Copper wire thickness - Less than 18 gauge a problem?

Im planning to use BJB holders and wire 1212's in series, however the spec states that the holders require 0.75mm copper cable.

spec sheet - https://www.bjb.com/index.php?pid=397936&lid=10

Most here talk about using 18 gauge(1.02mm)
losest I can get to 0.75mm is 21 gauge(0.71mm)

Im planning to run 5 cobs at 1ft apart, 50w each so 250w.
Mounting the driver within 5 feet of either end

I would of thought sanding down the end of the cable to make it fit is pointless, as it will no longer technically be 18gauge... I mite aswell just buy that 0.71mm cable.


Many thanks!

Ok, After doing some searching, it seems it should be fine to use 21 gauge. as that still has a rating of above 7Amps

If anybody has bjbs, what did you use? perhaps 18 gauge can even be pushing into the holder no problem?

This is really simple to understand-the conductor needs to be large enough to safely handle the current flow through it for the arrays. Once you have determined the correct gauge now all you need to verify is that the insulation around the wire can keep it from arcing. If those two parameters are met, then wire them up....
