hi guys,
Seen on the circuit details schedule in a DB on our site, someone had inserted Zs values for the circuits as follows.
16a C type breaker as 1.44 ohms
10a C type breaker as 2.30 ohms
80a C type breaker as 0.28 ohms
I believe he’s calculated Zs by doing (in the case of 16amp c type)
230/(16x10) = 1.437 and rounded up.
Instead of 218.5/(16x10) x 0.8 = 1.092
Who is wrong ?
