Which code does this activity belong in?
Wiring device manufacturing covers establishments that produce current-carrying and noncurrent-carrying devices used to complete electrical circuits in buildings and equipment. This code is distinct from communication and energy wire and cable manufacturing, which involves insulating fiber optic cable or manufacturing insulated wire and cable; wiring devices are the connection points and fixtures rather than the continuous cable itself. Extension cords made from purchased insulated wire fall into all other electrical equipment manufacturing, not wiring devices, because they represent assembly of pre-made components rather than device manufacturing.
