CircleRiver 50 Amp 50ft Generator Cord & SS2-50P Power Inlet Box — 12,500W Weather-Resistant

The CircleRiver 50 Amp 50-foot generator cord paired with a 50 Amp SS2-50P power inlet box gives you a safe, weather-resistant hookup to transfer up to 12,500 watts from a portable generator into your home's transfer switch.

When storms, outages, or construction make grid power unavailable, a properly rated generator cord and inlet box let you connect a portable generator to your home's manual transfer switch quickly and securely. This combo kit includes an ETL-listed 50 ft, 6/3 + 8/1 STW cord with NEMA 14-50P male and NEMA SS2-50R female ends, and a pre-drilled SS2-50P inlet box designed for outdoor installation. The materials and construction focus on durability and safety so the connection remains reliable in harsh conditions.

How does this kit safely connect a generator to my house?

The CircleRiver combo provides the correct plug types and gauge for a 50 Amp, 125/250 V connection to a manual transfer switch. The inlet box keeps the outdoor connection sealed and accessible while the heavy-duty cord maintains proper conductivity and insulation under load.

• Includes NEMA 14-50P to SS2-50R mating connectors for compatible generators and inlet boxes.
• 6/3 + 8/1 AWG pure copper conductors carry up to 12,500 watts at 125/250 V.
• ETL listed components for verified performance and safety.
• Inlet box has removable knockouts for easy conduit or conduit-free installation.

What makes the cord durable for outdoor emergency use?

The cord features heavy-duty, flame-retardant, UV-resistant PVC jacketing and pure copper wiring to resist weather, abrasion, and heat during prolonged use. That construction reduces voltage drop and helps prevent damage from typical outdoor hazards.

• STW-rated jacket resists moisture, sunlight, and cold temperatures.
• Pure copper conductors for improved conductivity and lower heat buildup.
• 50-foot length gives flexible placement between generator and house inlet.
• Rated for 125/250 V and 12,500 W to match common 50 Amp generator setups.

How easy is the inlet box to install and use?

The pre-drilled SS2-50P inlet box arrives ready for mounting on a wall or an exterior electrical enclosure. Its twist-lock inlet reduces accidental disconnection and the removable knockouts streamline routing conduit or cable depending on your installation preferences.

• Pre-drilled mounting holes for quick attachment to siding or a service panel backer.
• Twist-lock SS2-50P inlet secures the connection under load.
• Removable knockouts accommodate different wiring paths or conduit sizes.
• Weather-ready design with gasketed cover when not in use (check local code for enclosure requirements).

When should I choose this 50 Amp combo over smaller options?

Choose the CircleRiver 50 Amp kit if you need to run heavier loads from a portable generator—such as central HVAC, electric ranges, water heaters, or multiple high-draw circuits—through a manual transfer switch. The higher amperage reduces strain on the generator and wiring when compared to smaller extension cords or inlets.

• Ideal for whole-house or large-subpanel emergency powering via manual transfer switch.
• Recommended when generators require a twist-lock 50 Amp inlet for safe connection.
• Better option for longer runs where thicker conductors limit voltage drop.
• Not intended to bypass transfer switches or for permanent utility interconnection without proper equipment.

Who is this for? The CircleRiver 50 Amp 50ft Generator Cord and Power Inlet Box Combo Kit is aimed at homeowners, contractors, and builders who need a ready-to-install, code-conscious solution for connecting a portable generator to a manual transfer switch. If you want a durable, ETL-listed cord set and a pre-drilled inlet box for seasonal storms, construction sites, or backup power plans, this kit delivers the rated capacity and convenient features needed for reliable emergency power connections.
