Electrical Inspections and Maintenance.
Find the Problem Before It Finds You.

NFPA 70B is the national standard for electrical preventive maintenance. The 2023 edition converted it from a recommended practice into a formal consensus standard with mandatory shall requirements for electrical maintenance programs — defining how facilities must design, implement, and document an Electrical Maintenance Program. Where adopted by your authority having jurisdiction, referenced in your insurance requirements, or specified in contracts, its maintenance intervals and procedures become enforceable requirements. OSHA can also reference NFPA 70B as the benchmark for proper maintenance when evaluating electrical hazards under the General Duty Clause. NFPA 70B applies to industrial plants, commercial buildings, and large residential complexes — any facility with significant electrical infrastructure that wants to reduce fire risk, unplanned downtime, and regulatory exposure. Cali Rollin Electric structures all preventive maintenance work to align with NFPA 70B expectations.

A proper electrical preventive maintenance visit goes far beyond a quick look. A typical commercial PM visit includes infrared thermography to find hot spots caused by loose connections, overloads, or failing breakers — performed with equipment energized and under load. Visual inspection of panels, switchgear, transformers, disconnects, and accessible wiring for overheating, corrosion, contamination, damaged insulation, and labeling issues. Mechanical and electrical checks including torque-checking accessible lugs and terminations, verifying breaker operation, testing GFCI devices, cleaning out dust and debris, and confirming proper grounding and bonding. Functional testing of critical systems including transfer switches, emergency and egress lighting, and other life-safety circuits. A written condition assessment rating major equipment for physical condition, criticality, and operating environment to set risk-based maintenance intervals. Cali Rollin Electric tailors the PM scope to your specific facility while following NFPA 70B structure throughout.

Yes. NFPA 70B requires documented, auditable maintenance records as part of a formal Electrical Maintenance Program — not just informal notes. After a preventive maintenance visit you receive a written report listing all equipment inspected, infrared images of any anomalies with temperature data and severity ranking, noted code issues or safety concerns, recommended corrective actions prioritized by risk and criticality, and updated equipment condition ratings with suggested maintenance intervals. This documentation is what your insurer, safety team, and auditors expect to see if there is ever an incident or claim related to the electrical system. Cali Rollin Electric delivers the written report the same day or within one business day of the inspection.

Under the 2023 NFPA 70B standard, all electrical equipment must receive at least an annual preventive maintenance inspection that includes infrared thermography. Equipment in poor condition or in harsh environments — classified as Condition 3 under NFPA 70B — requires inspections every six months. Detailed maintenance tasks including cleaning, mechanical checks, and electrical testing on panelboards and switchboards have a base interval of approximately five years, adjusted shorter based on condition and criticality. System studies covering short-circuit analysis, coordination, and arc flash must be reviewed and updated at least every five years or sooner if the system changes. For most commercial facilities in Santa Clara County a practical schedule is annual IR and visual PM on all major electrical gear, with deeper cleaning and testing every three to five years and more frequent visits for critical sites like data rooms, healthcare facilities, or industrial production lines.
