Romex SIMpull 10/3 UF-B Building Wire 100 ft - Underground Rated

In this review of the Romex SIMpull 10/3 UF-B building wire, the bottom line is simple: it is a practical choice for anyone needing a durable, direct-burial cable to run feeder lines from an existing distribution point to outdoor loads. The reviewer found the cable best suited for outdoor and underground use where a 600-volt, PVC-sheathed conductor is required. For contractors, electricians, and knowledgeable DIYers who need a reliable feeder for pumps, post lamps, or a small outbuilding, this wire delivers the expected performance and UL listing without unnecessary extras.

Key Features

• Underground rated: Designed for direct burial and underground use, so it can be installed without conduit in many exterior feeder runs.
• 600-volt rating: Provides ample voltage capacity for common residential and light commercial feeder applications.
• 10/3 conductors: Three insulated conductors plus ground allow for 240V or multi-wire branch circuits to supply pumps, sheds, or outdoor lighting.
• PVC jacket: Gray PVC jacket resists moisture and soil conditions typical of buried installations when handled and tamped properly.
• SIMpull construction: Built for easier pulling through non-metallic conduit and tight runs, reducing installer effort on long pulls.

Who It's For

This cable is aimed at electricians, contractors, and competent homeowners who need a long, continuous run of underground-rated feeder wire for outside loads such as post lamps, pumps, or a garden shed supply. Its direct-burial capability and 10/3 configuration make it suitable where a robust, weather-resistant feeder is required.

It is not intended for users who need multi-conductor tray cable, exposed interior wiring types, or specialized high-temperature conductors. If you require a different voltage rating, shielded conductors, or shorter precision lengths delivered on custom reels, you should consider alternative cable types or ordering methods.

Pros & Cons

Pros

• Durable, UL-listed construction for direct burial and outdoor feeder applications.
• 600-volt rating and 10/3 configuration suit common outdoor 240V and multi-wire circuits.
• SIMpull design and PVC jacket make pulling and installation easier in conduit or buried runs.

Cons

• Length concerns have been reported by some customers, so buyers should inspect runs on delivery and plan for a small overage margin.
