Something that's bugging me and would like setting straight if you people would.....
say for instance you needed to provide a new circuit eg 20a and the customer has an old rewireable board with no room left. You decide to use a couple of henley blocks and split the tails just after the meter (all on 100a main fuse). You now have a 25mm line tail going into a single breaker enclosure containing the 20a MCB and onto your new circuit. Why does this 'second' neutral tail have to be 25mm? basically its just going to connect to a 2.5mm inside the enclosure.
I'm either missing something completely, such as the line tail nor the neutral doesn't have to be 25mm or is it that I've just set myself up to be mocked for being such a complete tool.
Customer has decided to go with a new CCU so this has now become theoretical but I got to thinking about it when I went to look at the job originally.
