Patent number: 10840689Abstract: A tap-off box includes a latch that automatically secures the tap-off box to a busway upon insertion of a mast into the busway. The latch is in the form of a single spring-loaded member that latches onto a rail as the masthead is pushed into the busway. A push button actuated camming member pushes the latch away from the rail to enable the masthead to be withdrawn from the busway. The push button and camming member are independent of the mechanism that extends and retracts the contacts while the masthead is inserted and latched into the busway. The tap-off box may also include non-contact current monitoring sensors with voltage sensing inserts that an auxiliary breaker switch in applications other than a tap-off box, and an infrared emitting faceplate that can be adapted for monitoring a variety of breakers from outside the tap-off box.Type: GrantFiled: October 9, 2018Date of Patent: November 17, 2020Assignee: POWER DISTRIBUTION, INC.Inventors: Mario L.

Patent number: 9979166Abstract: In order to reduce service procedure time and labor costs, while increasing overall uptime, the electrical equipment cabinet of the invention includes a main service door that is integrated with the dead front. The dead front panel is fixed to and movable with the main service door, and therefore access to high voltage equipment situated behind the dead front is achieved by simply opening the main service door, without the need to first unlock and open the main service door and then unlock, open, and/or remove the dead front panel. Controls on the front side of the dead front are easily and safely accessible, when the main service door is closed, through a dead front control access door positioned within an opening of the main service door.Type: GrantFiled: April 21, 2017Date of Patent: May 22, 2018Assignee: POWER DISTRIBUTION, INC.Inventors: Richard Shimabukuro, Long Justin Nguyen, Isaac Folk, Christopher Morgan Davis, Mingbo Zhao

Patent number: 9197953Abstract: An adjustable mounting assembly has first and second mounting portions. The first mounting portion has an engagement arm with an adjustable end having first engagement teeth disposed about a first axis of rotation. The end portion has an adjustable second portion rotatable about the first axis of rotation, and having second engagement teeth that intermesh with the first engagement teeth to retain the second portion in an adjustable pan-position. The second portion has third engagement teeth disposed about a second axis of rotation angularly offset from the first axis of rotation. A second mounting portion is adjustably attached at an attachment portion to the first mounting portion, and the attachment portion has fourth engagement teeth disposed about the second axis of rotation that intermesh with the third engagement teeth to retain the second mounting portion is a selected tilt position.Type: GrantFiled: March 30, 2015Date of Patent: November 24, 2015Assignee: QSC Audio Products, LLCInventors: Dave Neil Simpson, Bernard Francis Hawkins, Yasushi Richard Shimabukuro, Jason Delarm, Douglas William Teulie, Alex Aranda
