Patent number: 7254009Abstract: A company switch-type of electrical switchgear is disclosed having improved safety characteristics and having a reduced profile. The electrical connections are typically all enclosed in one area facing one direction such that access to the connections can be controlled and interlocked with one or more main breakers. By enclosing the connections in one area and directing the leads out of the enclosure in one direction, the size of the enclosure can be reduced while the safety of its use is increased.Type: GrantFiled: October 10, 2006Date of Patent: August 7, 2007Assignee: Lex Products Corp.Inventor: Bruce D. Allen
