Understanding Commercial Electrical Panels: Types and Basics

Delving deeply into understanding commercial electrical panels equips business owners and facility managers with the knowledge to make informed decisions about their electrical infrastructure, as these systems form the backbone of safe and reliable power distribution in commercial settings, handling significantly higher loads and complexities compared to residential counterparts. A commercial electrical panel, commonly known as a distribution panel, circuit breaker distribution panel, or service panel, acts as the central control point where incoming power from the utility is divided into circuits for various building functions, such as lighting, machinery, HVAC systems, and specialized equipment. In the context of the 2025 CEC updates, which emphasize enhanced safety protocols like mandatory arc-fault circuit interrupters (AFCIs) and ground-fault circuit interrupters (GFCIs) for high-risk areas, commercial panels must be designed to withstand continuous operation under demanding conditions, preventing hazards like electrical fires or downtime that could cost businesses thousands in lost productivity.
What Voltages Are Used in a Commercial Electrical Distribution Panel?

120/208V three-phase

In Canadian commercial applications, standard voltages include 120/208V three-phase for general office and retail environments where balanced power is needed for lighting and appliances

347/600V

347/600V for industrial settings requiring higher power for motors and heavy equipment

120/240V single-phase

120/240V single-phase for lighter loads in smaller commercial spaces, all while maintaining voltage drop limits of no more than 3% on feeders and 5% overall per CEC guidelines to ensure efficient energy delivery without excessive heat buildup.

Standard commercial electrical panel types are selected based on the specific needs of the business, factoring in ampacity, phase requirements, and environmental conditions like Vancouver Island's moisture-prone climate, which demands corrosion-resistant enclosures:

Sub Panels and Pony Panels

Act as extensions to the main commercial electrical panel for decentralized power in large buildings, such as adding a 100-200 amp sub panel in a remote workshop or storage area; wiring electrical sub panel involves feeder cables at $6-$15 per foot, with total costs of $2,000 to $5,000 per unit. These allow for isolated circuit management without overloading the primary system, aligning with CEC rules for separation to enhance fault isolation—experience-based diagnostics indicate that poor feeder sizing causes 25% of sub panel failures, corrected through ampacity-matched conductors and proper grounding bonds.
