Afternoon men (already bored of the football!)
for radials circuits that are to be installed as 100,101,102,103-table F6 is your friend!
but when it comes to ring circuits wired in 2x 2.5mm on a 32amp it always confused me a little!
-I know that 20amps per leg is the magic number- so the above example would be fine as 2.5mm ccc as 100 is 21amps
could someone point me in right direction as to where the magic 20amps per leg comes from pretty please
