ring reading for excample were l=0.36 n=0.36 e=0.56 r1 r2=0.93
Paul to be blunt..paperwork isn't an 'Arse covering exercise' you need to get to the bottom of what is WRONG this is potentially dangerous, investigate it and sort it

Your r1 + r2 reading looks wrong to me! Shouldn't it be around 0.23?
Wouldnt it go on the length of run?

Problem we have unlike the gas we don't have the power to turn off.
l=0.36 n=0.36 e=0.56
0.36 + 0.56 = 0.92
0.92/4 = 0.23 ohm
He's obviously not done the figure 8 .36+.56= .92 so he's added them together and put that down as (R1+R2)Your r1 + r2 reading looks wrong to me! Shouldn't it be around 0.23?

But you have the choice as to whether you should power it up, this whole thread worries me.

With additional proTection by rcd is in place then 1667 ohms is the highest zs, we have 6ohms here, that's 1661 ohms less that the maxium.....although that is totally unrealistic zs and should be investigated but even then the regs states anything over 200ohms. So he has done everything to bs7671 here.
