When we first started PAT testing I had to unscrew the tops off
any none moulded plug for such things checks and change the
fuse from 13amp to 5 amp or 3 amp. Any plug without shrouded
pins was removed and replaced. I had a box of 100s of 13amp
fuses at the end, probbly still have them somewhere. Then the
lead was PAT tested using the PAT testing machine.

Modern appliances are all safe on a 13A fuse. Old ones not always.

But the fuse is to protect the cable not the appliance.

on recent stuff yes. Old stuff often really does need that 3A fuse if
it's to be safe.

But it has to come up to the recent standards that;s why you have tp
replace the cord

My 1937 mains lead is still ok & compliant. Many that age aren't of
course.

and check for earthing on antique light fittings, although I cna think
you can leave them as is providing they can't be connected up easily.
Or for specialsed places like museums.

Can be an interesting question how one can make noncompliant antiques
safe.

Feed mains through an isolating transformer ?
