12-pole barrier strip for power distribution

This terminal strip provides twelve screw terminals arranged in two rows for connecting conductors in industrial control panels. It accepts wire sizes from 22 AWG up to 10 AWG and is rated for 30 amperes at 600 volts AC. The thermoplastic housing measures 7.71 inches long, 1.34 inches wide and 0.83 inches high.

Replaces loose wire nuts or single-row blocks

The two-row layout doubles connection density in the same panel footprint compared with single-row alternatives. Upgrading is worthwhile when a project needs more circuits without expanding the enclosure or when a barrier strip simplifies maintenance over individual connectors.

Sustained 30 A load with thermoplastic housing

The strip carries its full 30 ampere rating continuously when wired with 10 AWG conductors and proper torque on each screw. Thermoplastic insulation resists heat buildup during extended operation, and the open design allows visual inspection of every connection point.

Questions about this item

What are the overall length, width and height of the terminal strip so I can check panel space?

The strip measures 7.71 in long, 1.34 in wide and 0.83 in high.

How do I wire the screw terminals and what is the most common mistake?

Insert stripped wire into each barrier opening and tighten the screw; the frequent error is leaving strands loose or over-tightening, which damages the 10 AWG maximum conductor.

When should I plan to replace this strip in a 30 A, 600 V AC circuit?

Inspect annually for discoloured housing, cracked thermal-plastic barriers or loose screws; replace immediately if any pole shows heat damage or corrosion.
