We are required (by the standards, general morality, legal liability, etc) to ensure that products will remain 'safe' under worst case conditions.
Hence we spend much soul-searching to evaluate and to test under 'worst-case' conditions. Fuzing in most countries is generally via a 16 A CB or fuze - hence this is used for testing. It is pretty hopeless if the power cord ignites BEFORE the fuze blows - so check out worst case (high, and low voltage) and worst place for short-circuits to maximuze the current - AND to maximize the let-through energy. In the UK domestic plugs can be fitted with fuzes between 1A and 13A - some manufacturers supply plugs with a 13A marking AND a 1A fuze. PLEASE check that you do not use this configuration - these are potential fire hazards waiting to happen.
