We've helped businesses move past every version of this power limitation. Here are the situations our commercial clients call us about most often.
Large motors, industrial compressors, and commercial HVAC units often require a steady 3-phase supply that single-phase service simply cannot deliver. Trying to run this equipment on the wrong power type causes overheating, tripped breakers, or motor failure. We assess your equipment specs and design a 3-phase installation that matches the actual load.
Adding new machinery, a second production line, or expanded refrigeration often pushes a facility past what its existing electrical service can support. Delaying the upgrade can stall equipment purchases and hold up the entire expansion timeline. We calculate the new load and install service sized for both current needs and near-term growth.
Many business owners assume they need 3-phase power without confirming it against their actual equipment list. Installing more capacity than necessary adds real cost with no operational benefit. We run a proper load assessment and give a straight answer before recommending any installation.
Repeated tripped breakers during equipment startup usually mean the electrical service is undersized for the load being drawn. Continuing to reset breakers instead of addressing the root cause risks damaging sensitive equipment over time. We evaluate the panel and service size and recommend the right capacity fix.
Upgrading to 3-phase power often requires scheduling with the local utility for a service connection or transformer upgrade, and that process is unfamiliar territory for most business owners. Managing utility scheduling alongside daily operations adds unnecessary stress. We coordinate directly with the utility so the business owner isn't left navigating that process alone.
Business owners often delay a necessary power upgrade out of concern for lost operating hours during the switchover. Postponing the work only extends the period of running on inadequate power. We schedule the final connection during off-peak hours to keep disruption to a minimum.
Ontario requires an Electrical Safety Authority permit and final inspection for any 3-phase installation, and missing a step can delay energizing the new service. Skipping proper permitting risks a failed inspection that stalls the whole project. We pull the permit and manage the inspection process as part of the installation.
Older commercial buildings sometimes have electrical rooms too small or improperly configured for modern 3-phase panels and switchgear. Working around this constraint without a proper plan can lead to code violations or a rushed installation. We assess the space during the site visit and plan panel placement that meets clearance and code requirements.
Commercial 3-phase power comes in multiple voltage options, and selecting the wrong one can mean equipment that runs inefficiently or doesn't work at all. This mismatch often isn't caught until after equipment is already purchased. We match voltage selection to your actual equipment specifications before any installation begins.
Our shop had been stuck on single-phase for years and it was limiting what equipment we could buy. Electrical Services Ontario handled the utility coordination and panel upgrade without a hitch, and we were running our new CNC machine within the week.
The actual installation from Electrical Services Ontario went smoothly but the utility transformer upgrade added about two extra weeks to the project. The crew explained upfront that this part was out of their hands, and once the utility work was done the panel changeover took less than a day.
I assumed we needed a much bigger service than we actually did. The technician ran a proper load calculation and recommended a smaller, less expensive setup that still covers our commercial kitchen equipment with room to grow. Appreciated the honesty.
We were worried about losing a full day of business during the changeover. The team scheduled the final connection for a Sunday morning and had everything back online before we opened. Barely noticed it happened.
I called Electrical Services Ontario assuming I'd need to sort out the permit and inspection myself on top of everything else. They pulled the permit, scheduled the inspection, and kept me updated at each step. One less thing to worry about.
I had no idea there were different 3-phase voltage options until the technician walked me through 208V versus 600V for our facility's equipment. He explained the tradeoffs plainly and didn't push the more expensive option when it wasn't necessary for our load.

Tell us what is happening — no power, a breaker that will not reset, or a planned upgrade. We talk it through and book a time that works for you, including same-day for urgent calls.
A licensed electrician looks at the actual panel, circuit, and load rather than quoting over the phone, then gives you a firm written price with the scope set out line by line.
The electrician who quoted the job does the work. Drop sheets go down, permits are filed where the work calls for it, and you get an update before anything changes from the plan.
Every circuit is tested before we close the panel, the inspection is booked and the certificate handed over, and our labour is warrantied for two years.
