    16, 32 and 63 as a rating

    Why are 16, 32 and 63 amps used as an MCB rating instead of 15, 30 and 60 amps? Best theory that I can come up with was when the UK switched to 230 volts this was to make up for the drop in voltage but have noting to back that up. Here are the ratings I'm familiar with: View...
