Series 285 Power Clamp will accept up to 3/0 wire size and can be commoned by a jumper located above the conductor connection area, allowing for maximum conductor size.
Designed for terminating large conductors on control panels and medium-voltage power panels, these DIN rail-mounted terminal blocks offer a current rating of 232A and rated voltage of 1,000V. Spring clamping accepts conductors from 4 AWG to 3/0.
To insert a conductor, simply actuate the cam by making a 3/8 turn using an 8-mm T-wrench. This depresses the spring and opens the conductor insertion area; a locking tab holds the spring in place keeping the wire entrance open. The operator can now use both hands while working to terminate the wire. Once the wire is inserted, the operator makes an additional 1/4 turn with the 8-mm T-wrench, which releases the locking tab and secures the conductor.
Resistivity of the connection is lower than the inherent conductor resistivity, preventing heat buildup. At catastrophic voltage, the conductor fails before the connection.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
