The 15 A per circuit rating at 300 V means each position can carry a moderate load for control panel power distribution, lighting circuits, or industrial sensor supplies. ## Wire Termination and Gauge Range Each circuit terminates with a screw with captive plate — the plate stays captured in the screw thread, so it does not drop out during field wiring. The block accepts 16-22 AWG wire. ## Side Stacking for Multi-Circuit Assemblies The block includes a side stacking (interlocking) feature, so multiple 2-circuit blocks can be ganged together side-by-side to create a larger terminal strip without a separate end barrier.","metaTitle":"1977477-2 Barrier Block, 2 Circuits, 0.325\" Pitch, 15 A","metaDescription":"TE Connectivity 1977477-2 barrier strip, 2 circuits, 0.325\" pitch, 15 A, 300 V, 16-22 AWG, UL94 V-0.
