Power Distribution
The Power Your Equipment Was Designed For.
Three-phase power delivers electricity in three alternating currents instead of one, which is how most commercial motors, compressors, and industrial equipment are engineered to operate. Running that equipment on single-phase power forces it to work harder, draw more current, and generate more heat than it was designed to handle.
Loch Monster Electric coordinates three-phase service installations and conversions across the Twin Cities Metro — working directly with Xcel Energy and other utilities to bring the right service to your facility and wire your equipment correctly from the start.
When Do You Need
Industrial motors, large air compressors, commercial refrigeration systems, CNC machinery, and commercial HVAC units are typically designed and rated for three-phase power. Attempting to run them on single-phase service is not just inefficient — in many cases it is not possible without a phase converter, which introduces its own reliability and warranty complications. We assess your equipment list, confirm the service your facility needs, coordinate the utility upgrade, and wire everything to the new service — so your equipment runs the way it was designed to, without workarounds that create problems down the line.
Converting an existing building to three-phase service is not simply a panel swap. It requires a new service entrance sized for the increased capacity, coordination with the utility to bring three-phase conductors to your building, a new distribution panel, and updated wiring to each piece of equipment that will use it. We manage the entire process — utility coordination, permitting, installation, and inspection — and document everything required for the utility interconnection. You get a complete, code-compliant installation without having to manage multiple contractors or track down paperwork after the fact.
A motor pulling more current than its nameplate rating is a motor under stress. On single-phase service, three-phase motors either cannot start at all or must use a phase converter that approximates the third leg of power. That approximation creates a voltage imbalance across the motor windings, which generates excess heat, reduces efficiency, and shortens the motor's service life significantly. If your motors are running hot, tripping thermal overloads, or your utility bills reflect higher consumption than expected, the underlying cause may be a power supply mismatch rather than a mechanical problem. Proper three-phase service eliminates the imbalance at the source.

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.
