    Purely theoretical question: What do you do when you have 6 * 1.5mm cables to fit in a heavy duty junction box that is only supposed to take 4 * 2.5mm cables?

    Eg.
    • Ring in
    • Ring out
    • Switch
    • Lights 1
    • Lights 2
    • Timer Extractor (3 core and earth)
    Do you
    1. Cram them all in? (Tight, but they'll fit)
    2. Find a bigger junction box? (Where?)
    3. Take a short spur off to another j/b for the lights (reducing the number of cables by one)
    4. Take a short spur off with 3 core and earth to another j/b where you can connect fan and 2 lights.
    5. Something else?

    :?:

    4 x 2.5 = 10; 6 x 1.5 = 9

    Hardly 'heavy duty' if it only takes 4 x 2.5.
