Can you use a #10 wire in a 15a breaker?

[Cartoon1]

Hi all. I'm having voltage drop issues with a equipment that requires a 15ocpd, this equipment is far and I'm trying to increase the cable size to #10 to compensate for voltage drop. Is there any issues with running a #10 wire in a 15a breaker? Fitment wise and terminations.

Thank you

No. As long as the breaker can fit the wire. If not, a short pigtail and a transition to the larger wire will work.

Nope. As long as the lugs are rated for #10 at both ends. And if not just splice #12 to it.

And the EGC must be likewise increased. You mentioned 'cable' so you'll be okay there, too.
