The Champion 50A 125/250V Power Inlet Box provides a weatherproof, code-ready inlet to route generator power into your home safely and easily.

When you need a dependable exterior connection for a portable generator, this Champion inlet box gives you a dedicated, recessed 50A 125/250V SS2-50P entry point that mates with standard generator cords. Built for outdoor use with a NEMA 3R-rated enclosure and ¾" knockouts, it simplifies wiring while protecting the inlet from weather and debris.

How does this inlet box make connecting a generator safer and simpler?

The recessed SS2-50P inlet plug reduces exposure to the elements and accidental contact, and the pre-wired ground connection helps meet basic code wiring requirements. The NEMA 3R enclosure resists rain and snow, and the LED indicator gives an immediate visual cue that generator power is present.

• Recessed inlet plug reduces wear and risk of moisture intrusion
• Pre-wired ground simplifies connections for electricians
• NEMA 3R enclosure protects outdoor installations from weather
• Visible LED on cover confirms generator feed without opening the box

What do I need to install the inlet box on my home?

Installation requires cutting an exterior opening and routing wiring into your service transfer equipment or breaker panel per local code. The unit includes ¾" knockouts to accept conduit and wiring, and the recessed design aligns with standard inlets and 50A generator cords.

• Mounting location on exterior wall close to transfer equipment or inlet conduit run
• Conduit or cable sized to local electrical code and breaker configuration
• Compatible 50A 125/250V generator power cord (Champion model #100828 recommended)
• Professional electrician recommended unless you are qualified to work on service wiring

Will this work with my portable generator and existing cords?

The inlet uses a standard SS2-50P 50A 125/250V configuration that matches most portable generator outlet cords rated for 50A service. Pair it with a proper 50A cord and ensure your generator’s breaker and your home transfer method are compatible with a 50A inlet.
