Heyco Aluminum Neutral Bars are DFARS compliant and rated at 85A for copper wire and 70A for aluminum wire. These bars are designed for ground or power, not for power distribution. The slotted set screws are headless, zinc-plated steel, and will hold smaller wires when the appropriate torque is applied. Due to the tin plating of these neutral bars, they are resistant to oxidation and galvanic corrosion. Heyco Aluminum Neutral Bars offer a size capability of 14AWG to 4AWG for copper wire and 12AWG to 4AWG for aluminum wire.
