Construction Details
These ReliaGear Pro-Stock interiors are designed with copper bus construction for compatible 480/277V panelboard applications.
The interior is the electrical distribution portion of the panelboard assembly and is selected according to circuit count, ampere rating, enclosure height, and associated ReliaGear components.
Each model in this product group includes the specified number of TGL2 ground bars. The required enclosure, front, main device, branch breakers, and other accessories are selected separately as applicable to the complete panelboard assembly.

Selecting the Correct Interior
30 Circuit / 100-225A
Select AEU3302RCXAXT1B4 for a 30-circuit configuration with a 100-225A rating and 43.5" enclosure-height requirement.
42 Circuit / 100-225A
Select AEU3422RCXAXT1B4 for a 42-circuit configuration with a 100-225A rating and 49.5" enclosure-height requirement.
42 Circuit / 400A
Select AEU3424RCXAXT1B4 for a 42-circuit configuration with a 400A rating and 76.5" enclosure-height requirement.
Copper Bus Construction
This AEU product family uses copper bus construction as identified in the product configuration.
Bus material is an important part of panelboard selection and should be matched to the electrical design, project specification, ampere rating, and required ReliaGear assembly.
Confirm all related panelboard components are compatible with the selected copper-bus interior before ordering.
480/277V Panelboard Configuration
480V Distribution
These interiors are intended for compatible 480/277V panelboard configurations and should be selected only when the electrical system design matches the required voltage.
277V Line-to-Neutral Loads
The 480/277V system configuration supports compatible three-phase distribution applications where 277V line-to-neutral loads are part of the electrical design.
Ground Bar Configuration
3 TGL2 Ground Bars
Catalog number AEU3302RCXAXT1B4 is configured with three TGL2 ground bars.
4 TGL2 Ground Bars
Catalog numbers AEU3422RCXAXT1B4 and AEU3424RCXAXT1B4 are configured with four TGL2 ground bars.
ReliaGear Pro-Stock Panelboard System
Component-Based Assembly
ReliaGear Pro-Stock uses a component-based panelboard system where the interior, enclosure, front, main device, breakers, and accessories are selected according to the electrical installation.
Interior Determines Enclosure Height
The selected interior determines the required enclosure and front height. Match the 43.5", 49.5", or 76.5" interior requirement to a compatible ReliaGear enclosure and front.
