Conductor Size & Breaker Size

[trafficmike]

Good day all.

I am working on a roadway illumination project which contains some outlets on the poles. From my line loss calculations, I determined that I needed a #4 conductor. However, from the service cabinet breaker calculations, I determined I only need a 25A breaker. In the review, one comment was whether a #4 conductor can fit a 25A breaker. So, simple question, can it?

Thank you all in advance.

No, I dont think so. Your going to have to splice.

It depends on the breaker

But you really have me curious about what type of outlet you want to supply at 25 amps.

There are some reduction end lugs that would have on one end a female opening for the #4 and the opposite end is a stud that terminates at/on the
breaker.I can't remember who makes them or the actual name but I specified a bunch of them for a job a couple of years ago.
