Heavy‑Duty Electrical Power, Engineered for Safety, Uptime, and Growth
Your production lines, compressors, and process controls depend on power that is clean, stable, and delivered safely. Legacy Industries designs, installs, commissions, and maintains industrial power systems across Upstate South Carolina, North Georgia, and Western North Carolina. From medium‑voltage distribution and switchgear to PLC/SCADA controls and VFD‑driven motor systems, we build infrastructure that meets rigorous safety and performance targets, day in, day out.

Lifecycle Support
Preventive maintenance, infrared scans, power quality audits, and 24/7 emergency response.
End‑to‑End Industrial Power Delivery
We handle the full stack, from service entrance to controls.
Warehousing & Logistics (high‑bay lighting, conveyors, dock power)
Switchgear, MCCs & Distribution
Main switchboards with proper AIC ratings and future spares
MCC buckets, combination starters, and feeder breakers sized for expansion
Busway and bus plug drops for reconfigurable production floors
Transformers: K‑factor, isolation, and ventilation planning
Comprehensive labeling: arc‑flash, circuit directories, and feeder tags
Lighting for Industrial Spaces
High/Low‑Bay LED with aisle optics and motion/daylight zoning
Task & Inspection Lighting with high CRI for QA areas
Exterior & Security poles and wall packs for yards and perimeters
Emergency & Egress lighting with battery packs and monthly test routines
Safety & Compliance
We build safety into every task:
NEC‑aligned installations with clearances and labeling
NFPA 70E practices: energized work permits, PPE, and LOTO
OSHA compliance: barricades, spotters, and housekeeping
Hazardous‑location equipment where classified (as specified)
Commissioning & Testing
Our commissioning program verifies readiness before turnover.
Test
Purpose
Megger/Insulation Resistance
Confirm cable insulation health prior to energization.
Primary/Secondary Injection
Validate breaker trip curves and relay settings.
Torque Audits
Documented torque on terminations per manufacturer spec.
Infrared Thermography
Identify hot spots under load prior to production.
Functional/IO Tests
Verify PLC/HMI logic, interlocks, and E‑Stop circuits.
Deliverables include test reports, marked‑up one‑lines, and as‑builts.
Shutdown Planning & Phased Cutovers
We coordinate with operations to reduce downtime:
Night/weekend work windows
Pre‑fabricated panel builds and skid assemblies
Clear MOPs (Methods of Procedure) and safety briefings
Preventive Maintenance Programs
Keep systems reliable with scheduled care:
IR scans of switchgear, MCCs, and terminations
Breaker exercising and cleaning; lubrication where allowed
Panel/panelboard inspection and re‑torque
VFD filter service and cooling fan checks
Power quality logging and report reviews
Service Areas
We support industrial facilities throughout:
Greenville
Spartanburg
Anderson
Simpsonville
Laurens
Gaffney
Western North Carolina
North Georgia
Multi‑site and campus programs can be scheduled to align with maintenance shutdowns.
Frequently Asked Questions
Can you work in an active production environment?
Yes. We plan phased cutovers, cordon work zones, and coordinate with supervisors to maintain throughput.
Do you provide stamped engineering drawings?
For design‑build projects, we produce detailed one‑lines and coordination; stamped drawings can be coordinated per project requirements.
Can you integrate new equipment with existing PLCs and HMIs?
Absolutely. We match I/O, protocols, and standards for seamless integration and documented change control.
How do you handle arc‑flash and coordination?
We perform studies, set protective devices, and apply labels per IEEE and NEC guidance to improve safety and selectivity.
What is your lead time for major upgrades?
Lead time varies by gear procurement and shutdown windows; we provide realistic schedules and early ordering to meet targets.
Start with a Purpose‑Built Power Plan
Every plant is unique. Legacy Industries evaluates your current loads, future expansion, and operational risks to create a power plan that supports production, protects people, and simplifies maintenance. From MV service to the last sensor wire, our team delivers industrial electrical work that stands up to demanding environments.
