FactoryRegistry lists 1,437 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced surge suppressors, designed for equipment operating on 110-120 volt circuits (excluding industrial-use surge suppressors), 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.
