Hi Mark, thanks for finding the notes, it saves me a lot of re-typing.
If anyone has queries please mail me and I will do my best to answer.
Typical wire current densities are 2000A per in sq or 3A perm sq. Plenty of wire tables about that you can work backwards to get the current for a particular metric or imperial size; it should be easy to do on an EXEL sheet.
Note that wires are rated as to their bare diameter. Coated diameters are larger due to 1 or 2 layers of coating (sometimes 3). Use bare dia for current and coated dia for bobbin fill.
Questions will also be answered on Sun at Golbourne.
