How far into the attic do you go when inspecting the electrical systems in a dwelling?
Can you see enough from the scuttle hole while standing on a ladder, or on the drop down stairs?
Sometimes under the insulation you may find serious hazards and defects such as broken cables, pulled out cables at connectors, open J-Boxes, and so much more. I have seen situations were the service raceway, that was passing through the area above the ceiling, was intercepted to get free electricity.
What have you discovered during the electrical inspection in these places?
