I came out today due to the surge lights not being on and a AFCi breaker located in the sub-panel on circuit tripping. The tripping 15 amp breaker had the deep freezer plugged into it and a furnace with lighting and other receptacles are on that circuit. I suggested to the homeowner to isolate these so that if the breaker trips again we will know what the issue is. The breaker for surge was in the “Off position” and when I turned it back on it had two green lights. The homeowners did inform me that they were playing around with the breaker for the surge and they also told me the freezer is around 28 years old. For today I turned the breaker for the surge back on. I dropped a new 20 amp circuit to a new box with a receptacle and plate. I also supplied and installed a. New plug on neutral 20 amp QO duel function breaker and labeled the circuit, tested and plugged the deep freezer in along with a unit that will sound an alarm if the circuit trips.
