Manufacturing Business Needed More Power

Metering Reconfiguration and Process Power Feed — "Power Where Production Needs It"

The customer needed reliable, flexible power to support a new manufacturing process area. We tapped into the existing metering gear, reconfigured the metering arrangement to free the required capacity, and ran a 300-foot sub-feeder to the designated production zone. Multiple step-down transformers and new distribution panels were installed so the customer could supply equipment at 277/480 V or 208 V as required. Branch circuits were routed to each machine and work cell, enabling the new line to start production without disruption to the rest of the facility.

Property Improvements

Seamless startup of the new manufacturing process area with power available at required voltages.
No significant production downtime for the wider facility during installation.
Flexible infrastructure supporting both 277/480 V and 208 V equipment, reducing future retrofit costs.
Clean handoff: as-built drawings, single-line updates, testing reports, and operator guidance delivered for maintenance and future expansions.

To round out the project, we delivered a clear one-page brief that included updated single-line drawings and a simplified feeder routing diagram for the customer’s internal records. We also prepared a sales-ready summary highlighting the added capacity, installation timeline, and new voltage flexibility. For the operations team, we provided a practical handoff package that included a transformer and panel map, a recommended maintenance checklist, and guidance on spare parts to ensure the new infrastructure stays reliable and easy to service as production grows.

Project Details

Client: Large Tempe-based manufacturer (one of the state’s largest)
Location: Tempe, AZ
Facility: 80,000 sq ft existing manufacturing building
Scope: Reconfigure existing metering equipment; pull power from existing meter bank; install 300 ft sub-feeder conduit and circuitry; install multiple panels and step-down transformers; distribute branch circuitry to all new process equipment
Power options provided: 277/480 V and 208 V distribution

Project Highlights

Metering reconfiguration: Coordinated load studies and metering changes to safely extract additional capacity from the existing bank.
300 ft feeder run: Trench/conduit routing and pull-schedule executed to minimize impact on plant operations and logistics flow.
Transformers and panels: Staged and installed multiple step-down transformers to provide dual voltage options; panels configured for balanced distribution and future expandability.
Branch circuitry: Dedicated distribution to individual machines and panels with labeled, test-certified terminations for commissioning.
Coordination with plant ops: Work windows and lockout/tagout procedures aligned with production schedules to avoid downtime.
