1 / 7MULMART 50 A Generator Cord and Inlet Box, 25 ft
The MULMART 50 A generator cord and inlet box set pairs a 25-foot cord with NEMA 14-50P and SS2-50R connections for generator power routing. The listing states a 50 A rating and 12,500-watt maximum, but its connection and inlet-box descriptions are inconsistent, so confirm the exact interfaces before purchase.
At a glance
- The cord is described as a NEMA 14-50P male plug to NEMA SS2-50R twist-lock female receptacle, rated 50 A and 125/250 V in the feature text.
- The listing presents the cord and a 50 A generator inlet box as a set, with the inlet box intended for outdoor installation.
- The cord is specified as STW 6/3 + 8/1 AWG. The product description separately identifies three 6 AWG conductors and one 8 AWG ground wire.
- The listing claims ETL listing for the cord and inlet box.

Pros
- A 25-foot cord offers more reach than a short generator lead, subject to the site layout and safe routing.

- Customer feedback describes the cord as sturdy and easy to connect, with reported use alongside high-wattage generators.

What to know before buying
Listing details to confirm
The listing is contradictory and inconsistent about the included connections: it names an SS2-50R cord receptacle and an inlet box, but elsewhere describes the box as NEMA SS2-50P and the cord as SS2-50R/CS6364. Confirm the exact plug, receptacle and inlet-box configuration in the selected listing before buying. The 125/250 V claim in product text also differs from the 250 volts detail field. The ETL listing and waterproof claim are listing claims, not independently confirmed here.
Who is it for?
A good fit for
- Generator owners needing a listed 25-foot, 50 A cord and inlet-box combination, after confirming that the connectors match their generator and installation.
Less suited to
- Buyers who need a clearly confirmed inlet-box connector configuration without checking the listing details first.
- Anyone whose generator, inlet, or required cable reach does not match the stated 50 A NEMA 14-50P to SS2-50R setup.

Customer feedback is largely positive about perceived build quality, performance, durability, value and ease of connection. Some customers report using it with high-wattage equipment, including a 12,000-watt generator. That feedback is useful context for a 50 A, 25-foot cord, but it does not resolve the listing’s inconsistent connector descriptions or establish compatibility with a particular generator.
Positive themes
- Customers describe the cord as sturdy and well made.
- Feedback reports good performance with high-wattage equipment.
- Customers mention straightforward installation and connection.
