US Patent:

44727615, Sep 18, 1984

Filed:

Jun 18, 1982

Appl. No.:

6/389996

Inventors:

Howard E. Koslosky - Milwaukee WI
George Greger - Waukesha WI

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H02B 104

US Classification:

361355

Abstract:

A panelboard (2) is divided into segments for three-pole industrial frame circuit breakers (30,46). Bus bars (A,B,C) in each segment have two sets of mountng holes (18,20,22; 20,24,26,28) for replaceably receiving branch circuit connectors (34,36,38; 42,44; 58,60) for either industrial or residential frame circuit breakers, thereby enabling residential frame circuit breakers (52,54) to be installed at any segment. A dead front cover (68) having a single opening (72) encompassing all segments, and kits comprising branch circuit connectors, insulating barriers (62) and filler plates (76,78,80,84,86,88) provide complete flexibility to the circuit breaker arrangement. An auxiliary main circuit breaker (96) kit enables the panelboard to be readily converted from a lug main to a breaker main panelboard.

International Classification:

H02B 104

US Classification:

361363

Abstract:

Plug-on enclosed fusible switches, enclosed lug devices and non-enclosed molded case circuit breakers are attached to a panelboard in a single or side-by-side double row. Spring biased latches retain the devices to the panelboard. Locating notches on the panelboard locate the devices at incremental spacing to provide a variable, compact arrangement for the devices. Filler plates and end structures on the devices cooperate with a cover for the panelboard to provide an integral dead front. The panelboard is particularly adapted for field assmebly, including attachment of a main feed device which effects a plug-on feed in either a single or electrically parallel double panel arrangement.
