I have used the SB50's here for some extension cord type applications for high current cable pairs...
The problem I seem to keep having in a good way to keep them from pulling apart. I usually end up using tie wraps around both ends and then pull them together real tight. Of course doing this I have to snip the tie wraps when I want to disconnect the two connection pieces...
I really haven't looked on the POWERWERX site to see what they have to keep the connections together - Just reporting in my case they are pretty easy to accidentally pull apart.
They work great making cool to touch high current connections.
Don't know if others have this problem or not...
