B-LINE XBUTT4RD – Frequently Asked Questions

1) What wire range does the B-Line XBUTT4RD terminal block accept?
The XBUTT4RD double level block takes conductors from #26 to #10 AWG, with the maximum being 10 AWG (4 mm2). If your feeder is larger than 10 AWG, this is the wrong block for that landing.
2) What current can the XBUTT4RD block carry?
Amperage is 30A under UL and 36A under IEC. Size your branch protection to the UL 30A figure when the block sits in a UL-rated enclosure.
3) Does the XBUTT4RD use screw clamps or a spring cage connection?
Screw connection. Each level is clamped with a screw, which means you can re-torque the landing at commissioning and after the first heat cycle, and the block accepts both solid and stranded conductors within the #26 to #10 AWG range.
4) Why is the XBUTT4RD red, and can I mix it with other colors in the same rail run?
Red is the body color on the XBUTT4RD, commonly used to segregate a circuit type or voltage group on the rail. It's the same IEC-XB Series screw connection double level block regardless of color, so mixing colors in one run is purely a marking choice and doesn't change the electrical ratings.
