Construction Details
ABB ReliaHome P-Series load centers use galvanized enclosure construction with integrated circuit breaker mounting rails and a plug-on neutral design intended to simplify compatible branch breaker installation.
The standard P-Series uses aluminum bus bars and is designed for single-phase, 3-wire, 120/240 VAC residential electrical distribution.
ABB also incorporates elevated neutral bars with backed-out neutral screws, field-extendable neutral bars, and a one-tool installation approach into the ReliaHome P-Series platform.
A factory-installed bonding screw is standard on main circuit breaker ReliaHome P-Series configurations.

Main Circuit Breaker Configuration
These PAM models use a Main Circuit Breaker (MCB) configuration. The main breaker provides the primary disconnecting and overcurrent-protection function for the compatible load center assembly.
ABB identifies main circuit breaker configurations as part of the ReliaHome P-Series offering and specifies factory-installed bonding screws on main circuit breaker models.
Confirm the required service rating, available fault current, conductor size, branch breaker requirements, and complete service-equipment configuration before installation.
Plug-On Neutral Design
Simplified Breaker Connections
The ReliaHome plug-on neutral design provides a dedicated neutral connection system for compatible plug-on neutral branch breakers.
Accessible Neutral Bars
Elevated neutral bars, backed-out neutral screws, and field-extendable neutral bars help provide easier conductor access and installation flexibility.
Aluminum Bus Construction
ABB identifies the standard ReliaHome P-Series as using aluminum bus bars. Copper bus construction is available in the separate P-Series+ family.
The bus material should be considered along with service amperage, breaker configuration, conductor requirements, and project specifications when selecting the complete load center.
NEMA 1 vs. NEMA 3R
NEMA 1 Indoor
