Switchgear replacement and upgrades

Plan the equipment and the installation together. We replace and upgrade switchgear, switchboards and disconnects for commercial and multifamily properties, with attention to capacity, access and the people who depend on the power.

Equipment replacement starts with the system

A switchgear project can involve the main disconnect, distribution equipment, metering sections and associated panels. We review the existing installation and the proposed work with the property team. Equipment ratings, connections, space and the route into the electrical room all affect the scope.

Lynwood veterinary hospital: electrical renovation

Our scope at this Lynwood veterinary hospital covered electrical work throughout the facility: examination rooms, surgical rooms and equipment booms, X-ray and laboratory equipment, waiting areas and exterior lighting. The 600A single-meter service equipment is shown above.

Coordinate the work around an occupied property

Tell us who uses the building, which equipment must be considered and who manages access. We coordinate with the utility, engineer, property manager and other trades as the project requires. Shutdown timing and any temporary power arrangement are assessed before the installation sequence is agreed.

Thermal inspection can support the assessment

We have our own thermal imaging equipment and can discuss including a thermal inspection in the project. The proposal identifies the inspection scope and any additional testing or specialist services. A thermal image is one part of an assessment; it does not establish the condition of every component or guarantee that equipment is free of defects.

Related distribution work

Our multifamily work includes switchgear, disconnects and associated house subpanels. We coordinate equipment replacement with the people responsible for the property, the engineer and the utility where the scope requires it.

Electrical work across 14 buildings and a clubhouse

The completed Culver City project covered 532 meters total and approximately 350 in-unit subpanel replacements. The scope included 600A single-phase 120/240V section disconnects and 15 400A three-phase switchgear assemblies for common areas and elevators.

Common questions

Will the building need to lose power?

The required isolation depends on the system and the work. Some projects may be staged, while others need a complete shutdown. We review the affected loads, utility steps and reconnection requirements before confirming the plan.

Can you replace associated subpanels and meter equipment?

Yes. Our work includes multi-meter equipment, disconnects, switchgear and subpanels. We assess which parts belong in the replacement scope and coordinate the work as a project.

What should we provide for an initial discussion?

Share the property city, the reason for the work, available drawings, equipment records and any utility correspondence. Photos taken from a safe, accessible position can help. Please do not open energized equipment to take photographs.

Technical planning notes & references

BEFORE WE QUOTE THE WORK

Distribution equipment needs a coordinated specification

Match ratings to the system

Service voltage and phase, bus rating, available fault current, interrupting ratings and protection arrangements need review together. Physical fit is only part of compatibility. Equipment records help, but field verification establishes what is actually being changed.

Plan access and shutdowns

Working space, rigging access, cable routes and the isolation sequence can shape the project. Check replacement-equipment lead times before scheduling a shutdown. Define testing, settings, labeling and turnover information with the project team.
