For the voltage drop calculation you should take load current which is actually drawn by the motor! Not the value used to rate your cable! Right?

@electricallectures Ай бұрын

Always find the values based on rated load as it keeps u safe

from which standard are the tables taken from?

@ajilmenon 4 ай бұрын

Hi..3.17.. No of circuits/phase means or phase?

@electricallectures 4 ай бұрын

Means number of total cables for each phase

@abhijithmurali9463 6 ай бұрын

I per cable = 194x1.25=242.5 right then how is it 238?

anyone know what documentation or code he is getting the different tables from?

@ianhowe1449 4 ай бұрын

The NEC (National Electrical Code) manual. I can look up the page numbers if you need em. The NEC is like 900 pages, but there are probably 20 pages you actually need to size any wire.

Didnt really understand that how at the beginning of calculations and without knowing the cable size, we can assume going for 2 multicore cables (after which we obtain 388A load current)

@electricallectures 4 ай бұрын

This is just supposition in order to calculate group factor. But if you keep foing calculation , you get a rough idea that how many per phase cables are needed to take the load. But proper way is to start by ond cable

@bheemashankark3380 2 ай бұрын

From where we can get those tables or references?

@electricallectures 2 ай бұрын

You can get the tables from cable manufacturer or you can download BS 7671 : 2008 standard pdf

What if the insulation is TRS?

@electricallectures 2 ай бұрын

Then another very critical factor also applies which is enclosed in thermally insulated material. In that case the factor is o.5 if the total run of cable on TRS is 300mm
