Electrical Special Inspection

What we inspect

We inspect electrical installations against the California Electrical Code and the approved plans, at rough-in and at final.

• Service equipment, panelboards and switchboard installation, mounting and working clearances
• Conductor type, size, insulation rating and ampacity for the application and ambient conditions
• Overcurrent protection sizing and coordination with the approved plans
• Raceway type, fill, support spacing, expansion fittings and securement
• Box fill, support and accessibility
• Grounding electrode system, conductor sizing and connection method
• Bonding of metallic systems, including water piping, gas piping and structural steel
• Equipment grounding conductor continuity
• Arc fault and ground fault protection where required
• Penetration protection where raceways pass through rated assemblies
• Labeling, circuit directories and available fault current marking

Working clearances

Required working space in front of electrical equipment is one of the most frequent late-stage conflicts on a project, because other trades fill it after the electrician is done. We check clearance at rough-in and again at final, since the condition at final is the one that matters.

Common questions

Do you inspect solar and battery storage installations?

Contact us with the project scope. We handle conventional commercial and residential electrical inspection; specialty PV and energy storage work is scoped case by case so we do not take on something outside our qualifications.
