Today we removed ten single pole, standard breakers and replaced them with new dual function breakers. We also removed ground wires from the neutral bar and installed a new ground bar in the panel and landed there. There were romex wires coming in the top of the panel with no bushings around them for protection. This could allow metal to cut into them causing arcing and a fire danger. Romex wire coming across the ceiling and in the walls were not strapped properly and left dangling exposed to potential damage. There was clearly electrical work done after the initial house was built. Mainly the basement addition. The majority of the work around the panel for the basement was done incorrectly and very careless. There was clearly electrical work done that was not permitted, and would have failed any electrical inspection, before we made the corrections, this was a dangerous panel and should have been fixed before the home was sold.
