An electrical inspection is a specialized assessment of a building's electrical infrastructure, evaluating capacity, condition, and code compliance of panels, wiring, and service equipment. Beyond simply confirming stated electrical capacity, a thorough inspection verifies the infrastructure can actually deliver that capacity reliably, since aging equipment can underperform its rated specifications.
What a thorough electrical inspection covers
| Component | What's assessed |
|---|---|
| Main service and panels | Condition, capacity, code compliance |
| Wiring | Age, condition, capacity for intended loads |
| Grounding and safety systems | Proper grounding, circuit protection |
| Specialized equipment | Three-phase service, backup power systems |
What to watch for before committing
Verified vs stated capacity
Confirm the inspection verifies actual deliverable capacity, not just stated or nameplate capacity, since aging equipment can underperform specifications.
Load calculation against your equipment needs
Have your specific equipment load calculated and compared against verified available capacity, not just general estimates.
Code compliance for current standards
Verify the electrical system meets current code requirements, since older systems may have compliance gaps requiring correction.
Qualified electrician engagement
Engage a licensed electrician with commercial or industrial experience, not a general property inspector, for this specialized assessment.
Upgrade cost estimates if needed
If capacity or condition issues are identified, get realistic upgrade cost estimates from both the utility and an electrical contractor.
Panel age and replacement risk
Assess panel and major component age relative to typical service life to understand near-term replacement risk.
When you need to know this
- Equipment-intensive operations — verifying actual deliverable capacity matches your specific equipment needs
- Purchasing or leasing an older building — assessing electrical infrastructure condition and compliance
- Planning automation or heavy equipment installation — confirming capacity supports your specific power requirements
- Budgeting for potential capacity upgrades — understanding current condition and realistic upgrade costs if needed
