Having done a few calcs then it seems that you cannot double the cores up on
a C type without using a RCD at the house end unless your Ze is much less
than 0.35.

I'll look into fuse alternatives but I do have to do some work as well!

Given that there never was a good reason for the C type, I suspect going
back to the B type will be easier, I've had no further email replies
from dad, so I suspect a visit at the weekend might be called for.
