    I maintain an old established holiday chalet park with about 80 holiday chalets. The main intake room has 3 X 200 Amp main fuses. I suggested that the supply be upgraded as many chalet owners are installing new electric showers, cookers, ovens, grills, and heating etc. There have been no major fuse blowing issues reported due to overloading. I did once change  an old M.E.M. switch fuse due to old age, minor wear and rust.

    Some of the sub mains are protected by old hot wire fuses.

    I can only assume that luck plays a great part in having no regular fuse blowing. The fact that everybody does not have a morning shower at the same time. The fact that the park is never fully occupied. The fact that most people eat out whilst on holiday, and that the park is only open from April to October must contribute as well.

    The park is fully electric with no gas or gas bottles at all.

    I do feel that some remote chalets may suffer from high Voltage drop with heavy loads.
