ROMEX

ROMEX is a brand of electrical cables manufactured by Southwire Company, LLC, a North American wire and cable producer headquartered in Carrollton, Georgia. The ROMEX brand is primarily associated with non-metallic sheathed cable (NM-B) and underground feeder cable (UF-B) used in residential and commercial electrical installations. The product line available through 3G Electric focuses on UF-B underground feeder cables, which are designed for direct burial in the ground or for use in wet, corrosive environments where moisture resistance is required. These cables are constructed with a gray, sunlight-resistant PVC jacket that provides protection against moisture, fungus, and corrosion. The conductors are copper, with a bare copper grounding conductor included in each cable assembly. The UF-B cables supplied by 3G Electric are listed to UL 493 (Standard for Safety for Underground Feeder and Branch-Circuit Cable) and UL 83 (Standard for Safety for Thermoplastic-Insulated Wires and Cables), ensuring compliance with recognized safety and performance standards. Available conductor sizes range from 14 AWG to 8 AWG, with configurations of 2 or 3 insulated conductors (black, white, and red for 3-conductor cables) plus a bare grounding conductor. Cable lengths are offered in 25 ft and 250 ft spools, accommodating both small repair jobs and larger installation projects. The cables are rated for 600 volts and are suitable for use in branch circuits, feeder circuits, and service-entrance applications when installed per the National Electrical Code (NEC) requirements for direct burial or in wet locations. 3G Electric stocks multiple SKUs of ROMEX UF-B cables, providing procurement specialists and plant engineers with a reliable source for these critical wiring components. The cables are packaged on spools for easy handling and dispensing on job sites. As a distributor, 3G Electric supports global logistics, enabling engineers and maintenance managers worldwide to source these cables for projects involving outdoor lighting, landscape power, pump stations, and other underground electrical infrastructure. The ROMEX brand is widely recognized in the electrical industry for its consistent quality and adherence to UL standards, making it a practical choice for applications where code compliance and long-term durability are required.

Frequently asked questions

Common questions about ROMEX from 3G Electric.

What is the difference between ROMEX NM-B and UF-B cable?

ROMEX NM-B (non-metallic sheathed cable) is intended for dry, indoor locations only, while UF-B (underground feeder) cable is rated for direct burial in the ground and for use in wet or damp environments. UF-B has a solid, moisture-resistant PVC jacket that is sunlight-resistant, whereas NM-B has a thinner, less durable jacket. UF-B is also suitable for use in concrete or masonry, making it the appropriate choice for outdoor and underground installations.

What UL standards do ROMEX UF-B cables comply with?

ROMEX UF-B cables supplied by 3G Electric are listed to UL 493 (Standard for Safety for Underground Feeder and Branch-Circuit Cable) and UL 83 (Standard for Safety for Thermoplastic-Insulated Wires and Cables). UL 493 covers the construction and performance requirements for cables intended for direct burial and wet locations. UL 83 applies to the thermoplastic insulation on the individual conductors. These listings indicate the cables have been tested for safety and performance.

What conductor sizes and configurations are available for ROMEX UF-B cables from 3G Electric?

3G Electric stocks ROMEX UF-B cables in conductor sizes 14 AWG, 12 AWG, 10 AWG, and 8 AWG. Configurations include 2-conductor cables (black and white insulated conductors plus a bare grounding conductor) and 3-conductor cables (black, white, and red insulated conductors plus a bare grounding conductor). Cable lengths are available in 25 ft and 250 ft spools.

Can ROMEX UF-B cable be used for direct burial without conduit?

Yes, ROMEX UF-B cable is specifically designed for direct burial in the ground without the need for conduit, provided it is installed at the depth required by the National Electrical Code (NEC) for the application. The cable's gray PVC jacket is moisture-resistant and sunlight-resistant, allowing it to withstand soil conditions and exposure. However, local codes may have additional requirements, so always verify with the authority having jurisdiction.

What is the voltage rating of ROMEX UF-B cables?

ROMEX UF-B cables are rated for 600 volts. This makes them suitable for use in branch circuits, feeder circuits, and service-entrance applications in residential and commercial electrical systems. The 600-volt rating is standard for most low-voltage power distribution applications in buildings and outdoor installations.

Does 3G Electric ship ROMEX UF-B cables internationally?

Yes, 3G Electric ships ROMEX UF-B cables globally. As a distributor based in Singapore with a worldwide logistics network, 3G Electric can arrange shipping to various countries. Procurement specialists and engineers can request a quote for specific SKUs and quantities, and the company will provide shipping options and lead times based on the destination.
