Using earth as a neutral.

i suppose you could have put a 1A in a FCU and fed it from a B6, saves labelling, prevents people from reading and ignoring labels.

I used to find that better in places where they could only read words to a max of 4 letters, and then they had to contain P, R, N and a vowel

Anyhoo, all wrapped up nicely in time for tea
