A resi single pole 15A breaker trips occasionally when powering up a 120v chop saw. The HO wants to test the breaker, since this is the second saw that has done this.
1. Somehow find out what breaker make and model you have, e.g. SQ-D QO-115.
2. Find the trip curve from the manu's website.
3. Read that twice the rated current, 30A, will trip this SQ-D breaker in 8 to 27 seconds.
4. Put enough hair dryers, toaster ovens and incand. lamps on this circuit so the total is 30A.
5. If the (SQ-D) breaker trips in less than 8 seconds or more than 27 seconds, it's bad.
