Not content with giving the world bangers and mash, black pudding and mushy peas, the English were at the forefront of electric motor design. The only problem is, some equipment still coming across our counter is the original English sizing, which doesn't fit directly with a NEMA replacement or an IEC equivalent.
Retrofitting has been around for ages and we are getting very good at subbing the old blighty equipment with a modern-day equivalent when required. The funny thing is, I know which of the two will still be around in 50 years with everything else being equal.
