islewire 50A Generator Power Inlet Box SS2-50P, Galvanized Steel Weatherproof NEMA 3R with LED Indicator

The islewire 50 Amp Generator Power Inlet Box is an outdoor-rated SS2-50P twist-lock inlet that delivers up to 12,500W of emergency power through a weatherproof, ETL-listed enclosure with an integrated LED status indicator.

This inlet box provides a safe, code-friendly connection point for portable generators, RVs, and standby power systems. Built from galvanized steel with a NEMA 3R rainproof rating, it keeps electrical connections protected from rain, snow, and UV exposure while offering easy wiring access through multiple pre-drilled knockouts. The unit is compatible with standard 4-prong 50 Amp generator cords and accepts 4–6 AWG conductors for heavy-duty installations.

How does this inlet box make generator hookups safer and simpler?

The islewire inlet encloses the twist-lock plug and wiring inside a lockable cover to prevent accidental contact and to keep moisture out. A built-in green LED indicates when power is present, reducing guesswork and helping avoid backfeeding mistakes. Installers benefit from pre-drilled knockouts and a removable front cover that speed up routing and termination.

• Lockable, weatherproof cover for protected connections
• Green LED power indicator to show live feed status
• Multiple pre-drilled knockouts for left/right/bottom/back wiring
• Compatible with SS2-50P 4-prong 50 Amp generator cords

What are the electrical specs and compatibility details?

This inlet is rated 125/250V and supports up to 12,500 watts at 50 amps, suitable for most portable generators and transfer switch inputs. It accepts heavy-gauge conductors (4–6 AWG) commonly used in generator installations. The SS2-50P four-prong twist-lock pattern is a standard connector type used across North America.

• Voltage: 125/250V — suitable for split-phase generator outputs
• Current: 50 Amp continuous rating, 12,500W maximum
• Wire gauge: 4–6 AWG compatibility for durable connections
• Connector: NEMA SS2-50P standard 4-prong twist-lock

Will this box endure outdoor conditions and code requirements?

The enclosure is constructed from high-grade galvanized steel and carries a NEMA 3R rainproof rating, offering resistance to rust, corrosion, and UV damage. It is ETL listed for safety, which helps meet inspection and code obligations for outdoor electrical equipment. The design is intended to withstand typical weather exposure while protecting critical generator feed points.

• Galvanized steel housing resists corrosion and UV deterioration
• NEMA 3R rainproof classification for outdoor mounting
• ETL listing confirms compliance with recognized safety standards
• Durable cover and gasket help exclude water and debris

How easy is it to install and maintain this inlet box?

Installation is straightforward for electricians and knowledgeable DIYers: the box includes pre-drilled knockouts on multiple sides and a removable front cover for quick access to terminals. The LED indicator reduces troubleshooting time by showing when the generator feed is active. Routine maintenance is limited to visual inspections and keeping the cover and gasket clean for a reliable seal.

• Pre-drilled knockouts simplify conduit and cable entry points
