Construction Details
These ABB ReliaHome load centers use a main-lug-only configuration with plug-on neutral branch breaker construction for compatible residential electrical distribution applications.
The PAL product family uses aluminum bus construction and is designed for single-phase, 3-wire, 120/240V AC service.
Each model in this product group is supplied as an indoor NEMA 1 combination enclosure with a door. The catalog configurations listed here do not include a factory-installed 200A main breaker.
ABB lists the interrupting capacity for these PAL models at 22 kAIC. The complete installation, branch breakers, grounding, conductor sizes, and upstream overcurrent protection should be selected according to the electrical system and applicable requirements.

Plug-On Neutral Design
Plug-On Neutral Breaker Style
All six PAL catalog numbers in this product group are identified by ABB as using a plug-on neutral circuit breaker style.
Residential Breaker Compatibility
ABB identifies the ReliaHome load center family as designed to work with its compatible residential circuit breaker platform. Breaker type and compatibility should be confirmed for the exact installation.
Main Lug Only Configuration
These PAL load centers are configured as Main Lug Only (MLO) equipment. Power is terminated at the main lugs rather than through a factory-installed main breaker within the listed load center configuration.
ABB's product details identify the factory-installed 200A main breaker option as No for all six models listed on this page.
Required upstream overcurrent protection, service equipment configuration, and disconnecting means should be determined by the electrical system design and applicable requirements.
120/240V Residential Distribution
Single Phase
These load centers are designed for single-phase electrical distribution.
3-Wire 120/240V AC
ABB specifies a 1-phase, 3-wire, 120/240V AC service configuration for each PAL model in this product group.
NEMA 1 Indoor Configuration
PAL1612, PAL2012, PAL2412, PAL3012, PAL3020, and PAL4020 are all identified as NEMA 1 indoor load centers.
NEMA 1 equipment is intended for compatible indoor environments. These models should not be substituted for outdoor or higher-environmental-protection enclosures where another NEMA classification is required.
The ABB product information identifies each enclosure as an indoor combination enclosure with a door.
22 kAIC Interrupting Rating
ABB lists an interrupt rating and interrupting capacity rating of 22 kAIC for each of the six PAL load center configurations included on this page.
The available fault current at the installation and the ratings of all associated breakers and electrical equipment should be verified before installation.

Installation & Selection Considerations
- Confirm that a main-lug-only load center is required.
- Verify that the electrical system is single-phase, 3-wire, 120/240V AC.
- Select the required 125A or 200A ampere rating.
- Confirm the required number of spaces and maximum circuit capacity.
- Verify that a NEMA 1 indoor enclosure is suitable for the installation.
- Confirm compatible plug-on neutral breakers separately.
- Verify required upstream overcurrent protection.
- Confirm grounding and bonding requirements for the installation.
- These models do not include a factory-installed ground kit.
- Verify conductor sizing and terminal requirements.
- Confirm that the available fault current does not exceed the equipment rating.
- Maintain required electrical working clearances.
- De-energize equipment before installation or service.
- Verify absence of voltage before working on electrical equipment.
