Preventive Electrical Maintenance Plans


Stay Ahead of Breakdowns with Routine Electrical Inspections & Proactive Care

Electrical systems work quietly—until they don’t. Legacy Industries delivers structured preventive electrical maintenance plans for homes, commercial spaces, and industrial facilities across Upstate South CarolinaNorth Georgia, and Western North Carolina. Our licensed electricians inspect, test, and service panels, wiring, lighting, controls, and backup power so you avoid surprise outages, equipment damage, and safety hazards.


Why Preventive Maintenance?

Risk Without PMTypical OutcomeHow Our Plans Help
Loose terminations & heat buildupNuisance trips, arcing, firesTorque auditing, infrared (IR) scans, re‑termination
Aging breakers & panelsUnreliable protection, downtimeBreaker testing, panel health checks, labeling
Overloaded circuitsMelted insulation, equipment failureLoad balancing, circuit mapping, capacity planning
Poor grounding/bondingShock risk, erratic controlsGrounding verification, corrective bonding
Unmanaged lightingHigh energy spend, dark spotsLED upgrades, controls calibration, schedule tuning
Neglected backup powerNo‑start in outagesATS exercise, battery checks

Proactive service reduces emergency calls, protects assets, and keeps operations running smoothly.


Plan Tiers to Fit Your Site

We offer three customizable tiers—each with documented checklists and photo‑verified reports.

PlanBest ForFrequencyHighlights
EssentialHomes, small officesSemiannualVisual inspection, panel torque check, GFCI/AFCI testing, outlet/switch sampling, smoke/CO detector review, light fixture checks

Every plan includes a written report with findings, priorities (Critical/High/Medium/Low), and recommendations.


Core Checklist Items

Panels & Distribution

  • Inspect main and subpanels for heat, corrosion, and moisture
  • Torque verify lugs and breakers to manufacturer spec
  • Check labeling, directory accuracy, and spare capacity
  • Inspect grounding electrode conductor and bonding jumpers
  • Evaluate surge protection devices and indicator status

Circuits & Devices

  • Test GFCI/AFCI where installed
  • Sample outlets and switches for secure mounting and proper polarity
  • Inspect cord caps, extension usage, and workplace practices
  • Verify dedicated circuits for appliances, IT, and equipment

Lighting & Controls

  • Verify emergency/egress lighting and exit sign function
  • Replace failed lamps/boards; clean lenses where accessible
  • Tune occupancy sensors, timeclocks, and daylight zones
  • Recommend LED retrofits where savings/visibility justify

Motors & Equipment (Commercial/Industrial)

  • Inspect feeders to AHUs, pumps, compressors, and process equipment
  • Check overload settings and starter/VFD cooling
  • Verify local lockable disconnects and signage

Backup Power (Optional Add‑On)

  • Inspect battery/charger, coolant/oil levels, block heater
  • ATS exercise for transfer and re‑transfer timing
  • Recommend annual load‑bank testing where applicable

Infrared (IR) Thermography

IR scanning reveals hot spots long before failure. We scan:

  • Main switchboards, panelboards, MCCs
  • Breakers, lugs, bus connections
  • Transformers and terminations
  • Drives and control cabinets

Deliverables: annotated thermal images, temperature deltas, and corrective actions ranked by severity.


Power Quality & Load Management

Unstable power shortens equipment life and trips controls. Our team can log and analyze:

MetricWhy It Matters
Voltage imbalanceReduces motor life; causes overheating
Harmonics (THD)Affects VFDs, transformers, and controls
Inrush and demand peaksTriggers breaker trips; signals need for sequencing
Power factorImpacts utility charges, transformer loading

We propose fixes such as phase rebalancing, harmonic filtering, VFD tuning, or staged starting.


Residential Preventive Maintenance

Keep your home safe and efficient with routine checks tailored to family life.

  • Panel and breaker health review
  • GFCI/AFCI testing in kitchens, baths, laundry, garage, and exterior
  • Surge protection evaluation for electronics and appliances
  • Smoke/CO detector placement and battery checks
  • Exterior/landscape lighting inspection

We also identify opportunities for LED conversions and smart controls to reduce bills and improve comfort.


Commercial Preventive Maintenance

Business continuity depends on reliable power. Our commercial PM reduces risk and supports compliance.

  • Quarterly IR scans of panels and critical feeders
  • Exit/egress lighting verification with log sheets
  • Outlet/device testing in high‑use areas (break rooms, copy rooms, POS)
  • Surge protection and UPS interface checks (owner‑provided UPS)
  • Lighting control schedules for business hours and cleaning crews

Industrial Preventive Maintenance

Factories and warehouses face higher electrical stress. Our Enterprise plan addresses these realities.

  • MCC bucket inspection and breaker exercising
  • VFD filter and fan checks; cabinet housekeeping
  • Motor rotation/amp check sampling under load
  • Transformer temperature and ventilation review
  • Coordination/arc‑flash label review; update notes for engineering

Documentation & Compliance

Every visit concludes with a clear PM report:

  • Checklist results and photos
  • Thermal images (when included) with temperature deltas
  • Measured values (voltage, current, imbalance) where logged
  • Corrective action list, parts recommendations, and priorities
  • Date of next service and suggested intervals

For AHJ or insurance needs, we can align logs to requested formats.


Scheduling Around Your Operations

We minimize disruption with flexible options:

  • Night/weekend service windows
  • Phased floor‑by‑floor or area‑by‑area checklists
  • Temporary lighting/power when required
  • Clear site safety plans with barricades and signage

Add‑On Services

  • Thermal Imaging Program: Semiannual IR with trending
  • Lighting Optimization: Sensor recalibration and scene programming
  • Surge Protection Upgrade: Panel‑level TVSS installation and testing
  • Labeling & Directories: Panel schedules, circuit directories, and equipment labeling

Service Areas

Preventive maintenance plans available across:

  • Greenville
  • Spartanburg

We coordinate calendars to match your production cycles and business hours.


Frequently Asked Questions

How often should I schedule electrical PM?

Homes: semiannual. Commercial: quarterly. Industrial: monthly visual with quarterly PM, plus annual IR and power quality review.

Will PM interrupt operations?

Briefly in certain areas. We schedule off‑hours or phase work to avoid downtime wherever possible.

What if you find a critical issue?

We flag it immediately, make safe, and—when authorized—perform repairs or schedule expedited service.

Do you track service history?

We maintain logs by location and panel, with reminders for upcoming intervals.
