Power Distribution System
Reliable Power Distribution System Design in the Greater Toronto Area
Electricity powers every part of your building, from the lights and elevators to data centers and life safety systems. At Bold Engineering, we design safe, efficient, and scalable power distribution systems in the GTA that match your facility’s real needs. If you’re planning a new build or upgrading aging infrastructure, our specialists are here to guide your power distribution design every step of the way.
Power Distribution System Design
Our team develops detailed power distribution design plans that connect the utility supply to your equipment and systems. We calculate load demands, coordinate breaker sizes, and design distribution from the main switchgear through to panels and branch circuits. Every project includes fault current analysis, grounding, arc flash review, and service entrance planning.
We work on high-rise residential, commercial, industrial, and institutional facilities across Ontario.
Main Service & Switchgear Design
Your building’s main service is the heart of its electrical system. We design switchgear layouts that meet utility requirements and building needs, considering future expansion, access, redundancy, and voltage transformation. Whether you need a 600V main switchboard or low-voltage distribution for a smaller site, we’ll configure the equipment and specifications you need. We’ll coordinate with utilities and contractors to avoid conflicts and delays during connection and inspection.
Sub-Distribution & Panelboards
From electrical closets to tenant spaces, our engineers specify how power flows throughout your building. We design layouts for lighting panels, receptacle panels, HVAC loads, and specialized systems. We balance the loads, route conduits, and size equipment based on usage and code.
We also account for safety clearances, accessibility, and space limitations so your system is both code-compliant and easy to maintain.

Frequently Asked Questions
Here are some commonly asked questions about our power distribution system services. If you don’t see your question here, get in touch and we’ll provide you with an answer.
It’s the network of electrical components that delivers electricity from the main service entrance to every load in your building. This system includes panels, breakers, feeders, and protective devices that help maintain safe and reliable power throughout your facility.
Load calculations, equipment sizing, breaker coordination, grounding, panel layout, and circuit routing. We also consider operational needs, energy efficiency, and code compliance during the design process.
Yes, in Ontario, electrical systems must be designed by a licensed engineer to meet building code and utility requirements. This also helps avoid safety hazards and costly rework during inspections.
We’ll calculate demand loads based on building type, use, and occupancy, then size the service, switchgear, and panels to match. We also consider future expansion or equipment upgrades when determining service capacity.
Yes, we often include capacity for future loads or tenants to reduce upgrade costs later. This helps your building adapt to growth without requiring a complete system redesign.
Main distribution connects the building to the utility; sub-distribution delivers power to internal areas like floors, units, or systems. Sub-distribution panels help localize circuit management and make maintenance easier.
We submit drawings, attend meetings, and work with utility reps to align your service entrance with their connection requirements. This coordination helps avoid delays and unexpected costs during construction.
Yes, we include short circuit, coordination, and arc flash analysis as part of our electrical safety documentation. These studies help protect your staff and equipment while meeting workplace safety requirements.
Sometimes. We’ll inspect them and check load capacity, condition, and code compliance before making a recommendation. This can help you save costs if the existing equipment is in good condition and meets current standards.
