I was just looking for opinions on using temco 10 awg pv wire it is stranded but course,should you use a crimp ferrule going in to the dc breaker pros and cons.
It depends on what type of terminal is on the breaker. And how fine the strands are in the conductor.
If the terminal is a clamping type. No ferrule is needed.
If it's a set scew type of terminal. The screw can damage fine strands as it's tightened. And a ferrule will protect the strands from damage.
