Hi all,
I have worked out the volt drop on other questions using the formula mVxAxM.
had no issues, but this question below has just fried whats left of my brain, I have the answer because i got it wrong,
but how do you work this one out??
Being Dyslexic i do sometimes read the questions all wrong and am sure i am missing something simple here.
Voltage drop of a single-phase circuit supplying a bread oven is to be verified as part of periodic inspection and testing within a bakery.
The circuit has a measured R1+Rn value of 0.40 Ω and an Ib of 29.6 A. The circuit protective device has an In of 32 A.
The installation forms part of a public 400/230 V TN-S system. What is the calculated value of voltage drop?
a) 11.8 V
b) 13.5 V
c) 14.2 V
d) 14.8 V
