Arrived onsite and the resident showed me the heat detector that matched the brand of smoke detectors they had installed into their home, build in 2022. He is getting solar done and they are requiring a heat detector to be installed in the garage for where the battery will be for safety reasons. I checked the Leviton panel and noticed the lack of whole home surge, which i went over the importance of especially with solar being installed, and double checked to make sure the smoke detector circuit was arcfault protected. I measured out the circuit and wrote him multiple options depending on whether the solar company wants permits or not, and one with the surge protection, which is the one i highly recommend. For today he just wanted to get some numbers because the project isn’t being done till June with solar so i am emailing the resident the estimates.
