just had a customer in the phone saying that an engineer refused to work on her broken dishwasher because of a failed earth loop test and no rcd being present
The setup is as follows
Tt supply
From the House consumer unit a 10mm twin and earth runs through the house buried in the wall following safe zones etc into an enclosure where it changes to swa and runs under ground into the garage terminating in a 2way garage cu with main switch which feeds a 32a socket circuit and a 6a lighting circuit the dishwasher is plugged into the garage socket circuit the submain is on a 40a mcb protected by a 30mA rcd,
The rcd has been omitted from the garage cu as the submain required rcd protection due to the cable route and being a tt supply
He is saying there should be an rcd in the garage cu ?? I say no for discrimination reasons, does he know something I don't ?
Thanks
