Current rating of waterproof connectors?

I use a heap of the waterproof connectors (purchased from Ray, but obviously available elsewhere as well), but just wondering if anyone knows what current they'll safely support - or is there an easy way of finding this out?

I would take a guess at around 5A, but that's only my gut feeling!

I can obviously ask Ray, but obviously you have to take what he says with a grain of salt.

If you have a micrometer, count the wire strands and measure the diameter of one strand.

I wrote a quick calculator to work out the cross sectional area:

Once you have the CSA, you can look up the specs in the ACL wiki:

I do have a caliper meter, but not sure how accurate it is - will give it a go tonight

Otherwise, might try and compare the strand sizes to a known cable size and go from there

Thanks once again!

Last year the maximum vurrent I ran through them was around 3.5A (on the return core of an RGB Item) without issues, but that was probably a little exceeding their real capacity. I believe Ray has said 2 to 3 Amps, to various people so I guess it is whatever you feel safe pushing them to.

For higher current items I have used Anderson connectors to power remote boards rather than run a lot of current through the 2 pin versions

It's worth counting and measuring the strands as the 2, 3, 4 & 5 pin ones had different sized cable when I chose mine last year.

Yeah, I think I only went up to around 3.5a max as well. My problem is that I like to use them for everything, to make setup as easy as possible. But no point running a 10A cable and then hooking it up to a connector that can only support 3A.
