Re: A/C unit

I returned to the job last week, and i was orignially incorrect. The unit did say Minium ampacity 16.6 A max fuse 25 A

my boss had me run a 10-2 romex with a 25A brk (rated for heat/AC)

I believe that it's legal to run a #14 with 25A protection.

If it actually said "max fuse 25A" and didn't mention any CB rating, then you must also have 25A fuses installed somewhere in the circuit -- usually in a fused disconnect at the unit. A CB in the panel wouldn't be enough.
