Aluminum SER cable is a versatile residential/commercial wire used for primary and secondary structures. The “SER” refers to the cable’s primary application as a “service entrance” conductor. SER carries power from a service drop to the electrical meter base, and from that meter base to the distribution panel.
Another application for SER is to use it as a service entrance feeder cable from utility poles to a sub-panel when distributing power to an area outside a building (like a detached garage, pole barn, shop, greenhouse, pool house, etc.). SER is a perfect cable for feeding power to a sub-panel, and, depending on the number of amps a sub-panel can handle, installers will use a variety of sizes of SER as a sub-panel feeder. What’s important to keep in mind when wiring a sub-panel on a structure separate from the home is that the sub-panel will need to be grounded. For this reason, most SER cable comes with the ground included.
The maximum operating temperature for SER should not exceed 90°C in wet or dry locations. The voltage rating is 600 volts. For installation, SER is most suitable as an above-ground service entrance cable. For direct burial aluminum cable for underground distribution, aluminum URD is the preferred solution for most technicians.
SER is made up of compact, stranded AA-8000 series aluminum alloy conductors. With color-coded XHHW-2 insulation on individual conductors. Insulated conductors are cabled with the bare ground wire. A flame retardant fiberglass-reinforced binder tape and sunlight resistant printing on a flame retardant, gray polyvinyl chloride (PVC) material.
Phase conductors are identified by colored stripe configurations on the insulation.
- 3 conductor – Black and Black with Red Stripe
- 4 conductor – Black, Black with White Stripe and Black with Red Stripe
- 5 conductor – Black, Black with White Stripe, Black with Red Stripe and Black with Blue Stripe
