Eaton Tripp Lite Series Power Extension Cord | NEMA L5-30P to NEMA L5-20R with Breaker — 20A, 120V, 10 AWG, 2 ft (0.61 m), Black

The Eaton Tripp Lite Series Power Extension Cord is a premium electrical accessory engineered for dependable power delivery in demanding environments. Designed to pair a NEMA L5-30P locking plug with a NEMA L5-20R locking receptacle and built-in breaker protection, this cord is ideal for safeguarding generators, transfer switches, and high-load equipment. Whether you’re powering essential devices on a busy job site or expanding your power distribution at a backup power station, this extension cord provides a secure, reliable connection with robust construction that stands up to repeated use.

• Locking, twist-lock connectors for secure connections. The NEMA L5-30P locking plug and the NEMA L5-20R locking receptacle are designed to resist accidental disconnection, even in cramped spaces or during movement. This makes it an excellent choice for generator hookups, temporary power distribution, and professional applications where vibration or movement can loosen standard straight-blade cords. The locking configuration ensures a tight, vibration-resistant fit that helps maintain continuous power flow to critical equipment.
• Integrated breaker for added protection. Featuring a built-in circuit breaker, this extension cord helps prevent overloads from damaging connected devices and circuits. The breaker provides a reliable safeguard against surge and fault conditions common on job sites or during generator start-up, reducing wear on equipment and lowering the risk of nuisance trips. When the load is too high, the breaker trips to interrupt power, and a quick reset restores safe operation once conditions are corrected.
• Heavy-duty 10 AWG copper conductors for durable performance. The core wires are 10 AWG copper, delivering low resistance and strong current capability for 20A at 120V. This larger gauge minimizes voltage drop over the short run and supports reliable operation of demanding equipment. Paired with a rugged jacket, the cord maintains flexibility and resilience under typical workplace conditions, helping you power essential gear with confidence.
• Compact 2-foot length for flexible placement and neat setups. At 2 ft (0.61 m), this extension cord provides the right balance of reach and manageability on crowded workbenches, generator stations, or behind rack-mounted equipment. The short length reduces cable clutter while still offering enough reach to connect between power sources and devices without creating excessive slack that can become a tripping hazard.
• Durable, professional-grade construction with safe handling features. The black jacket is designed for durability and a professional appearance, while molded connectors with reinforced strain relief help withstand repeated plugging and unplugging. This design reduces wear on both the plug and receptacle interfaces, prolonging service life and maintaining consistent electrical contact over time. The overall build emphasizes reliability in harsh environments, including workshops, service desks, and portable power setups.

how to install Eaton Tripp Lite Series Power Extension Cord

Installing this extension cord is straightforward and safe when performed with the power off. Begin by ensuring the available power source or generator is de-energized. Align the NEMA L5-30P locking plug with the corresponding locking receptacle on the power source, and rotate or twist to lock securely into place. Do the same on the device end by connecting the NEMA L5-20R locking receptacle to the equipment or transfer switch you intend to power. Avoid forcing connectors or bending the cord at sharp angles; route the cable in a clear path away from heat sources, moisture, or sharp edges that could damage the insulation. Once connected, reset the power source and carefully test the circuit. If the built-in breaker trips, reduce the load or unplug some devices, then reset the breaker to resume operation. Do not modify connectors or use the cord with incompatible outlets. Regularly inspect the cord for signs of wear, including cracks in insulation, loose connectors, or frayed conductors, and replace if any damage is detected. This cord is designed to deliver reliable performance in professional environments where secure, high-quality connections are essential for safety and efficiency.

Frequently asked questions

• What devices can I power with this extension cord? It is designed for high-demand equipment and systems that require locking NEMA connections, such as generators, transfer switches, and power distribution setups that use L5-30P and L5-20R interfaces. It is ideal for temporary power distribution in professional settings.
• What does the built-in breaker do? The integrated breaker provides overcurrent protection, helping to prevent damage to connected equipment and electrical circuits. If the load exceeds the rated capacity, the breaker trips to interrupt power. After removing excess load, the breaker can be reset to restore supply.
• What is the length and gauge of the cord? The cord is 2 ft (0.61 m) long and uses 10 AWG copper conductors, which support a 20A, 120V rating with reliable current delivery and reduced voltage drop over the short run.
• Can this cord be used in outdoor environments? The product description indicates robust construction suitable for challenging settings, but always verify outdoor suitability with the manufacturer’s guidelines and product packaging, as environmental exposure can affect insulation and safety requirements.
• Is this cord compatible with all NEMA L5 connections? It is specifically designed for NEMA L5-30P locking plugs and NEMA L5-20R locking receptacles. Use with other NEMA configurations is not recommended, as mismatched connectors can lead to poor connections or electrical hazards.
