Commercial-grade 50A receptacles, such as the Hubbell HBL9450A, are recommended by a leading electric vehicle manufacturer for electric vehicle supply equipment (EVSE). Unlike standard 50A range receptacles, which are typically used for only 1-3 hours at a time and made of less expensive materials, commercial-grade EVSE receptacles are constructed with more durable plastics and single-piece contacts. These features help dissipate heat during prolonged charging sessions.

The Hubbell HBL9450A is specifically tested for ten hours of continuous load, a scenario common in electric vehicle charging. In contrast, using standard range receptacles for this purpose can result in melted components, reduced charging amperage, and even serious hazards such as electrocution or house fires. "It’s not difficult to find images of these melted range receptacles on the internet," notes an industry expert.
