Residential Building Wire

DWC features residential buildings specifically designed for use in homes and other residential structures. It is engineered to meet the specific electrical needs of these types of buildings and to ensure safety, reliability, and longevity.

The wire is made of high-quality materials and is designed to meet strict industry standards and codes, ensuring that it is safe for use in residential electrical systems. Residential building wire is typically rated for low voltage (less than 600 volts). These wires are available in various gauges and insulation types to meet your needs.

Our wire for residential buildings is designed to be flexible and easy to install, making it a convenient choice for contractors and DIYers alike. It is also designed to be durable, so that it can withstand the wear and tear of daily use, and it is typically resistant to corrosion, moisture, and other environmental factors.

Benefits of Residential Building Wire:

  1. Affordability – Often more affordable than commercial or industrial building wire, making it a popular choice for residential construction projects. 

  2. Safety – Designed with safety in mind, with features like flame-retardant insulation to reduce the risk of electrical fire. 

  3. Ease of Installation – Simple to install, with lighter and more flexible designs that make it easier to handle and route through electrical systems. 

  4. Energy Efficiency – Helps reduce energy costs and improve the overall energy efficiency of homes.

  5. Compatibility – Compatible with a wide range of electrical devices and systems, making it a versatile choice for residential construction projects.

Whether you’re a homeowner or a contractor, you can trust that DWC residential building wire will help to ensure your electrical systems are compatible with a wide range of electrical devices and appliances, helping to improve the safety, functionality, and efficiency of your home, duplex, townhouse, apartment, or condo. 


Is residential building wire safe to use?

Yes, residential building wire is designed to meet strict safety standards and codes making it safe for use in residential electrical systems. It is typically made of high-quality materials that are resistant to moisture, corrosion, and other environmental factors, and is designed to be flexible and easy to install.

What are the different types of residential building wire?

There are several different types of residential building wire, including Romex, THHN, THWN, and XHHW. The type of wire that is best for a specific project will depend on factors such as the wire's intended use, the amount of current it will be carrying, and the environmental conditions in which it will be used.

Can residential building wire be used outside?

Yes, some types of residential building wire are designed for use outside, while others are intended for indoor use only. If a wire is designed for outdoor use, it will typically be resistant to moisture and other environmental factors.

How is residential building wire installed?

Residential building wire is typically installed by running it through conduit, which is a protective tube that helps to prevent damage to the wire. The wire can be run through the walls, ceilings, and floors of the building, and it can be connected to electrical devices and appliances using electrical boxes, connectors, and other fittings.

What is the difference between residential building wire and industrial wire?

Residential building wire is designed specifically for use in homes and other residential structures, while industrial wire is designed for use in industrial and commercial settings. Industrial wire may be more heavy-duty and able to handle more current than residential building wire, and it may also be more expensive. The type of wire that is used will depend on the specific requirements of the project. 


XLP/USE is similar to XHHW building wire except this product is rated for direct burial applications. This product is also referred to as RHH/RHW meaning it meets the UL standard 854 for service entrance cable. XLP/USE wire is used in service entrance, and branch circuit applications for residential, commercial, industrial and transportation environments for permanent installations utilizing 600 volts or less. The temperature rating for XLP/USE is -40C to 90C in wet or dry environments.

Conductor: Stranded bare copper

Insulation: XLP (Cross-Linked Polyethylene)

Flame Test: IEEE 383 70,000 BTU/hour flame test


XHHW is a general purpose building wire. Approved to use in circuits not exceeding 600 volts. Highly resistant to chemicals, ozone and abrasion. VW-1 rated cables are suitable when the vertical wire flame test is required. This item is sunlight resistant. 1/0 and larger are CT(cable tray) rated.

Conductor: Bare Copper

Insulation: Cross-linked polyethylene (XLP)

Flame Test:  UL and IEEE 383 70,000 BTU/hr flame test. UL VW-1.

Note:  Available in multiple colors


THHN / THWN building wire is used in general purpose wiring for machine tools, appliances and control circuits not exceeding 600 volts. 90C rated in dry locations and 75C in wet locations. Helical wire stripes can be added to this product. VW-1 Rated.1/0 and larger are CT (cable tray) rated.

Conductor: Solid or stranded bare copper

Insulation: PVC

Jacket: Nylon

Notes: Available in various jacket colors

DWC Special Services: Custom wire striping services available for circuit sized THHN

HMWPE – Cathodic Protection

High Molecular Weight Polyethylene (HMWPE) cable is suitable for direct burial in cathodic protection applications for storage tanks, pipelines and other buried or submerged units.  Rated for 600V with a temperature rating of 90C. Sometimes it is called out as cathodic protection.

Conductor: Stranded bare copper

Insulation: High Molecular Weight Polyethylene (HMWPE)

Notes: VW-1 Rated


EPR/HYP is used in commercial and industrial arenas and can be placed in tray when CT rated, direct buried and used in conduit in both wet and dry environments. It is 600 volt rated, VW-1 and 1/0 and larger CT rated. The temperature rating is 90C.

Conductor: Stranded tinned copper

Insulation: EPR

Jacket: Hypalon (CSPE)

Flame Test: IEEE 383 70,000 BTU/hour flame test


AWG (Bare Cu), EPR/USE, Direct Burial, 600V are recommended for use in harsh environments in a broad range of commercial, industrial and utility applications where reliability and maximum performance is required. Approved for installation in conduits, ducts, cable tray when CT rated, direct burial or other approved raceways with maximum conductor temperature of 90°C in wet or dry locations.
