Description

QO Loadcentres offer premium features by allowing QO breakers, ground fault interrupters, arc fault interrupters, and surge arresters to be installed inside. QO Loadcentres are designed for residential and industrial use to protect electrical systems, equipment, and people. They are available in both traditional and plug on neutral configurations. There is 3 types of mains available. There is main circuit breaker, main lugs, and generator panel. Single and three phase options are available. The bus bars are tin plated copper and are shielded. Indoor and outdoors enclosures are an option. QO Loadcentres enable the use of a full complement of accessories. This 1 phase loadcentre has 40 spaces and 54 circuits. This system provides 100A main breaker in a NEMA 1 enclosure. It also includes plug on neutral, combination cover, and is CSA rated.

Features

Offering an extensive 40-space chassis that expands up to 54 single-pole circuits using space-saving tandem breakers, this 100-amp load center delivers massive circuit density within a single enclosure. It ensures your infrastructure easily accommodates heavy modern loads like EV charging stations, heat pumps, hot tubs, and multi-room additions without requiring the extra footprint or expense of a secondary sub-panel.
Equipped out of the box with a robust 100-amp, 2-pole main circuit breaker boasting a 22 kA short-circuit current rating (AIR), this convertible interior provides immediate, ultra-reliable overcurrent and short-circuit protection. It functions perfectly as a dedicated sub-panel or main service entrance device for residential homes and light commercial settings, safely interrupting catastrophic faults before they damage downstream appliances or electronics
Built with high-conductivity, tin-plated copper busbars that are fully shielded to maximize worker safety during routine maintenance, this panelboard provides low-resistance electrical pathways. The specialized plating strongly resists the oxidation and terminal overheating common with lower-grade aluminum bus designs, ensuring stable 120/240V power delivery and long-term system reliability
This indoor-rated, welded sheet steel load center includes a grey baked-enamel combination cover engineered for both flush-mount drywall installations and surface-mount basement walls. The split neutral bars allow for exceptionally tidy, code-compliant wire routing, while factory-backed out screws on the ground and neutral terminals let residential electricians hook up branch lines and pass strict CSA electrical inspections in record time.
