We should, given that manufacturers often (usually?) fail to include internal protection for the innards of their products. This is presumably why they often specify a seemingly irrationally low rating of OPD (like fans on 5A/6A circuits and wires with 1mm² cable requiring 3A FCUs). However, if they don't specify such a requirement, how can we know what is inside their machines, or what sort of protection may be required?If say the cable is rated at over 50 amps, and the fuse is 50 amps, and the appliance is rated at say 15 amps, should we be concerned how small the appliance internal wiring is?
