50 Amp Generator Inlet Box NEMA 3R SS2-50P ETL Listed & Weatherproof

Why Choose this Inlet Box?

When the grid goes down — whether from a tornado, blizzard, or localized outage — the Kohree 50 Amp Generator Power Inlet Box is the critical link that connects your portable generator to your home's transfer switch or electrical panel. Every design decision in this unit serves one goal: safe, reliable, weather-resistant power delivery when you need it most.

• ETL-Certified Safety: Backed by ETL listing, the PB50 inlet box carries a 125/250V rating and a robust 12,500W capacity. It's engineered to pair flawlessly with all 50A 3-prong NEMA SS2-50P generators and compatible cords, giving you a continuous, code-compliant power bridge between your generator and home.

  

• Tool-Free Wiring Access: Say goodbye to cumbersome knockouts and time-consuming drilling. Four precision-pre-drilled 1.2" openings — located on the left, right, bottom, and back — each protected by easily removable covers. Route wiring to your transfer switch or electrical panel without damaging the unit.

  

• Integrated Green Power Indicator: A vibrant green indicator light is embedded within the flip cover, so you can verify a secure power connection at a glance — even in low-light conditions. A simple "Green-On" signals a successful link, enhancing safety during nighttime installations or in dimly lit areas.

  

• Spacious 3.1" Interior: The thoughtfully designed 3.1" spacious interior and detachable front panel facilitate straightforward wire placement and accelerate the wiring process. Enhanced airflow promotes rapid heat dissipation, prolonging the product's lifespan and maintaining peak performance during extended generator runs.

  

• Built to Endure the Elements: Crafted from heavy-duty steel and fortified with a comprehensive corrosion-resistant coating — both internally and externally — this inlet box stands as a fortress against nature's onslaughts. The front lid seals tightly when idle, safeguarding the connector from invasive dust and moisture for lasting weatherproof reliability.

Is This the Right Inlet Box for Your Setup?

💡 Advice: This 50A inlet box is the industry-standard choice for most portable generator-to-home setups. If your generator has a 3-prong NEMA SS2-50P receptacle and outputs up to 12,500W, this box is your match. For smaller 30A generators, consider 30A inlet box (NEMA L14-30P) instead.
