Riddle me this: my kettle doesnt use a kettle lead.
Have about 6 working all the time - lord knows why the fuses havent all gone pop...theres a 30A fuse on the mian feed line to make sure theres life in them yet i think.
Spares? Well its one with every case I buy, monitor, at least 2 with a part exchange system....I'd say I have 20 spares.
