Powering camera

[bottletopburly]

I’ve ordered a new cable to go from my power box which is fused can’t remember what fuse I used need to look, but what size fuse should I protect with ? to my deepskydad hub which is rated 10a with a 4a resettable fuse , I’ve ordered a lynx Astro silicon cable 2.2-2.5 mm 1m , now from the DSD hub to camera power feed which is only about 12 inches away I usually just use those 2.1x5.5mm cables with the thin wire you get off eBay ones with the black and white wire will that be sufficient to use to power cooled camera or should I look for a cable with heavier gauge wire ? Obviously the tec cooler draws a bit of power tried last night using a cable with a car type fused lead which popped that fuse so I need to make sure cables and fuses are up too the job .

First check the camera maker's website for the power requirements.

That will determine what current the camera will draw, and hence the fuse rating.

Then look for what size cable is rated to take that current.

Thanks @michael8554

I know ZWO cooled cameras draw a max of 3A, I would imagine the draw of other manufacturers to be broadly similar.

Cabling is able to carry a surprisingly high current - decent 0.5mm2 cable is able to carry over 10A
