    if you remember the days when a petrol engine had a coil, the coil had wire coiled up to produce high amperage to deliver high current to the distributer.

    so leaving your hook up cable coiled up on a reel or not on a reel will produce the same affect

    it will produce high ampage and melt the cable after it has left the hook up point and NOT affect the mcb or the rcb

    Voltage drop is another factor for not using 1.5mm cable, especially if your further than 25m from the bollard

    Also, just because the breaker is rated at 16A, it does not automatically trip at 16.1A and can draw quite a bit more current before the breaker will trip on over current. Thus having the potential to overload the cable.

    I was a transformer fitter for many many years and when they did current tests on the transformer they used single wire 25 to 30 mm dia cables and when the power was turned on they were like snakes squirming around
