Question 2 Blacks on (1 ) 15amp Breaker

HI, upon close inspection of my panel box I found 2 black (hots) wires connected to the same screw on a 15 amp breaker. The breaker controls the very first receptacle that was installed next to the panel box. Then it also controls receptacles in my indoor porch. Thus, those are the 2 black wires connected to the same breaker. Is this ok or should separate them? I have never tripped a breaker in 9 years so far. Ya never know whats under there until ya remove the cover. Thanks in advance.

Breakers are listed by UL. If the breaker is listed for use with more than one wire it will OK to have the 2 wires under the screw terminal as long as they are the same size. Square D for one is listed for 2 wires.

As long as the loads connected are less than the rating of the breaker and it is listed you should be fine.

If you try to run too much at the same time the breaker will trip. At this point you may want to separate the wires into 2 circuits.
