Hi again!
Which value is best to record in a certificate or report, a max measured or a calculated Zs?
I know Sparkies who do it both ways, but personally I take measured values at all the points of utilization to find the highest, then I calculate Ze+(my highest R1+R2) for the circuit and then I compare the max measured and my calculated values and record the highest of the two on the certificate.
Any thoughts?
