hi everyone
i have a question on a shower circuit the ccu is a crabtree sb6000 type,tn-c-s system,100a main switch split load 6 way 4 protected by 80a 30mA rcd with shower 40a,cooker 32a not used,32a sockets for all house,16a old immersion circuit now used to supply 3 pir 500w...
Sorry to bring up an old post but im confused.
I have carried out tests on a kitchen ring final wired in 2.5mm/1.5mm T&E, results as follows:
r1=0.36 rn=0.34 r2=0.59
I then joined leg 1 of line conductor to leg 2 of cpc and leg 2 of line conductor to leg 1 of cpc and measured the R1+R2 at...
