For complete stud assembly, order a stud and tube based on thickness of customer’s mounting panel. A short stud must be assembled adjacent to a long stud to maintain clearances required by Underwriters Laboratories(2). Two studs required per pole.

NOTES:
(1) Not UL Iisted.
(2) 400 ampere LA studs of the same length have sufficient clearance; however, customer connections may make it necessary to use a short stud adjacent to a long stud.
(3) 150, 300 and 400 ampere frames only.
(4) This is a special stud that includes six contact nuts for use where bus contact nuts must be used.
(5) For breakers used with terminals and cable connections. Sold in packages of 10.
