Hi,
To calculate the voltage drop of a cable from Appendix 4 of the IEE Regulations we use the following formula:
actual voltage drop = factor x load current x length
1000
My question is that i tried to solve some problems regarding the current capacity of cables from electrical installation books. It was said that a 2 kW heater at 230 V is installed 30 m away from the consumer control unit. I am confused about what length i have to take whether the 30 m or 60 m, the latter to take into consideration the length of the neutral conductor also. The book solved the problem with the 30 m length.
