Power matched to your equipment.

Three-phase electrical

A new machine, compressor, or HVAC unit needs more than an empty breaker space. Review its supply requirements, the building distribution, and the route between them before installation.

The details that shape the project.

Before defining the work, we review how your property operates and what the equipment needs.

Start with the nameplate
Collect voltage, phase, current, and the manufacturer installation documents. Similar machines may have different supply requirements.
Trace the source
Confirm the service configuration and distribution path. The building address or panel appearance does not establish compatibility.
Plan the startup
Coordinate energization, rotation checks where applicable, and equipment startup with the machine or mechanical contractor.
A documented path to connection
The assessment identifies the available source, equipment requirements, feeder route, disconnects, and any utility or transformer questions still unresolved. Agree on shutdowns and electrical checks before equipment delivery; vendor startup remains a separately identified responsibility.

A useful starting point.

Send what you have. These details help us prepare for your three-phase electrical project.

Common questions.

Can every building supply three-phase power?

Availability must be confirmed with the serving utility and the existing building equipment. Internal electrical work does not by itself create utility three-phase service.

Are 208V and 480V interchangeable?

No. Equipment and distribution must be matched to their rated supply. Any transformation or replacement is part of the design review.

Does this include machine commissioning?

The proposal should separate electrical installation and checks from manufacturer startup, programming, or process commissioning.

Help with the cost.

Match the project address and electricity provider to the program. We can discuss the electrical scope; the program administrator confirms eligibility, available funding, and the award.

Equipment and application specific

PG&E lists efficiency incentives for qualifying process fan, blower, and industrial pump VFD applications. Have the program review your equipment and operating conditions before ordering. A motor repair or three-phase service installation alone does not establish eligibility.
