Construction Details
ABB ReliaHome P-Series+ load centers use copper bus construction and a plug-on neutral design intended to simplify compatible branch circuit breaker installation.
The platform uses a galvanized enclosure with integrated circuit breaker mounting rails, backed-out neutral screws, field-extendable neutral bars, and ABB's one-tool installation approach.
ABB identifies P-Series+ as a single-phase, 3-wire, 120/240 VAC platform available with both main-lug-convertible and main circuit breaker configurations. These four PCM models are listed here as indoor NEMA 1 main breaker load centers.
Factory-installed bonding screws are standard on P-Series+ main circuit breaker configurations.

Selecting the Correct Load Center
100A | 20/40
Select PCM2010 for a 100A indoor NEMA 1 copper-bus configuration with 20 spaces and capacity for up to 40 circuits.
100A | 30/60
Select PCM3010 for a 100A indoor NEMA 1 copper-bus configuration with 30 spaces and capacity for up to 60 circuits.
200A | 30/60
Select PCM3020 for a 200A indoor NEMA 1 copper-bus configuration with 30 spaces and capacity for up to 60 circuits.
200A | 40/80
Select PCM4020 for a 200A indoor NEMA 1 copper-bus configuration with 40 spaces and capacity for up to 80 circuits.
Main Circuit Breaker Configuration
These PCM models use a Main Circuit Breaker (MCB) configuration. The main breaker serves as the primary disconnecting and overcurrent-protection device within the compatible load center assembly.
ABB identifies main circuit breaker as an available P-Series+ configuration and specifies factory-installed bonding screws on main circuit breaker models. :contentReference[oaicite:1]{index=1}
Confirm service ampere rating, conductor size, available fault current, branch breaker requirements, and complete service-equipment configuration before installation.
Copper Bus Construction
ABB identifies copper bus as a defining feature of the ReliaHome P-Series+ family. :contentReference[oaicite:2]{index=2}
Copper bus construction should be considered along with service amperage, conductor requirements, breaker configuration, and project specifications when selecting the complete load center.
Plug-On Neutral Design
Plug-On Neutral Breakers
ReliaHome P-Series+ load centers use plug-on neutral bars designed for compatible plug-on neutral branch circuit breakers. :contentReference[oaicite:3]{index=3}
Accessible Neutral Connections
Elevated neutral bars with backed-out screws and field-extendable neutral bars help simplify compatible conductor installation and future panel expansion. :contentReference[oaicite:4]{index=4}
NEMA 1 Indoor Configuration
All four PCM models in this product group are listed as NEMA 1 indoor configurations.
ABB identifies ReliaHome P-Series+ as available in indoor NEMA 1 and outdoor NEMA 3R configurations. These PCM2010, PCM3010, PCM3020, and PCM4020 variants are intended for compatible indoor applications. :contentReference[oaicite:5]{index=5}
Do not substitute a NEMA 1 enclosure where outdoor weather protection or a higher environmental enclosure rating is required.
