FactoryRegistry lists 2,357 facilities whose primary industry classification is one of the 5 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced other electrical equipment for industrial use, including industrial-use voltage limiters, motor overload protectors, and surge suppressors (excluding for electronic circuitry), 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.
