Cable Calc Template.

[JUD]

Good job Lenny.

Hope you don't mind but I added a few bits and pieces that I thought could be useful.

See what you think...

I like it JUD. I didn't see anything about ring final circuits though, or thermal withstand calcs for short circuit protection.Very good template though.

I like the clear layouts of both Lenny's and JUD's cable design templates

Just a couple of points

I would use U and Uo for the 3-phase and single phase voltages, respectively

JUD you have forgotten, in step 6, the Length of the final circuit being calculated.

Otherwise excellent stuff !

thts brilliant len, thanks

In step 6, do i have to multiply it by 0.001 to get ohms? i.e 4.91mohm/m x 9 metres x 1.2 x 0.001 = 0.053 ohms?


Or have i got it confused with something else, cheers mate

Yep or divide by 1000 (4.91 ÷ 1000) x 9 x 1.2 = 0.053Ω

It's all the same thing.

I enjoy doing cable calcs, so this is a perfect backup to make sure i'm always going in the right direction. cheers
