The main bonding & supplementary bonding are all in place, but the earth on the garage circuit is dodgy (unsatisfactory); what would you do? Although you are only concerned with the circuit you modify, is it your responsibility to make other circuits safe too? Can this garage circuit be disconnected from the board with a danger notice attached or make a note about it on the Minor Electrical Installation Works Certificate ?Comments, if any, on existing installation? box. Re: What would you do in this case? If it's dangerous i.e code 1, and 1) is not the circuit you've worked on, 2) you've raised the issue with the customer, and 3) he refuses to take any action then I would issue and EDN for the affected circuit which requires his signature also and leave the circuit isolated. Remember though we have no right to disconnect or remove any faulty circuit it must be left so that if he wished he can re-energise the circuit after you've left. Issue a MEIW or EIC for your work and note the affected circuit details in the
