DIY systems usually require some cable crimped with lugs at the end. So this should be kind of common knowledge I guess.
I see two common pure copper tinned lugs and I'm wondering what are the differences.
The first one is usually designed as SC. I.e. SC50-8 is a 50mm2 (AWG 1/0) lug with 8mm hole in it. They look like this:
The other one is the JG. I.e. JG50-8. These look like this:
There are other types too. I.e. OT50-8. Like the one below:
I'm not considering the 3rd one at all. I don't think I would be able to crimp them with the hydraulic crimper I have.
Are there any major differences between the 1st and the 2nd (SC and JG) type? The JG type is more expensive and not so common. One advantage is that it is close-ended, so it may reduce oxidation and this can be a plus for car connections where dirt and salts may get to the lug. But I'm not sure if this is an advantage for DIY solar systems.
What's your opinion on this? Are there any preferred types of lugs?
