FAQ

What is the maximum wire size this block can accommodate?

The nVent ERIFLEX SB2C400 accepts a wide range of wire sizes. The main input can handle 6 AWG to 350 kcmil (or 16 mm2 to 185 mm2), and the distribution outputs typically handle smaller gauges. Always consult the manufacturer’s datasheet for specific combinations.

Is this distribution block suitable for both copper and aluminum conductors?

Yes, the block is made from tin-plated copper or aluminum, making it compatible with both copper (Cu) and aluminum (Al) conductors. Ensure you use the correct anti-oxidant compound for aluminum connections as per local electrical codes.

What is the recommended tightening torque for the connection screws?

The correct tightening torque is critical for a safe and reliable connection. It varies based on the screw size and conductor used. Refer to the official nVent installation sheet for the SB2C400, which specifies the exact torque values in Newton-meters (Nm) or pound-inches (lb-in).
