I am going to do a Periodic Inspection of a large old restaurant, and whilst have seen that on a couple of the CU there are 100mA RCCB only. Will I have to insist that they are upgraded to 30mA? The system is TN/s.
I only ask as I know that the requirements for existing installations do not always match those for new installations and don't want to quote for work that doesn't need doing.
Thanks in advance,
Edd
