Hi: on a TT system what Ze would you use to base a circuit design on.
Where it says on the EIC Electrode resistance is that a standard test for Ze or is it the actual resistance of the rod.
If putting 2 ring mains through the same hole in Joists there are 4 cables and 2 circuits do you rate it as 2 circuits for Cfs
finally if half your circuit lenth is pulled through joists and half in plaster ie downstairs sockets is it C or what do you reakon
Cheers
