Have you ever wondered why the information label or rating plate on electrical equipment always gives the number of watts or kilowatts that the appliance will use, but rarely tells you what size fuse to fit.

After all, we choose fuses in amps not in watts so how are we to choose the correct size fuse.

A fuse should always be chosen for correct function and amps rating; it should be just big enough to carry the loads of the circuit but not too small that the user complains of nuisance tripping every time they turn the appliance on.

A fuse should also be the correct size for the safety of the occupants of the building.

Too large a fuse size and it may not trip effectively under certain fault conditions.

So, in this video, we will show you, in very easy steps, how to calculate the current consumed by the equipment from the rating plate and this will allow you to make the correct choice of fuse for fault protection and safety.

A simple formula that once learnt, should never be forgotten.
