Product Overview
This is a ready-made 4/0 AWG red battery cable, 96 inches long, with a 3/8-inch lug on each end and red heat shrink over the lug connections. A lug is the metal ring fitting on the end of the wire that bolts onto a battery or equipment terminal. Heat shrink is a plastic sleeve that shrinks to seal and protect the joint between the lug and the wire.
4/0 AWG (said "four-aught") is a very thick wire. Battery systems use cables this size because battery banks can push large currents at low voltage. The red cable is the usual color for the positive (+) connection. Because the cable comes already built, you don't need a large crimping tool to put the lugs on yourself.
Best For
- Battery bank to inverter connections: Use as the positive (red) lead between a battery bank and an inverter, charger or busbar when your design requires 4/0 AWG wire.
- Battery systems that require 4/0 AWG cables with 3/8-inch lugs: For example, Briggs & Stratton's SimpliPHI 6.6 operator's manual lists red and black 4/0 AWG cables and 3/8-inch closed-end power lugs as required parts that are not included with the battery. Check the lug style and length against your equipment's manual.
- Installers who want a finished cable: A pre-made cable saves crimping and heat-shrinking 4/0 wire in the field.
Key Features & Specifications
| Specification | Details |
|---|---|
| Product type | Pre-assembled DC battery cable |
| Wire size | 4/0 AWG. A larger wire carries more current with less voltage loss. |
| Color | Red jacket with red heat shrink. Red usually marks the positive (+) connection. |
| Length | 96 in (8 ft) |
| Lugs | 3/8 in stud hole on each end. The lug must match the terminal stud size on your battery and equipment. |
| Quantity | One cable |
What You May Also Need
Usually required
- Matching black 4/0 AWG battery cable: A battery connection needs both a positive (red) and a negative (black) cable.
- Battery fuse, breaker or disconnect: Large battery cables need overcurrent protection sized for the wire and the equipment, and a way to switch the battery off for service. Ratings come from electrical code and the battery and inverter manuals.
May be required
- Additional 4/0 AWG cables: Multi-battery banks and longer runs may need more cables or different lengths. The black version of this 96 in cable is listed separately.
- Batteries and a battery inverter: If you are building a new system, choose batteries and an inverter first, then size the cables to their manuals and to electrical code.
Optional upgrades
- Cable management and wiring parts: For routing and supporting heavy cables neatly.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Check the stud size. The lugs fit 3/8-inch studs. They won't fit larger studs, and a loose fit on smaller studs can overheat.
- Check the length. Measure the full cable route before ordering. In many battery systems, the positive and negative cables should be the same length; follow your battery and inverter manuals.
- Size the wire and protection to your system. Wire size and fuse or breaker ratings depend on the current, the cable route and electrical code. 4/0 AWG may be larger than some terminals accept, so check the equipment manuals.
- Ratings not listed. The current rating (ampacity), temperature rating and jacket type are not listed for this assembly. Confirm that 4/0 AWG at this length meets your system's documented requirements.
- Safety. Battery banks can deliver very high currents. Switch off and isolate the battery before connecting cables, and tighten lugs to the equipment manufacturer's torque.
