We came out today due to some lights flickering in the home. The areas that were effected was in the kitchen (1) light bulb flickering on and off then would stay on after awhile and then repeat. The other location was in the master bathroom for the sconce lights and a couple of these bulbs were very dim or not working. The customer stated that she took a surge last year and lost a tv which was replaced. She also stated that she had a surge protector installed at the panel. We went to the panel and removed the cover and found the Eaton Micro Surge installed inside the panel on a 2p15 CL breaker. I checked the condition of the grounding electrode system for the home and noticed that it was utilizing a UFER (Concrete Encased Electrode) which was located to the bottom left of the panel behind a 2g plate. After removing the plate I found where a #6 bare copper wire had been installed which is a violation of 250.52 (3)(2) and should be a #4 bare copper conductor. We informed the homeowne
