Electrical Load Studies

Electrical Load Studies & Power Monitoring – Phoenix, AZ

Electrical load studies provide the real data you need to make confident decisions about your facility’s power systems. Phoenix Contracting Services conducts comprehensive load studies and power monitoring for commercial, industrial, and multi-family properties throughout the Phoenix metro area. Our studies measure actual electrical demand over time, analyze power quality, and deliver the documentation insurance carriers, engineers, and code officials require.

Whether you’re planning a facility expansion, upgrading electrical service, or responding to an insurance requirement, our load studies give you accurate answers. We track voltage, amperage, power factor, and demand patterns to identify capacity issues, power quality problems, and code compliance gaps before they become costly failures or safety hazards.

When Your Facility Needs a Load Study?

  • Your insurance carrier requires load documentation before approving panel upgrades or renewing your policy
  • You’re adding equipment or expanding operations and need to verify your electrical service can handle the increased demand
  • An engineer, architect, or authority having jurisdiction (AHJ) has requested actual demand data for a permit or code compliance review
  • You’re experiencing nuisance tripping, voltage fluctuations, or unexplained power quality issues
  • You need to size a backup generator, UPS system, or emergency power source accurately
  • You’re planning electrical service upgrades and want to avoid over-sizing (or under-sizing) your investment
  • NFPA 70B compliance requires documented electrical maintenance and testing for your facility

Our Load Study & Power Monitoring Services

Core Load Study Services

30-Day Electrical Load Study

Our most comprehensive service. We install monitoring equipment that records your facility’s electrical usage continuously for 30 days, capturing peak demand, daily cycles, and load variations across all operating conditions. Ideal for insurance requirements, major upgrades, and NFPA 70B compliance.

Load Calculation Services

We perform detailed electrical load calculations based on NEC requirements, equipment schedules, and actual usage patterns. Required for service upgrades, new construction, and permit applications. Our calculations ensure your electrical system is properly sized for safety and efficiency.

Power Load Monitoring & Recording

Continuous monitoring of your electrical systems to track demand patterns, identify peak usage times, and document actual load behavior. We provide detailed recording services for short-term troubleshooting or long-term analysis.

Power Quality Analysis

Comprehensive testing and analysis to identify power quality issues that damage equipment, cause downtime, and increase operating costs. We measure harmonics, voltage disturbances, transients, and power factor to pinpoint problems and recommend solutions.

Energy Audits

Detailed analysis of your facility’s energy consumption patterns to identify waste, reduce costs, and support sustainability goals. We provide actionable recommendations for energy savings and efficiency improvements.

Load Calculations & NEC Compliance 

NEC Load Calculations

Code-compliant load calculations per NEC Article 220 for service sizing, feeder sizing, and panel schedules. Required for permit applications and service upgrades. We ensure your calculations meet local AHJ requirements.

Demand Factor Studies

Determine the actual demand factor for your facility based on real usage patterns rather than theoretical calculations. Helps optimize service sizing and avoid over-investing in electrical infrastructure.

Power Monitoring & Recording

Single-Phase Monitoring

Specialized monitoring for single-phase electrical systems common in smaller commercial buildings, retail spaces, and residential applications. Track voltage, current, and power factor on 120V and 240V systems.

Three-Phase Monitoring

Comprehensive monitoring for three-phase industrial and commercial electrical systems. We track all three phases, neutral current, voltage balance, and phase-to-phase relationships to identify imbalances and inefficiencies.

Energy Usage Analysis

Detailed breakdown of where and when your facility uses energy. We identify peak demand charges, time-of-use patterns, and opportunities for demand reduction and cost savings.

Power Quality Analysis

Harmonic Distortion Analysis

Identify and measure harmonic distortion caused by variable frequency drives, LED lighting, and other non-linear loads. Harmonics damage equipment, cause overheating, and create nuisance tripping. We measure Total Harmonic Distortion (THD) and recommend filtering solutions.

Voltage Sag/Swell Analysis

Document voltage sags (dips) and swells that damage sensitive equipment and disrupt operations. We track voltage variations over time, identify causes, and recommend solutions like voltage regulators or UPS systems.

Transient & Surge Analysis

Capture and analyze electrical transients and surges that cause equipment failure. We identify sources of transients—whether from utility switching, lightning, or internal equipment – and recommend surge protection solutions.

Industry-Specific Studies

Commercial & Industrial Power Studies

Specialized load studies for office buildings, retail centers, warehouses, distribution facilities, and manufacturing plants. We understand the unique electrical demands of commercial and industrial operations.

Hospital Power Studies

Healthcare facilities have critical power requirements and strict code compliance needs. We conduct load studies that address emergency power, critical branch circuits, and NEC Article 517 requirements for healthcare facilities.

Data Center Power Studies

Data centers require precise power monitoring for capacity planning, PUE optimization, and uptime assurance. We provide detailed analysis of power distribution, redundancy, and efficiency for mission-critical IT infrastructure.

Manufacturing Facility Studies

Industrial facilities with heavy machinery, motor loads, and process equipment require specialized load analysis. We account for motor starting currents, three-phase balance, power factor correction, and production cycle variations.

The Right Solution, The First Time.

Why Teams Choose Our Load Studies

We’ve conducted hundreds of load studies across Phoenix, from small commercial buildings to large industrial complexes. Our reports deliver actionable insights, not just raw data. Every study includes demand curves, power factor analysis, compliance documentation, and clear recommendations formatted for engineers, insurance carriers, and permit officials.

A Phoenix distribution center needed to add refrigeration equipment but their insurance carrier required load documentation before approval. Our 30-day study showed peak demand at 520A on their 800A service, adequate capacity with proper margin. The facility avoided a $60,000 service upgrade and satisfied insurance requirements with our NFPA 70B-compliant report.

Our studies meet NEC Article 220 and NFPA 70B standards. When upgrades are needed, like panel replacements or commercial electrical work, we handle everything and document it properly.

Frequently Asked Questions

FAQs: Electrical Load Studies & Power Monitoring (Phoenix Metro)

How long does a load study take?

30-day load studies require one month of monitoring plus report preparation. Plan for 5-6 weeks total from installation to final report delivery.

Can a load study stop nuisance breaker trips?

Yes. Load profiles and power quality data reveal overloads, imbalances, and harmonics so we can correct the root cause.

Will I get a report for insurance/compliance?

Yes. Your report includes charts, findings, and NFPA 70B/NEC references when applicable.

Can you make the fixes if something fails?

Yes. Our licensed electricians handle all recommended work, including panel upgrades, service replacements, and power quality improvements. We provide detailed proposals for any needed repairs.

Do you provide continuous facility power monitoring?
Absolutely – ideal for critical sites and expansions. We can set alerts and seasonal reporting.
Should we add infrared thermography?

It’s a great companion to a load study. Thermal imaging validates hot spots and loose connections before they escalate.
