Arrived on the job site. The customer requested that I replace the Christmas Eve outlet breaker, which was originally a dual-function breaker. When I was here two days ago, the customer had purchased the wrong breaker, so today he provided the correct Square D QO GFCI breaker and installed it. After replacement, I restored power and verified that everything was functioning properly except for the far-left flower-bed lights. Those lights appear to have an issue either with the bulbs or with wiring between fixtures, as plugging them in causes the breaker to trip. The customer is 100% satisfied with today’s visit.
