    Whether it is a regulation or not ferrules must be installed on panel flex. This applies in particular to larger flexes such as 10 mm sq. as they are likley to be carrying a large current. If ferrules are not used the terminal screws often cut through the fine strands. In addition the terminals often loosen when they are not used.

    It is very normal to see ferrules on control panles from 0.75mm cables and above. The important thing is to ensure that the correct ferrule is selected. In other words, do not put a 2.5mm on a 1.5mm cable

    If your panel flex doesn't come loose he won't fail ya he doesent really care about ferules. Once it's fully operational, safe nd your test results are ok he will pass ya.

    Yea CDM. But reg 526.8.1 states otherwise and all regs are supposed to be followed. But I really doubt he will fail ppl over dat. Did you jus do the CDM.

    Also, many of the strands simply won't be well connected. MCB terminals won't have the problem of screws going through strands, but ferules are still a must.

    Operating simply based on what the rules say, rather than what electrical common sense says, in conjunction with regulations, is not great IMO.

    Well I wouldn't be putting them on anything except flexes. No point putting them on a 4 square SWA cable's terminations for example. Only on flexible cables with multiple fine strands.

    assuming thats the relevant rule
