Short answer

What the job involves

What commercial electrical service involves

Commercial calls split into two kinds. Emergencies, like a dead register circuit, a tripped main or lights out on a sales floor, need power restored quickly and safely, then a proper repair. Planned work, like new equipment, added circuits or a layout change, needs a schedule that keeps the business running.

Commercial spaces often run on three-phase power, have panels shared with other tenants, and answer to a landlord's rules. We work within all three, document what we did for the landlord or insurer, and flag anything that should be planned before it fails. For a full build-out of a new space, see tenant fit-outs.

Common versions of this job

Three kinds of commercial work

Office Electrical Service

Floor box outlets being installed in an open-plan office

Offices need circuits that match how people work: enough outlets at each workstation, dedicated circuits for kitchens and copy rooms, and lighting that suits screens. We add and relocate outlets for new layouts, fix tripping circuits, and trace faults in older office panels where labels no longer match the floor plan. Work is done after hours or floor by floor, and the panel directory is updated so the next tenant change is easier for whoever handles it, whether that is us or the landlord's own contractor.

Retail and Storefront Power

In a store, power has to reach registers, displays, signs and lighting that change with every season's layout. We add circuits for new displays, repair sign and window lighting, and fix faults that take down part of the sales floor. When a problem starts during business hours, we restore what can be restored safely first so the store can keep selling, then return before opening to finish the permanent repair without customers in the aisles, and we label the circuits that feed each display.

Three-Phase Equipment Circuits

Checking phase rotation at a three-phase disconnect

Larger equipment, like commercial refrigeration, compressors, some kitchen appliances and machinery, often runs on three-phase power. Connecting it means matching the voltage and phase rotation, sizing the circuit and disconnect to the nameplate, and confirming the motor turns the right direction before the equipment is loaded. We work from the equipment's installation manual, and we check that the panel serving it has the capacity before the equipment arrives, so installation day is spent connecting it rather than waiting on a panel.

Included in the visit

What commercial service includes

  • Answering 24/7 for faults that stop the business

  • Three-phase connections tested for rotation
  • Updated panel directory
  • Written summary for the landlord or insurer
Local conditions

Commercial work at city rates

Coastal markets like New York City run 20 to 40 percent above national electrician rates, and most contractors carry a minimum charge on service calls. For a business, that makes planning worth money: grouping small repairs into one scheduled visit, fixing recurring faults properly rather than resetting breakers, and adding capacity before new equipment arrives. Emergency calls are always answered, but planned work costs less and is easier to fit around the hours a store or office is open to customers.

Timing

Keeping downtime short

Emergency visits focus on restoring power safely, which is usually faster than the full repair. The permanent fix is then scheduled for before opening, after closing or on a quiet day. For planned work, we agree the working window with you in advance and stage parts ahead of time, so the work fits the window rather than stretching into business hours.
