Hi, I have my AM2 next week and I'm unsure if i should be using the Max Zs figures from BS7671 at 100% or the On Site Guide figures at 80%?

Write the BS7671 values in the “Max Allowed Zs” box on the schedule of test results but compare your calculated (or measured) Zs results to the OSG values (which are the BS7671 values multiplied by a 0.8) when verifying your results before energising.

You can use either. Just add a note to say which one you used.

and maybe use the Ci factor to allow for when the DNO monkey is pedalling a bit slow and only generating 216V.

Cheers guys, I thought this was the case.
