Audit Timeline and Process
Initial Consultation (30-60 minutes)
Review building history, discuss concerns, identify specific areas of focus, and establish audit scope and objectives.
Visual Inspection (2-4 hours)
Comprehensive walkthrough examining panels, wiring, outlets, switches, lighting, and equipment connections throughout the facility.
Testing & Measurements (1-3 hours)
Voltage testing, load analysis, thermal imaging scans, ground resistance testing, and GFCI/AFCI function verification.
Report Preparation (2-3 business days)
Detailed written report with findings, photos, code violations, safety concerns, and prioritized recommendations with cost estimates.
Typical Audit Duration
Small Office (under 5,000 sq ft): 3-5 hours on-site
Medium Commercial (5,000-20,000 sq ft): 6-10 hours on-site
Large Facility (20,000+ sq ft): 1-3 days on-site
Complex facilities with specialized equipment, multiple buildings, or extensive electrical systems may require additional time.
Common Findings Requiring Immediate Attention
Critical Safety Hazards
- • Overheated connections detected by thermal imaging (fire risk)
- • Missing or damaged panel covers exposing live electrical parts
- • Improper grounding creating shock hazards
- • Overloaded circuits exceeding rated capacity
- • Water intrusion in electrical equipment
Code Violations
- Missing GFCI protection in bathrooms, kitchens, or outdoor areas
- Inadequate emergency lighting or exit sign illumination
- Improper wire sizing for equipment loads
- Inaccessible electrical panels or disconnect switches
Efficiency Opportunities
- Outdated lighting systems (LED upgrade potential)
- Power factor correction opportunities
- Occupancy sensor and automation upgrades
- Voltage optimization systems
Montana-Specific Considerations
Montana's unique climate and building characteristics require special attention during commercial electrical audits:
- Heating Load Analysis: Montana winters demand significant electrical heating capacity. Audits verify your system can handle peak winter loads without overloading circuits.
- Backup Power Readiness: Rural Montana businesses face longer power outage durations. Audits assess generator integration and automatic transfer switch functionality.
- Outdoor Equipment Protection: Extreme temperature swings require proper weatherproofing of outdoor electrical equipment and conduit systems.
- Older Building Upgrades: Many Montana commercial buildings predate modern electrical codes. Audits identify necessary upgrades for safety and compliance.
What You'll Receive
Comprehensive Audit Report Includes:
- Executive Summary: High-level overview of findings and critical action items
- Detailed Findings: Room-by-room documentation with photos and thermal images
- Code Compliance Assessment: Specific NEC and Montana code violations identified

Preparing for Your Audit
To maximize the value of your commercial electrical audit, prepare these items in advance:
- Building electrical plans and as-built drawings (if available)
- Previous inspection reports or electrical work permits
- List of known electrical issues or concerns
- Access to all electrical rooms, panels, and equipment
- Recent utility bills showing energy consumption patterns
Clear access to electrical equipment and advance notice of any areas requiring special attention helps ensure a thorough, efficient audit process.
