    I've seldom seen these as I mostly do installation work, but does anyone know of any good calipers or gauge for measuring the csa of a cable?

    I use an ordinary digital caliper, now available for less than a tenner.

    Measure the diameter of the strands in a few places and take an average. Work out the csa of the strands, then multiply by the number of strands. Maybe write a lookup table for the common sizes.

    I use a micrometer, decimal one and do the Pi r² x the strands.

    I never found a pair that I found accurate enough, although I did only experiment with a few fairly cheap ones though.

    I made this, just one of Richard Burns many good ideas! :)
