If you have a lead with a 13A plug and an IEC socket (which is rated at 10A), surely the maximum rating of fuse in the plug is 10A as a large proportion of IEC inlets are not fused. A lead with a 13A fuse should, surely, fail a visual inspection?

Am I wrong?

I queried this with my supplier (as their leads are all supplied with 13A fuses). Their response was that it is to do with inductive loads and the associated inrush current. I cannot work this one out myself - surely a 10A BS1362 fuse would withstand the inrush of most 10A inductive loads.

If I install a 32A 60309 outlet on a wall - I have to protect it with a 32A breaker, regardless of the load (although I can choose the breaker type with respect to inrush currents etc). So how come these leads can be supplied with 13A fuses...?
