A Reliance Controls Power Inlet Box, often referred to as a "Termination Unit" in this context, is an essential electrical component designed to safely and conveniently connect a portable generator to a home or building's electrical system. It provides a dedicated, weatherproof, and secured external input point for generator power. This allows for the safe backfeeding of selected circuits via a transfer switch or a generator-ready load center, preventing dangerous backfeeding onto the utility grid.

Design: Typically installed on the exterior of a building, it features a heavy-duty, NEMA-rated enclosure to withstand outdoor elements.
Connection: Contains a specific generator inlet receptacle (e.g., NEMA L14-30 for 30A, 125/250V) designed to accept the generator's power cord.
Wiring: Internally, it provides terminal blocks for direct wiring to the main electrical panel via a transfer switch. Many models come with pre-wired grounding.
Cover: Features a spring-loaded, self-closing cover to protect the receptacle from moisture, debris, and insects when not in use.
Knockouts: Multiple conduit knockouts are provided for flexible wiring installation.

Product Parameters

Amperage Rating: Common ratings include 30A, 50A, and sometimes higher, matching common portable generator outputs.
Voltage Rating: Typically 125/250V AC, suitable for household split-phase power.
Receptacle Type: NEMA L14-30 (for 30A), NEMA L14-50 (for 50A), or other specific NEMA configurations.
Enclosure Rating: NEMA 3R for outdoor use, providing protection against rain, sleet, snow, and external ice formation.
Material: Usually robust metallic construction (e.g., powder-coated steel) or durable non-metallic composites.
Dimensions: Vary by model and amperage rating, but are designed to be compact for exterior mounting.
Certifications: cULus Listed, ensuring compliance with North American safety standards.

Product Advantages

Safety: Prevents dangerous backfeeding of generator power into the utility grid, protecting utility workers and the electrical system.
Convenience: Provides a quick and easy connection point for a portable generator, eliminating the need for temporary wiring or running extension cords through windows.
Weatherproof: NEMA 3R rated enclosure protects internal components from harsh weather conditions.
Durability: Built with robust materials to withstand outdoor exposure and repeated use.
Ease of Installation: Often features ample wiring space, pre-wired grounding, and removable faces for quicker and simpler installation by qualified electricians.
Versatility: Compatible with various transfer switches, manual transfer panels, and generator-ready load centers.

Important Considerations

Professional Installation: Installation should always be performed by a qualified electrician to ensure compliance with local electrical codes and safety standards.
Transfer Switch: A power inlet box must be used in conjunction with a properly installed transfer switch (manual or automatic) to isolate the house wiring from the utility grid.
Amperage Matching: Ensure the power inlet box's amperage rating matches or exceeds the generator's output and is appropriately sized for the circuits being powered.
Location: Install in a location that is easily accessible for generator connection, away from windows and doors, and in compliance with local fire codes for generator exhaust.
Cord Length: Consider the necessary length of the generator power cord to reach the inlet box from the generator's preferred operating location.

Product Applications

Residential Backup Power: The most common application, providing a safe and convenient way to power essential circuits in a home during utility outages.
Small Commercial Buildings: Used in small businesses, offices, or workshops to provide temporary power for critical operations.
Emergency Services: For fire stations, police departments, or other emergency facilities requiring backup power for essential equipment.
Job Sites/Construction: Providing temporary power to tools and equipment on construction sites where utility power is not yet available or reliable.
Event Power: For outdoor events, festivals, or temporary setups requiring generator power.
