Today I found some broken insulation on my work lamp. To repair it I used heat shrink sleeves. This involved cutting off the sealed plug to get the sleeves onto the cable.
So, job done I had to get a new plug. I went to 'Robert Dyas' because I expected to get a quality plug. They stocked the plug seen in the picture below.
This plug cost £1.79. You'll see the plug has a 3 amp fuse. Had I wanted a 13amp fused plug it would have cost £2.49. Now according the 'Robert Dyas' site 3 amp fuses cost the same as 13 amp fuses.
So my question is, Why a discrepancy between 3 amp and 13 amp plugs?
