Construction Details

ABB ReliaGear NEMA 1 enclosures provide the box portion of a compatible panelboard assembly and are designed for indoor electrical installations.

Each enclosure in this product group is 20 inches wide, while the enclosure height varies according to the requirements of the selected ReliaGear panelboard interior.

The enclosure works as part of a complete panelboard system that may also require a compatible interior, front, main device, branch breakers, grounding components, and other accessories depending on the installation.

Available Enclosure Sizes

AB43B 43.5" × 20"

AB49B 49.5" × 20"

AB76B 76.5" × 20"

Catalog Number & Enclosure Size

ABB Catalog Number	Enclosure Height	Width	NEMA Type

AB49B	49.5"	20"	NEMA 1
AB76B	76.5"	20"	NEMA 1

Selecting the Correct Enclosure

43.5" Height

Select AB43B when the compatible ReliaGear panelboard interior requires a 43.5-inch-high, 20-inch-wide NEMA 1 enclosure.

49.5" Height

Select AB49B when the compatible ReliaGear panelboard interior requires a 49.5-inch-high, 20-inch-wide NEMA 1 enclosure.

76.5" Height

Select AB76B when the compatible ReliaGear panelboard interior requires a 76.5-inch-high, 20-inch-wide NEMA 1 enclosure.

NEMA 1 Indoor Protection

NEMA 1 enclosures are intended for indoor use and provide a protective enclosure around compatible electrical equipment.

These enclosures are intended for locations where outdoor weather protection is not required. The installation environment should remain appropriate for the enclosure classification and complete electrical assembly.

For installations requiring protection from rain or outdoor exposure, a compatible enclosure with the appropriate environmental rating should be selected instead.

ReliaGear Pro-Stock Panelboard System

Component-Based Selection

ReliaGear Pro-Stock uses a component-based panelboard system where the appropriate enclosure, interior, front, main device, breakers, and accessories are selected according to project requirements.

Match the Enclosure to the Interior

The selected panelboard interior determines the required box/front height. The enclosure should therefore be matched to the exact compatible interior rather than selected from dimensions alone.

Common Applications

Commercial Electrical Distribution

Commercial buildings
Retail facilities
Office buildings
Electrical rooms
Branch circuit distribution
Building electrical systems

Industrial & Institutional

Industrial facilities
Institutional buildings
Equipment rooms
Indoor utility areas
Replacement panelboard applications

Panelboard Assembly Considerations

The enclosure is one component of the complete ReliaGear panelboard assembly. Additional components are normally required to create a complete panelboard.

Compatible panelboard interior
Compatible panelboard front
Main breaker or main lug configuration as required
Branch circuit breakers
Grounding components where required
Neutral components as applicable
Additional accessories required by the electrical design

Verify all components for compatibility before ordering or assembling the panelboard.

Installation & Selection Considerations

Confirm the exact ReliaGear panelboard interior before selecting the enclosure.
Match the enclosure height to the box/front height required by the selected interior.
Confirm that a 20"-wide enclosure is appropriate for the panelboard configuration.
Verify that a NEMA 1 indoor enclosure is appropriate for the installation environment.
Do not use a NEMA 1 enclosure where a higher environmental protection rating is required.
Verify all required fronts, interiors, breakers, grounding components, and accessories separately.
Maintain applicable electrical working clearances.
Follow manufacturer requirements for conduit and cable entry.
Do not modify the enclosure in a manner that may compromise its intended protection.
De-energize electrical equipment before installation or service.
Installation should be performed by qualified electrical personnel.
Follow current ABB instructions and applicable electrical codes.
