Hubbell 4730 Locking Connector Nema L5-15R 15A 125V

Product Description

The HUBBELL 4730 is a locking electrical connector rated for NEMA L5-15R configurations, designed for secure, twist-lock connections in demanding electrical applications. This female connector provides a 15-amp, 125-volt interface that resists accidental disconnection under load, making it a standard choice for portable power equipment, generators, and temporary power distribution. Licensed electricians and electrical contractors install this type of connector where a reliable, vibration-resistant connection is required in both residential and light commercial settings.

The 4730 is suited for use with portable generators, power distribution units, and equipment requiring a dependable twist-lock interface. NEMA L5-15R connectors are commonly found in applications where standard straight-blade plugs present an unacceptable disconnect risk, such as on job sites, in entertainment venues, and in mechanical rooms where vibration or cord tension is a factor.
