WebNov 24, 2010 · Hi snag, a type C has to have a much lower earth loop reading (50% lower) than a B type. For example a type B 32a would require a max earth loop of 1.15 ohm whereas the type C would require an earth loop of 0.57 ohm. You might be able to achieve the worse readings on some circuits but it is unlikely on a 40a mcb . Stick with the Type B.
