A friend has asked me to put in a new ring main in his new office and this has to be certified to be connected to the meter buy the power supplier. I have been told that as there are to be computers on this circuit it must comply to section 607 of BS7671. I have looked this up and it appears to apply to earthing requirements for the installation of equipment having high protective conductive currents. The computers that will be used are all notebook types so the only connection to the mains will be the chargers, so the question is will the circuit still have to meet 607?.
