FactoryRegistry lists 11,845 facilities whose primary industry classification is one of the 3 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced current-carrying wiring devices, lampholders, power outlets, precious metal, attachments, plug caps, connector bodies, lightning arrestors, and other miscellaneous current-carrying wiring devices, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
