It is an enclosed barrier strip with screw top termination and a closed bottom, designed for chassis or panel mounting. Rated 40 A at 250 V, it accepts wire from 10 AWG down to 22 AWG through two wire entries per circuit, making it a straightforward power distribution point for a single feed-through or splice. The 10-22 AWG wire range covers the common panel-wiring sizes from a 10 AWG main feed down to a 22 AWG control signal. Two wire entries per circuit let you land both the incoming and outgoing conductor under the same screw clamp — useful for daisy-chaining or terminating a single wire with a spare entry. The screw termination uses a steel screw with a zinc, non-hexavalent chromate finish; the closed bottom means the screw does not pass through the block, so the conductor is captured between the screw tip and the bottom of the barrier pocket. No crimp terminal is required — strip the wire, insert, and tighten. ## Current and Voltage — What the Ratings Mean The 40 A rating is the current capacity of the terminal block as a whole, not per-position — since this is a single-circuit strip, that is the full conductor rating. At 250 V, the enclosed barrier provides the creepage and clearance for that voltage class. The base product number is 1776302, and the series is TSB1000 from TE Connectivity's Buchanan line.","metaTitle":"1776302-1 TSB1000 Buchanan Eurostyle Terminal Strip","metaDescription":"1776302-1 TE Connectivity Buchanan TSB1000 Eurostyle terminal strip, 1 circuit, 40 A, 250 V, 10-22 AWG, screw termination, UL94 V-2.
