When Your Business Has Outgrown Its Electrical Service.
A commercial electrical panel has a fixed capacity. When the equipment, square footage, or load demands of your business grow beyond what it was sized for, the panel becomes a ceiling — one that shows up as tripped breakers, voltage sags, or simply no room to add the circuits your operation needs.
Loch Monster Electric performs a load calculation before recommending any panel work, so the upgrade is sized correctly for where your business is going — not just where it is today. All work is permitted, inspected, and installed to commercial code across the Twin Cities Metro.
When Do You Need
Commercial kitchen equipment, additional HVAC units, EV charging stations, and production machinery all carry significant electrical load. When that load exceeds what your current panel was designed to handle, breakers trip under normal operating conditions — not because something is wrong with the equipment, but because the service feeding it is undersized. We perform a load calculation that accounts for your existing demand and the equipment you are adding, then size and install the upgrade to handle both without leaving your building at its limit again six months from now.
A full panel with no open slots creates pressure to use tandem breakers — two breakers in a single slot — to add circuits. In most commercial installations, this is a code violation, and it is one that creates real risk. Tandem breakers in a panel not rated for them can generate heat and fail to trip correctly under fault conditions. When your panel is out of space, the right solution is a panel replacement or a sub-panel, depending on your building's layout and load. We assess both options and recommend what actually fits your situation — not the quickest fix.
When large equipment starts up — motors, compressors, HVAC systems — it draws a significant surge of current. If your service entrance conductors, connections, or panel are undersized for that demand, voltage drops across the whole building. Lights dim, sensitive electronics behave erratically, and motors that start under low voltage run hotter and wear out faster. We trace voltage sag issues from the equipment back through the conductors to the service entrance, identify where the drop is occurring, and correct it at the source — whether that is the panel, the wiring, or the service itself.

If breakers trip under normal load, you are adding equipment that your current service cannot handle, or you are planning a tenant buildout that requires more capacity, those are all signs. A load calculation tells you exactly where you stand. We do these before recommending any panel work.
A load calculation adds up the electrical demand of everything running in your building and compares it against your service capacity. It tells you whether your current panel can handle what you are asking of it, and it is what we use to size any upgrade correctly. Skipping a load calculation is how you end up with a panel that is too small six months after the upgrade.
If you run large motors, industrial HVAC, manufacturing equipment, commercial refrigeration, or high-capacity machinery, three-phase power is almost certainly the more efficient and cost-effective option. For a standard office or retail space, single-phase is usually sufficient. We look at your equipment list and tell you what makes sense.
Most commercial panel upgrades are completed in one to two days, depending on the size of the service and the condition of the existing installation. We coordinate the utility disconnect in advance and schedule the inspection so there are no unnecessary gaps between the work and the sign-off.
Yes. A properly installed generator connection requires a transfer switch that prevents backfeed onto the utility grid, which is both a safety requirement and a code requirement. We install manual and automatic transfer switches for commercial properties and size the connection to the loads you need the generator to cover.
