I don't recognise that either. It sounds like a special case to me. And where do I buy a 16A fuse? > I've never seen one, but I would have thought a motor/generator pair > with a hefty flywheel would provide very good surge/spike/whatever > protection, and provide nice clean power.

Just think of the noise though, and the expense. -- Regards, Peter.
