50 Amp 100 ft Generator Cord and Inlet Box Combo Kit - Emergency Ready

In this review the 50 Amp 100 ft Generator Cord and Power Inlet Box Combo Kit is judged as a straightforward, heavy-duty solution for homeowners and contractors who need a safe way to feed a house from a portable generator. The single biggest reason to buy is its complete, UL and ETL listed pairing: a 100 ft, 50 amp STW cord matched with a pre-drilled, twist-lock SS2-50P inlet box so users get a ready-to-install connection that handles 125/250 V and up to 12,500 watts without hunting for compatible parts.

Key Features

• UL & ETL Listed: The cord and inlet box carry recognized safety listings so users can rely on tested protection when connecting a generator to a transfer switch.
• 100 ft 50 Amp Cord: A long STW 6/3 + 8/1 AWG cable gives generous reach from generator to house, reducing the need to reposition equipment.
• 125/250 V, 12,500 W Capacity: The NEMA 14-50P to SS2-50R twist-lock configuration supports substantial household loads for extended emergency use.
• Pre-drilled Inlet Box: The SS2-50P inlet box arrives with removable knockouts and mounting holes so installation into an exterior wall or panel is straightforward.
• Heavy Duty Construction: Pure copper conductors and flame-retardant, UV resistant PVC jacket protect the cord from weather and abrasion during outdoor use.
• Emergency Ready: Designed for storm and outage scenarios, the kit provides a direct, code-conscious connection to a manual transfer switch or inlet.

Who It's For

This kit suits homeowners who use a portable generator to back up most of a house, small contractors installing a transfer inlet, and anyone who wants a matched cord and inlet box that are already safety listed. The combination saves time compared with sourcing separate components and avoids compatibility guessing when planning an emergency hookup.

It is less appropriate for users who need a permanently hardwired automatic transfer solution or those who require different plug types or shorter custom cable lengths. If you need integrated control panels or breakers included with the inlet, look for a more comprehensive transfer system.

Pros & Cons

Pros

• Clear safety listings (UL for cord, ETL for box) give confidence during emergency use and installation.

Frequently Asked Questions

Will this kit power most household circuits?
Yes; the 50 amp, 125/250 V rating and 12,500 W capacity allow powering many essential circuits when connected through a manual transfer switch, provided the generator can supply the load.

Is the inlet box weather protected?
The pre-drilled SS2-50P inlet box is made to be mounted outdoors and uses knockouts to help seal the installation, but follow local code and use proper sealing and conduit as required.

Can this replace a permanent transfer switch?
No; this kit is intended for manual transfer via an inlet and transfer switch and is not a substitute for a hardwired automatic transfer system.
