20-pole 2-row terminal strip

This 20-pole, 2-row barrier terminal strip handles up to 30 A at 600 V. It accepts wire from 22 AWG to 10 AWG and uses screw terminals for secure connections. The phenolic housing measures 12.35 in long, 1.36 in wide and 0.81 in high. No cover is included with the unit.

Screw-terminal installation notes

Screw terminals allow straightforward wiring with basic hand tools; strip each conductor to the length recommended for the connector. Over-tightening can crack the phenolic housing, so apply only enough torque to hold the wire firmly. Ensure the centre spacing of 9/16 in matches your layout before mounting the strip.

Suited for power distribution blocks

This strip suits installers building or servicing power distribution blocks that require a 20-pole, 2-row barrier format rated for 30 A. Buyers who need a protective cover, a different pole count, or a higher current rating should look at alternative terminal strips. The black phenolic housing is fixed and cannot be changed.
