What does the 6A mean? Is it only the obvious or is there something else?
Apart from the obvious and it is often stated this is the reason for the use of 5 or 6A OPDs on lighting circuits, is it really true that the terminals can only have a CCC of 6A?
The only occurrences of 6A flowing through a terminal block would be between the loop conductors in the live and neutral blocks on a fully loaded circuit at the first accessory on the circuit.
Fault current would be considerable more, of course, and presumably the block can handle this.
If 1mm² conductors are adequate for any fault current expected then presumably the terminal blocks must be as good or better than the cable.
As is apparent
the terminal material between the conductors is considerably larger than a 1mm² conductor which has a CCC of 16A.
Were we to put the loop conductors in the same terminal hole? would this remove the 6A limit?
What is going to be damaged should the circuit have, say a 10A OPD?
