Velvac 590263 Power Cable 12 ft 4 ga Copper 4 Way 110 A 200 A

SKU CH-MBBA-47Z3M

Heavy-duty 12 ft, 4-gauge copper power cable with brass contacts and zinc die-cast plugs rated 110 A continuous and 200 A intermittent at 12 V DC

  • Delivers 110 A continuous power for trailer liftgate batteries
  • Handles 200 A intermittent peaks during liftgate operation at 12V DC
  • 12 ft 4-gauge copper wire ensures low resistance over distance
  • Heavy-duty zinc die-cast plugs with spring guards resist wear
  • Meets SAE J-2394 standard for trailer power connections

12 ft 4 ga copper power cable

The Velvac 590263 is a 12 ft 4 ga copper power cable built for trailer liftgate battery connections. It uses a single-pole brass contact inside a green-jacketed assembly with heavy-duty zinc die-cast plugs and spring guards. The cable meets SAE J-2394 and ships in new condition. It is designed for 12V DC liftgate circuits where a reliable high-current feed is required.

Suits liftgate installs needing 110 A continuous

This cable serves installers who need a 4-way plug with an external ground option for liftgate battery wiring at 12V DC. It is not for buyers who require a different wire gauge, a different plug configuration, or a voltage other than 12V DC. It also does not suit applications that demand a multi-pole connector beyond the single-pole design specified.

Verify liftgate voltage.

Confirm the liftgate system operates at 12V DC and that 4 ga wire meets the circuit’s ampacity requirements. Check that the single-pole brass contact and 4-way zinc plug with spring guard match the existing receptacle. Ensure the 144 in length reaches the battery without tension and that the external ground option aligns with the chassis grounding plan.

Questions about this item

What trailer-side connector is required to use the Velvac 590263 power cable?

The cable terminates in a single-pole brass contact that mates with a standard liftgate battery receptacle on the trailer.

Can the 4-gauge copper conductors handle the voltage drop of an older 12 ft liftgate circuit?

At 12 ft the 4 ga copper run is rated for 110 A continuous and 200 A intermittent at 12 V DC, matching SAE J-2394 limits for aged wiring.

How do I verify the external ground option is functioning after installation?

Measure continuity between the green-jacketed cable's ground pin and the trailer chassis; a solid reading confirms the external ground path is complete.
