700 MCM 4C w/ 750 MCM Ground Twisted XHHW-2 Aluminum Feeder Cable, Priority-Plex®, (Brown, Orange, Yellow, Gray, Green)

This 700 MCM 4-conductor Priority-Plex® assembly with an integrated 750 MCM Ground is a specialized, high-capacity feeder solution for 277/480V 3-phase, 4-wire systems. By factory-twisting the phases (Brown, Orange, Yellow), the neutral (Gray), and a slightly larger 750 MCM Green ground, this cable addresses specific grounding and fault-current requirements in large industrial applications.

Why Choose Priority-Plex® 700 MCM with 750 MCM Ground?

In massive power systems, the ground conductor must be sized to handle potential fault currents without failing. This specific configuration provides an oversized ground (larger than the phase conductors) to ensure maximum safety and system stability. Priority-Plex® technology makes installing these five massive conductors significantly more manageable by twisting them into a single, synchronized unit.

• Heavy-Duty Grounding: The 750 MCM ground provides a superior low-impedance path, often required in facilities with high fault-current potential or specific engineering specifications.

• 480V System Identification: Permanent, factory-colored insulation (Brown, Orange, Yellow, Gray, Green) eliminates the need for manual taping, reducing labor and the risk of wiring errors.

• Reduced Pulling Tension: The pre-twisted configuration prevents "wedging" in large-diameter conduits and lowers friction compared to pulling five individual cables.

• Thermal Performance: XHHW-2 insulation is rated for 90°C and offers exceptional moisture and heat resistance, critical for the high-amperage loads carried by 700 MCM conductors.

• Substation Interconnections: Used as high-capacity feeders between primary switchgear and secondary distribution points.

• Critical Infrastructure: Ideal for hospitals and large data centers where robust grounding and high ampacity are mandatory.

• Utility-Scale Renewables: Main collection lines for large solar or wind farm substations requiring high-capacity grounding.

Technical Note: Installing a 5-conductor 700/750 MCM bundle requires high-capacity pulling equipment and precise planning of conduit fill. Use only AL9CU-rated mechanical or compression connectors and apply an approved antioxidant compound. Ensure all connections are torqued to manufacturer specifications to maintain the integrity of this high-capacity circuit.
