Was called out to look at a microwave circuit tripping. Went to the panel to assess the circuit and upon my investigation noticed the panel was rusted and the neutral bar is corroding. There is also moisture build-up in the panel as well. I did not see any grounding in the panel which led me to look at the main water shut off and saw there was no grounding there either. I highly recommend getting the panel replaced as it is a major safety concern. This will entail replacing the panel, updating the grounding and bonding, assuring the home is safe from any potential risks that could happen as a result of an unsafe electrical system. Work performed today (11/20/23): Replaced the panel, updated grounding and bonding, and added surge protection. We will follow up to schedule the inspection and BGE. Thank you and have a great day!
