Encore Wire 188100800030 Nm-b Wire 12 Awg 4 Conductor 250 Ft

Product Description

The ENCORE WIRE 188100800030 is a 4-conductor NM-B building wire rated at 600 volts and 20 amps, designed for permanent indoor electrical installations in residential and light commercial construction. Built with 12 AWG solid copper conductors and a moisture-resistant PVC insulation topped with a nylon/PVC outer jacket, this wire is rated for 90 degrees F continuous operation. The yellow jacket color identifies it as a 20-amp circuit wire per standard electrical conventions. Electricians use this wire for branch circuit wiring in walls, floors, and ceilings where NM-B cable is code-permitted. Each coil contains 250 feet of wire.

This NM-B wire is suited for use in dry or damp locations within residential buildings and light commercial structures where the National Electrical Code permits non-metallic sheathed cable. Typical applications include 20-amp branch circuits feeding kitchen appliances, bathroom circuits, garage circuits, and HVAC equipment outlets. The 4-conductor configuration provides flexibility for switch loops, multi-wire branch circuits, or applications requiring an additional conductor beyond a standard 3-wire run. Licensed electricians pulling wire through framed walls, conduit, or over rafters will find the 250-foot coil practical for most standard circuit runs.

Key Features

• 12 AWG solid copper conductors rated for 20-amp circuits
• 600-volt rating meets standard residential and light commercial branch circuit requirements
• Moisture-resistant PVC insulation with nylon/PVC outer jacket for added durability
• 90 degrees F temperature rating for continuous service
• Yellow jacket for quick 20-amp circuit identification in the field
• 250-foot coil length suitable for most single-circuit runs

Compatibility

Designed as an NEC-compliant NM-B cable for use in residential and permitted light commercial branch circuit wiring applications where non-metallic sheathed cable is an approved wiring method.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit breaker panel before pulling or terminating wire. NM-B cable must be protected from physical damage where exposed and is not approved for installation in conduit, wet locations, or concrete encasement. Verify that the breaker ampacity, outlet ratings, and wire gauge all match before energizing the circuit.
