Eaton assembled panelboards are designed for sequence phase connection of branch circuit devices. This allows complete
flexibility of circuit arrangement (1-, 2- or 3-poles) to allow balance of the electrical load on each phase.
Sturdy, rigid chassis assembly assures accurate alignment of interior with panel front; prevents flexing and minimizes
possibility of loosening or damage to current carrying parts during and after installation.
Four point in-and-out adjustment of panel interior is provided to meet critical depth dimensions on flush installations. This
compensates for possible misalignment of box at installation.
Main lugs are mechanical solder-less type and approved for copper or aluminum conductors.
Panelboard Selection Factors
In selecting a panelboard, the following factors must be considered:
Enclosure Box (Can)
- Service (voltage and frequency)
- Interrupting capacity (fully or series rated)
- Ampere rating of main
- Ampere ratings of branches
- Installation environment
Enclosure Fronts (Trim)
- Boxes are code-gauge galvanized steel except for column type panelboards which include a painted box finished in
ANSI-61 light gray to match the trim.
- Standard panelboard cabinets are designed for indoor use. Alternate types are available for indoor and special purpose
- All enclosures are furnished in accordance with Underwriters Laboratories, standards and include wiring gutters with
proper wire bending space. Special cabinets can be provided at an additional charge.
- The box dimensions shown are inside dimensions. For outside dimensions, add 1/4-inch (6.4 mm).
- Standard panelboard boxes are supplied without knockouts (blank endwalls).
- Fronts for all panelboards are made of code-gauge steel and have a high durability ASA-61 light gray finish applied
by a baked-on polyester powder coating paint system.
- The fronts for lighting and appliance branch circuit panelboards and small power distribution panelboards include a door
with rounded corners and concealed hinges that allow a 130- degree door swing. A flush-type latch and lock assembly is
- All locks are keyed alike. These trims are available in both surface and flush mounted designs.
All Eaton panelboards are designed to meet the following applicable industry standards, except where noted:
Canadian Standards Association
Note: Only panelboards containing CSA approved devices can be CSA labeled.
Canadian Electrical Code
Eaton panelboards are seismically tested, seismically qualified, and exceed requirements of the Uniform Building Code
(UBC), California Code Title 24 and BOCA.
