installation of new new devices located in the garage and front of garage. Devices currently are older and show signs of failing and currently not working properly. We also discovered two outlets that were reversed polarity. Most devices are housed in metal boxes with no protection from being grounded out while being energized. We will replace these devices and correctly protect each device when being reinstalled. We were called out today to look at a receptacle that sparked and caused the circuit to not work. While assessing the circuit we discovered many of the devices were original to the house and were not wired correctly. We gave solutions to replace the devices and correct the wiring, as well as the installation of a surge protector in the panel, panel corrections, and the installation of LED bypass tubes. Customer went with the solution to replace the devices, and was interested in the installation of a surge protector in the future.
