Start with what is actually in the house
Visible porcelain knobs or tubes can be a clue, but old components do not prove that a circuit is still energized. The first useful step is determining what wiring is present, what remains active, and which areas of the home are affected.
Removal and replacement planning
Once the existing system is understood, the project can be planned around the affected circuits, access conditions, and the modern wiring needed for the intended use of the home.
Providence electrical requirements
Providence states that its Electrical Division oversees electrical installation, alteration, repair and replacement through permits, inspections and approvals required by law. Applicable electrical work should be planned with those requirements in mind.
