as a former remodeling contractor I have found hundreds of poorly installed electrical fixtures, outlets, or whatever, O once gat a call to come out a nd finish a kitchen behind another contractor that had walked out on a job. he had taken the old panel which was behind the fridge, pigtailed to every circuit in order to in stall a new panel, then filled the entire old panel with drywall mud over the wiring and pigtails etc in order to finish the wall. I turned that job down, no way was i going to tie my name to that cluster in any way.
