Out of interest, what's the usual way of identifying which cable is which once you've fitted this?
Do they do something like have a slight ridge on one side of the cable like with speaker cable, or is it a case of checking which cable is at the top and bottom of the lettering on the outer sheath, or is the easiest way just to test it?

Does it matter if it’s just. A switch drop ?

never witnessed it but heard if you look end on,
one core has an inner white sheath
one core has an inner white sheath
looking at twin red they both have inner white sheath
If theres enough sheaving exposed,before you strip it, you can use the embossed markings on the sheath as a referance, the core at the Top of the writing will obviously be the same both ends, then you can mark one prior to stripping back.
That sounds like hard work.
Be easier to buzz to the cpc if needed to know

Not necessarily both live all of the time. In the case of more complex light switching (with multi-gang switches), one might need to know which of a pair was the 'permanent live'.

When I have wired 2 switches to control one light. on off from either switch - hall to landing etc either wire can be live. That's why it was introduced. Before L & N was used - ok if you know it's that style of circuit.

You may want to connect the supply permanent live to the brown strapper.
You don't have to but I would.

Yes, if you use twin brown cable for the 'strappers' between two switches in a 2-way switching set up, then it doesn't make any difference which is which. However, as I said, in some other light switching situations you might need to know which of two browns in a 'switch drop' was the permanent live.

Always used twin brown. (Well actually twin red before it.) They're all phase conductors so should not be further identified. If you need to know which is which (not normally necessary except where you need to identify permanent phase) then simply bell it with one of the phase conductors to the cpc. Not rocket science.
