Same trade, different job

Wire, breakers and code apply to both. What changes on a commercial job is the size of the equipment, the power coming in and how the work gets scheduled around a business that needs to stay open.

Where they differ

Here are the main differences we plan for.

ResidentialCommercial
PowerUsually single-phaseOften three-phase
PanelsOne main panel, maybe a subpanelMultiple panels and distribution equipment
Wiring methodsMostly cable in wallsMore conduit and exposed runs
LightingFixtures and fansHigh-bays, emergency and exit lighting, controls
SchedulingAround the familyAround business hours and other trades

Keeping the business running

Most commercial owners care most about downtime. We plan shutdowns ahead, do what we can with power on, and schedule outages for early mornings, evenings or weekends when that's what the job needs.

New commercial builds

On new builds we work with the general contractor from the plans through final inspection, covering service, panels, lighting, receptacles and equipment connections.

Talk it through

Whether it's a single circuit for a new machine or a full shop build, call and tell us what you're working on. We'll come look and quote it plainly.
