You doing the sub mains? Hiow are you getting on with it? I am specifying 5 core SWA saves trouble on calcs as all cores the same size.

Yeah done the sub mains with swa used the table which roukel1 put up the measements are in ohms per km
same as mohms per meter.
Finished all calculations last night just got to do it neat now and do the research on pv inverters and the switchgear for the service room and the block diagram.

Hey Guys,

I am thinking of taking on the challenge of the 2391-20 qualification.
How are/did you find it in degrees of difficulty & time consumption? ~ Time being my least available commodity.

If you haven't got the time don't do it the project city and guilds say it takes 20 hours they are serverly lying.I must have done twice that and recon i have about 10-15 hours left on it.

with degree of difficulty I havent found it hard, just got to take a logical approach.

I found the project time consumming and trying to organise everything is time consuming as Kablue said.
As for the written exam! Even though it is an open book and you have 3 hours if you dont know the reg exepptionally well your in trouble.I found it twice as hard as the 2391-10 exam if not more even though i did pass.

Kablue where do you find out the grading of the exam? i only got notification i passed
