Commercial electrical systems are rarely designed with unlimited growth in mind. As businesses evolve, power demands increase — often faster than expected. Without proper planning, facilities may face unsafe load conditions, unplanned downtime, or rushed upgrades that disrupt operations. In Hamilton & Halton, many commercial properties outgrow their original electrical layouts within a few years.

What Electricians Review When Planning Power Distribution

• Current and projected load: Evaluating existing demand and estimating future equipment requirements.
• Panel and feeder capacity: Confirming whether panels, transformers, and feeders can handle expansion.
• Circuit layout: Identifying opportunities to balance loads and reduce single-point stress.
• Equipment startup loads: Accounting for inrush current from motors, compressors, and machinery.
• Code and ESA compliance: Ensuring expansions meet commercial electrical standards.

Smart Electrical Upgrades That Support Business Growth

1. Add sub-panels to distribute loads efficiently and simplify future expansions.
2. Upgrade service size when approaching panel or feeder limits.
3. Install dedicated equipment circuits for new machinery or technology.
4. Balance phases to reduce voltage drop and overheating.
5. Plan spare capacity so future upgrades don’t require major rewiring.

Typical Cost Range for Power Distribution Improvements

Smaller upgrades such as sub-panels, new circuits, and load balancing typically range from $800–$3,000. Larger projects like service upgrades, feeder replacements, or multi-panel expansions often range from $4,000–$15,000+, depending on building size and electrical complexity.
