Description
NSI Industries AL-P1-K6 Connector-Bloks Power Distribution Block 310A 600V
The NSI Industries AL-P1-K6 is a single-pole modular power distribution block from the Connector-Bloks series, rated at 310 amps per pole and 600V max. It accepts a large-gauge line-side feeder (up to 350 MCM) and distributes power to multiple smaller load-side circuits (2/0–14 AWG), making it a practical solution for splitting a single incoming feeder into multiple branch circuit connections within a panelboard, switchboard, or motor control center enclosure.

Applications
Modular power distribution blocks like the AL-P1-K6 are standard components in industrial and commercial electrical panels, used to tap a single large-gauge feeder and distribute it to multiple smaller branch conductors without requiring additional breakers or splices. They are commonly installed in panelboards, switchboards, motor control centers (MCCs), and custom-built electrical enclosures where a feeder must be split at the point of distribution. The CU9AL rating makes the block compatible with both copper and aluminum wiring — an important consideration in commercial and industrial installations where aluminum feeders are common. The 350 MCM line-side capacity and 310A per-pole rating suit it for high-current service entrance and sub-panel distribution applications. NSI Industries' Connector-Bloks line is widely used by electricians and panel builders in the United States and is a well-established product family in the industrial electrical supply trade.
This NSI Industries AL-P1-K6 Connector-Bloks modular power distribution block has been inspected and is in good used condition. It was pulled from a working electrical installation. The black thermoplastic housing shows normal surface wear and minor scuffing consistent with field use. The aluminum terminal lugs and load-side set-screw ports are intact with no visible damage. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
