Arrow Hart 20403 Power-Lock Single Receptacle Grounded 4-Wire Bakelite

The Arrow Hart 20403 is a vintage industrial-grade power-lock single receptacle designed for secure, grounded electrical connections in demanding environments. Featuring a robust Bakelite construction, this 4-wire receptacle ensures reliable performance with locking mechanisms to prevent accidental disconnections, making it ideal for applications in manufacturing, workshops, and heavy-duty equipment setups. Key features include high voltage and current ratings suitable for both AC and DC operations, providing versatility for various power needs. Advantages over similar products include its durable, non-conductive Bakelite body that resists heat and impact, and the power-lock design that enhances safety by securing plugs firmly. However, as a vintage item, it may not comply with modern electrical standards like NEMA configurations, potentially requiring adapters or limiting use in contemporary systems. Benefits include longevity and reliability in legacy installations, while drawbacks involve limited availability of parts and potential incompatibility with current codes. This receptacle is particularly useful for restoring older machinery or in specialized industrial settings where high-amperage, secure connections are essential. Overall, it combines classic engineering with practical functionality, offering a cost-effective solution for specific retrofitting needs.
