    5 yearly fixed wire testing

    A client is asking about fwt and they want 20% done each year, the building is now 5 years old, where in the regs does it state that 20% testing is allowed, as the grey area is the last 20% would then be 9 years out of date and not 5.

    Testing Supply of a Fridge..

    Hi there, I was testing the supply of a fridge with a voltage indicator. I tested the incoming suppy which was fine but when I tested the terminals on the compressor it tripped out the mcb. Why would this happen if Im using a voltage indicator and not shorting anything out as such? Thanks
