Customer called us out because her light over her garage door stopped working. After a troubleshoot I found that the light was tied to a photo cell on the side of the house. The photo cell had gone bad and the box was completely rusted. I replaced the box and the photocell. While inspecting the panel I noticed that 2 of the 15 amp breakers were sharing a neutral. I replaced the breakers with a 2 pole breaker so that both circuits have a common trip. I also installed surge protection and a ground ping bridge by the meter. Customer also had a light in her garage that the lightbulb had gone out in and she could not change it herself. I swapped the bulb for her with a lightbulb she provided.
