To calculate the voltage drop of cable full load current need to be consider with length of cable, m/v/a of cable, nos. run of cable.

Answer / ameen

Thanks for ur response

I said same answer but interviewer told me we can take panel size bcoz if more than full load current flow in the cable panel ckt breaker will not trip(panel rating higher than full load current)at that time voltage drop calculation is wrong.

full load current is correct or panel size?

in ring main system we use the isolater b/w transfer bus and main bus if we r not use isolatar than wat will be the effect in our sys.
