Whilst correctly conducting an insulation resistance test of a radial circuit supply a number of sockets-outlets, an unsatisfactory reading was obtained.
State 3 steps necessary to permit the remaining test to be carried out?
It is necessary to determine the voltage drop of a circuit where the length of the conductors cannot be measured on site and there is no reference information available.
State how the actual voltage drop for the circuit is to be determined.
Determine the actual voltage drop, in volt, if the combined resistance of the line and neutral conductors, at 20 degrees C is 0.45 ohms and the load current is 20A.
Hi All,
i have my 17th edition exam in two weeks time, the problem being i don't fully understand how to use the regs. any tips on how to use the book quickly?:confused:
