SER Cable: Safe and Code-Compliant Residential and Commercial Wiring

In North American residential and commercial electrical systems, selecting the correct cable is critical for safety, reliability, and compliance with electrical codes.

SER cable (Service Entrance Cable, Round) is a widely used UL-listed building wire designed for service entrance, feeder, and branch circuit applications, delivering long-term performance and code-compliant installations.

What is SER Cable?

SER cable is multi-conductor insulated copper or aluminum wire with a round outer sheath.

It is manufactured to UL 44 (Thermoplastic Insulation) and permitted for residential and commercial service entrance applications per the National Electrical Code (NEC).

SER is ideal for use in conduit, raceway, or direct burial applications (where code allows), and is commonly specified for panel feeders and branch circuits.

Key Structural Features

• Conductors: Copper or aluminum, stranded or solid

• Insulation: THHN/THWN or equivalent thermoplastic, rated for 75°C–90°C

• Outer Sheath: Thermoplastic round jacket

• Voltage Rating: 600 V

• Certification: UL Listed – SER

The round jacket provides mechanical protection while maintaining flexibility for pulling into panels and conduits.

Typical Applications

SER cable is commonly used for:

• Service entrance wiring for homes and small commercial buildings

• Branch circuits and feeders

• Distribution panel and subpanel connections

• Indoor and dry locations (per NEC)

• Residential and light commercial wiring

Its multi-conductor design simplifies installation by reducing the number of individual wires that need to be pulled.

Why Choose SER Cable?

1. UL and NEC Compliance

SER cable meets UL requirements and NEC standards for residential and commercial wiring.

2. Safe and Reliable

The thermoplastic insulation and round jacket protect conductors from heat, moisture, and mechanical damage.

3. Efficient Installation

The multi-conductor design reduces labor time and simplifies service entrance and panel connections.

4. Long-Term Durability

Rated for 600 V, SER cable delivers safe, reliable performance for decades in residential and commercial applications.
