Romex romex8/2w/grdmr Nm-b 8/2 Awg Copper Cable

Product Description

The ROMEX romex8/2w/grdmr is an NM-B rated, 8 AWG, 2-conductor copper cable with ground, designed for non-metallic sheathed branch circuit wiring in residential and light commercial applications. The cable features 7-strand copper conductors insulated with PVC and enclosed in a black PVC jacket, rated for 600 volts and 90 degrees C. It carries a 40-amp current rating, making it suitable for heavy-load branch circuits such as electric ranges, dryers, and large HVAC equipment. Licensed electricians install this cable during rough-in and service upgrade work. This listing is sold cut to length, allowing jobsite-specific ordering.

This NM-B cable is used in dry, protected interior locations where non-metallic sheathed cable is permitted by the National Electrical Code. Typical applications include branch circuits feeding high-draw appliances and equipment in residential construction, remodeling, and service panel upgrades. The 8 AWG conductor size is standard for 40-amp dedicated circuits. The cut-to-length format reduces scrap and supports efficient material management on both new construction and retrofit projects.

Key Features

• 8 AWG, 7-strand copper conductors for reliable conductivity and flexibility
• 40-amp current rating supports heavy-load dedicated branch circuits
• 600-volt rated with 90 degrees C temperature rating
• PVC conductor insulation and black PVC outer jacket for durability in protected installations
• NM-B type construction meets NEC requirements for dry interior branch circuit wiring
• Available cut to length to minimize waste on the job

Compatibility

Designed for use in dry, protected interior branch circuit installations where NM-B type non-metallic sheathed cable is permitted under applicable NEC guidelines.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code and all applicable local codes. De-energize the circuit and lock out the panel before making any connections. NM-B cable is approved for dry, protected interior locations only and must not be used in wet, damp, or exposed outdoor environments. Secure and support the cable at intervals required by code and protect it where it passes through framing or other structural members.
