The ERTB terminal blocks designed for all high current draw and aluminum wire applications are for OEM line-voltage power transmission to various electrical equipment. The small footprint, three-pole terminal blocks are said to provide secure, reliable points of connection and transmission for incoming power line service to electrical equipment. The terminal blocks are compact, sturdy, post-to-clamp style unitized blocks that mount to any cabinet or housing attachment point. Each of the electrical poles has a protective strip under each tightening screw that does not pierce either copper-wire strands or softer aluminum wire, holding both equally tight. Each low-profile terminal block has a single row, three-wire pole design to accommodate line voltage on one or two poles, handling neutral and ground wires on the one or two remaining poles.
