The Inventor of the Electrical Plug
Harvey Hubbell II invented the separable attachment plug — the device we call a power plug — in 1904 in Bridgeport, Connecticut. Before Hubbell's invention, electrical fixtures were wired directly and permanently; Hubbell's plug and socket system allowed electrical devices to be connected and disconnected, making electrical power flexible rather than fixed. This single invention changed the architecture of American homes and factories, and Hubbell's company grew to supply the electrical connection devices that the electrified American economy required.
Hubbell Incorporated is now headquartered in Shelton, Connecticut, and manufactures electrical wiring devices, commercial grade outlets, switches, and specialty connectors at US facilities. The company's 135-year history of electrical innovation, beginning with the invention of the plug itself, gives Hubbell products a heritage that no other electrical manufacturer can claim.
Hospital-Grade and Commercial Outlets
Hubbell's hospital-grade outlet line occupies the highest tier of the outlet market: products engineered for environments where electrical failure creates direct patient safety risks. Hospital-grade outlets must meet UL 498 specifications requiring higher retention force, more durable construction, and stricter testing than standard residential outlets. The green dot marking on Hubbell hospital-grade products — mandated by OSHA for healthcare environments — identifies these products visually, ensuring that the correct specification is installed in clinical settings.
The commercial-grade outlet line serves the broad market between hospital-grade specification and basic residential construction: office buildings, schools, retail environments, and any application where outlets will see continuous use and cannot be easily serviced. Commercial-grade construction means heavier-gauge internal components, better contact materials, and more robust housing construction than the minimum-specification residential outlets that dominate home improvement retail.
GFCI Protection and Wiring Devices
Hubbell's GFCI outlet products extend the company's quality commitment into life-safety territory: ground fault circuit interrupters protect against shock and electrocution in wet environments by continuously monitoring current balance and tripping within 25 milliseconds of a ground fault detection. The self-test function in Hubbell's current GFCI products automatically verifies protection capability, alerting the occupant if the protective mechanism has failed.
The wiring device product line — outlets, switches, and specialty connectors — is where Hubbell's 135 years of electrical product expertise accumulates. Every component is engineered to the commercial grade or hospital grade specification that the application demands, with the manufacturing quality that American electrical standards require. Harvey Hubbell's original insight — that safe, reliable electrical connection devices would be essential infrastructure for the electrified world — continues to define every product that leaves the Shelton facility.
