65A Power Terminal Strip — One Circuit, Two Wire Entries
The TE Connectivity 1776313-1 is a single-circuit Eurostyle terminal strip from the Buchanan TSB2000 series. It is a power-grade block rated 65A at 600V, accepting wire from 6 AWG down to 14 AWG. The enclosed barrier design keeps live metal covered on the sides, and the chassis-mount closed-bottom body means the screw terminals on top are the only access point for wiring. Two wire entries per circuit allow a feed-through or daisy-chain power run — one wire in, one wire out — which is the standard pattern for distribution blocks in industrial control panels and power supplies.
What the 65A and 600V Ratings Mean for Panel Wiring
The 65A per-circuit current rating is the headline number — this block is sized for main power feeds, not signal or control wiring. At 65A, the screw clamp needs to bear down on the conductor with enough torque to keep contact resistance low; the steel screw with zinc non-hexavalent chromate finish is standard for this duty. The 600V voltage rating covers 480V line-to-line industrial power and 277V line-to-neutral lighting circuits without derating. The PA66 insulation is rated for continuous operation from -35°C to 100°C, which suits most indoor and outdoor cabinet environments, though the -35°C low end is a few degrees warmer than the typical -40°C found on some competing blocks — still adequate for outdoor enclosures in most climates.
Wire Gauge and Termination — 6-14 AWG, Screw Clamp
The 6-14 AWG wire range spans from heavy 6 AWG power cable (rated around 65A in free air) down to 14 AWG control wiring. The Eurostyle screw-clamp termination directly captures the stripped conductor under the screw head — no wire ferrule required, though a ferrule helps with stranded wire in high-vibration environments. The closed bottom means the screw does not pass through the panel; the block mounts to the chassis via its own mounting holes, and the two wire entries per circuit let you land both the incoming feed and the outgoing load on the same block.
Lifecycle and Compliance — Active, ROHS3
No last-time-buy or end-of-life notice is on record, so it can be specified into new panel designs without a sourcing risk.
