Sersuamr ser1-1-1-3mr Ser 1-1-1-3 Aluminum Round Cable

Product Description

The SERSUAMR ser1-1-1-3mr is an aluminum round service entrance cable in a 1-1-1-3 conductor configuration, sold cut to length. SER cable is a listed service entrance cable type used to deliver power from the utility meter or service panel to load-side distribution equipment. The round construction houses three insulated aluminum phase conductors plus a bare aluminum neutral, all wrapped in a durable outer jacket. This cable type is a standard choice for residential and light commercial electrical service installations and is handled by licensed electricians working to NEC requirements.

SER cable in the 1-1-1-3 size is commonly used for main service feeds and large subpanel installations where aluminum conductors are specified to reduce material cost on higher-ampacity runs. The cut-to-length format allows electricians to order the exact footage needed for a given job, minimizing waste on service upgrades, new construction feeds, and panel replacements.

Key Features

• Aluminum conductors in a 1-1-1-3 configuration: three insulated phase conductors plus a bare neutral
• Round jacket construction for conduit pull-through or direct raceway installations
• SER listing covers service entrance and feeder applications per NEC Article 338
• Cut-to-length format reduces material waste on custom-length service runs
• Aluminum construction offers a lightweight, cost-effective alternative to copper for high-ampacity feeders

Compatibility

Designed as a standard SER-type service entrance cable for use in residential and light commercial electrical service and feeder installations where aluminum 1-1-1-3 conductors are specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 338 and all applicable local electrical codes. De-energize and lock out the service disconnect before making any connections. Use listed aluminum-rated lugs and connectors, and apply appropriate antioxidant compound at termination points per the connector manufacturer instructions. Verify ampacity derating requirements based on conduit fill, ambient temperature, and termination ratings before sizing the overcurrent protection device.
