Hi everyone
Has anyone ever used or have advice on using automotive cable like the below for power injection?
Seems like a good price for the length and cable size?

just be aware that even though it claims 4mm if you read the spec sheet it's actually 1.84mm2

It also claims it's 100m long and also 30m long, so you'd want to be sure about that.

Thanks Daryl, good pickup on the length. Found other suppliers with similar costs for 100m length and same cable diameter.
Would this cable be alright for power injection though?

I have no opinion because we don't know your use case. You would need to calculate how many amps you need to pull through it and the associated voltage loss. The suitability will likely depend also on the voltage of your pixels etc. There are some calculators on da-share.com to work this out. Alternatively you can just buy it and do the trial and error method.
