Fusion 4002U 2 ga. Straight Terminal

The Fusion 4002U is a straight-alignment battery terminal built for 2-gauge wire in automotive and industrial electrical systems. Its green colour code and stamped polarity markings help installers identify the correct connection quickly. The clamp is tin-plated copper for conductivity and corrosion resistance. It meets UL, CUL and RoHS standards and includes the necessary fasteners for a secure fit.

Sustained Load Behaviour

Tin-plated copper maintains low contact resistance over long service periods, reducing voltage drop when the circuit carries continuous current. The permanent crimp connection resists loosening from vibration better than temporary clamp designs. Stamped gauge and polarity markings remain legible after extended exposure to heat and battery vapour, preventing misidentification during later maintenance.

Installation Notes

Crimping 2-gauge wire requires a proper heavy-duty crimp tool; insufficient compression creates a high-resistance joint that can overheat. The straight alignment and top-mount stud limit routing flexibility in tight battery trays. The 5/16-inch stud size must match the existing battery post or bus bar, otherwise an adapter or different terminal is needed.

Questions about this item

How much heat does the copper-and-tin terminal generate when carrying heavy current all day?

The tin-plated copper construction keeps resistance low, so the clamp runs cool even under continuous high-amperage loads.

What cable size and crimp tool do I need to install this 2 ga. terminal?

Use 2-gauge wire and a matching crimp die; the 5/16 in. stud and included fasteners complete the connection.

Will the straight clamp fit the existing top-post battery and bus-bar spacing on my older vehicle?

The 2 3/8 in. overall length and 1 in. width match standard top-post dimensions, so it aligns with legacy hardware.
