire, as a fullly protected rcd board can be a pain in the arse!

bulb goes in your bog in the middle of the night,,,, trip goes your 30ma rcd........alarm clock looses its time,,,,, fridge gets warm!!
believe it happens!

what if they wanna run a welder???? these have bad earth leakage's???

and your story about the metal light?? i always earth everything in the equipotential zone!

tell you a little story about a none split load board i fitted once (and last )

rewired a complete fish shop, with flat/home to rear and upstairs,,,, there was an old lady living in the granny flat on the bottom flor of the shop, the upstairs couple left there nan in her flat, closed there roller shutters, and when they was out there was an earth fault on there fridge ( second hand tight twats) this tripped the whole board out, the old lady was locked in for 8 hours as the old lady couldnt open the fire door,, couldnt manual the shutters, and couldnt reach the rcd reset
