We've sized panels for every kind of commercial building. Here are the problems our clients call us about most often.
New equipment added without confirming spare panel capacity often pushes a circuit or the entire service past its rated limit. Repeated tripping is a clear sign the load exceeds what the system was designed to carry safely. We calculate actual demand and recommend the right fix, whether that's redistribution or a service upgrade.
Guessing at service size for a panel upgrade risks installing equipment that's either undersized within a few years or oversized in a way that wastes money upfront. Getting this number wrong is expensive to correct after installation. We run a full load calculation before any equipment gets ordered.
Most jurisdictions require a documented load calculation before approving a service upgrade or major equipment addition permit. A missing or incomplete calculation is one of the most common reasons permit applications get sent back. We provide a complete, permit-ready load calculation report.
Commercial landlords often don't know whether an existing electrical service can support a new tenant's specific equipment needs before signing a lease. Committing to a tenant with equipment the building can't support creates costly problems later. We assess existing capacity against the tenant's actual equipment load.
Buildings that have added or removed equipment over the years often have a panel schedule that no longer reflects reality, making any load estimate unreliable. Working from outdated documentation risks a calculation that misses real risk. We conduct an on-site equipment inventory to update the schedule accurately.
Adding solar panels or a backup generator changes how load flows through a building's electrical system and requires a recalculation to confirm interconnection points and capacity limits. Skipping this step can create code violations or unsafe backfeed conditions. We calculate integration requirements before equipment gets installed.
Commercial kitchens run heavy simultaneous loads from ovens, refrigeration, and ventilation that residential-style panels were never designed to handle. This is one of the most common load calculation calls we receive from food service clients. We size the panel specifically around kitchen equipment demand patterns.
Electrical service size needs to be locked in early in a new build's design phase to coordinate with the utility connection and switchgear ordering timelines. Waiting too long to calculate this can delay the entire project. We provide load calculations early enough to keep construction on schedule.
Motor-driven equipment like compressors, pumps, and conveyors draws significantly more current at startup than during normal operation, and a calculation that ignores this can undersize the service. Getting motor load factors wrong creates real safety and reliability risk. We apply proper motor demand factors to every industrial calculation.
We assumed we'd need a full 400-amp service to add our new kitchen equipment, but Electrical Services Ontario ran the numbers and showed our existing 200-amp service had enough spare capacity with the right panel adjustments. Saved us thousands.
We were about to add three new production machines without checking anything first. The technician ran a full load calculation and flagged that we were already close to the panel's limit, which changed our whole equipment rollout plan.
Our building didn't have an updated panel schedule so the process took a day longer than quoted while the technician did an on-site inventory. The final report was detailed and exactly what our engineer needed for the permit application.
We submitted the load calculation report from Electrical Services Ontario with our service upgrade permit application and had zero questions back from the reviewer. That alone saved weeks of back and forth.
I had no idea demand factors could reduce a service size calculation legitimately until this was explained to me. The technician walked through exactly why our office building didn't need the oversized service another contractor had quoted.
Electrical Services Ontario handled the load calculation for our new commercial build early in the design phase, which made coordinating with our electrical contractor and the utility much simpler down the line. Everything lined up when the panel was finally installed.

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.
