Bolt-in circuit breaker with improved terminal fastener retaining structure |
摘要 |
Lateral ears of a terminal strap are bent sharply upward to form sidewalls spaced apart by the width of the strap, openings in the sidewalls overlapping arcuate edge portions of an annular flange of a threaded nut to loosely captivate the nut in position over a hole in the strap for cooperation with a threaded post projecting through the hole upon attachment of the breaker to a panelboard. Upper edges of the sidewall openings are abutted by the flange, and a frustoconical rear surface of the nut is engaged by the thread post upon installation to automatically align the nut and post.
