Volt drop across 24awg cable

[chris_topher]

this cable is 7 strand 0.203mm diam for each strand, metal braided screened.

What would be the volt drop across 250 foot?



Great site!!

mv x Ib x L/1000 vold drop on a cable

mv x Ib x L/1000 vold drop on a cable

The above formula is for when the length and mv is in metres.

From you your question are you from acrss the pond?

Also awg cable would give that away. I'm afraid I don't know the formula for imperial and to be honest nor do most of the real world

24 awg is equivalent to 0.2mm csa!!!! Dont think our tables go to that dia. 0.5 is the smallest me thinks???

7 strand though, close to 7/029, so nearest eqiuvalent would be 2.5mm. diam. .s 0.2, so csa is approx. 3mm

"( how the f do you insert a smiley?"
I just type them by hand so to speak and the forum replaces it with a graphic.
