How to Use This Checklist

  • Start with the audit details: record the inspection date, who prepared it, the location, the identification numbers of every panel and disconnect you inspect, the ground resistance reading in ohms, the specific findings on transformer and high-voltage equipment, your signature, and the start, finish, and real inspection dates.
  • Inspect electrical panels and disconnects. Confirm at least 36 inches (914 mm) of clearance, intact enclosures and breakers, legible circuit labeling, no thermal damage or arcing, sealed knockouts, identified and unaltered disconnects, and dielectric insulating mats compliant with IS:15652-2006 in front of every work position.
  • Inspect wiring and cables. Check that conductors are fastened, protected, and free of mechanical damage; that no exposed conductors, frayed insulation, or deteriorating jackets are present; that flexible cords are industrial duty and not used instead of fixed wiring; that plenum-rated insulation is used in plenum spaces without conduit; and that conduit, trays, and raceways are installed correctly, supported, and clear.
  • Verify grounding and bonding. Confirm machinery, enclosures, and equipment are effectively grounded in line with applicable standards; that equipment grounding conductors are continuous, securely terminated, and free from corrosion or loose connections; that temporary and portable power sources are properly grounded; that connections are periodically inspected; and that electrodes, bonding jumpers, and bus bars are correctly installed with secure, corrosion-resistant connections.
  • Check LOTO compliance. Confirm lockout/tagout is implemented before any electrical maintenance; that locks, tags, and hasps are available, identified, and applied at all isolation points; that authorized employees receive initial and periodic refresher training; that isolation points are permanently marked, visible, and unobstructed; and that no deviations such as bypassed locks or unauthorized re-energization are present.
  • Inspect machinery and equipment. Check that machine electrical connections are terminated inside enclosures with no exposed conductors; that motor control centers are labeled, documented, and consistently maintained; that E-stops are functional, well placed, and unobstructed; that interlocks and monitoring relays work as designed; and that VFDs and enclosures show no thermal stress, contaminant buildup, or impending failure.
  • Inspect temporary and portable power. Confirm ladders used within the limited approach boundary of energized equipment are non-conductive fiberglass; that cords, strips, and temporary equipment are intact; that cord routing avoids traffic corridors, doorways, pinch points, and damage zones; that installations comply with OSHA and NFPA 70E; that GFCI protection is verified; and that generators and temporary distribution panels are in well-ventilated, properly grounded, weather-protected positions.
  • Verify personal protection and training. Confirm electrical work is performed only by documented, appropriately licensed personnel; that personnel inside the arc flash or limited approach boundary wear rated PPE such as insulated gloves, arc-rated clothing, dielectric footwear, and face protection; that affected employees complete documented electrical safety training; that arc flash warning labels are present, legible, and current; and that insulated tools and PPE are available, inspected, and within certification dates. Then rate the overall adequacy and condition of on-site PPE.
  • Check lighting and emergency systems. Confirm work areas, especially around panels and machinery, meet OSHA illumination levels; that exit signage and egress lighting are functional, illuminated, and routinely tested; that egress paths are clear and marked; that UPS systems and backup generators are load-tested on schedule; and that emergency lighting batteries are periodically tested and replaced on the manufacturer's schedule or on failure.
  • Inspect high-voltage equipment. Confirm transformer vaults and high-voltage areas have adequate ventilation and no stored obstructions; that compliant danger signage is displayed per NFPA 70; that high-voltage conductors and cabling are in approved raceways or conduit, supported, and protected; that high-voltage disconnects are accessible and labeled; and that substation perimeters and enclosures are secured with barriers, locks, and access controls.
  • Score each item as Pass, Fail, or N/A, then close out with documented findings, corrective actions, and a review of the completed report.

What electrical safety inspection covers

An electrical safety inspection is a structured walkthrough of your electrical systems, equipment, and work practices to find hazards before they cause shock, arc flash, fire, or unplanned downtime. It looks at the physical condition of panels, wiring, and grounding; at how work is controlled through lockout/tagout; at the machinery and high-voltage equipment in service; and at the people, protection, and emergency systems around them. This checklist is built as an Electrical Safety Inspection Report. It contains 59 items across ten sections: Audit; Electrical Panels & Disconnects; Wiring & Cables; Grounding & Bonding; Lockout/Tagout (LOTO) Compliance; Equipment & Machinery Electrical Safety; Temporary & Portable Power; Personal Protection & Training; Lighting & Emergency Systems; and Transformer & High-Voltage Equipment Safety. Most items are scored on a Pass, Fail, or N/A scale, with recording fields for measured readings, identification numbers, findings, dates, and sign-off.

Why it matters

Electrical hazards rarely announce themselves. Frayed insulation, a missing knockout blank, a loose grounding connection, or a bypassed lock may sit quietly until someone reaches into a panel or a machine restarts unexpectedly. A regular inspection turns those conditions into recorded, actionable findings. Just as importantly, an inspection documents that you checked the things that matter. The checklist asks you to record panel and disconnect identification numbers, a measured ground resistance reading, and specific findings or anomalies that need further evaluation — so the report shows what was examined, what was found, and what still needs attention.

What a good inspection covers

### Access and the physical condition of equipment A good inspection starts with whether you can safely reach and see the equipment. The checklist asks whether panels and disconnect switches maintain a minimum clearance of 36 inches (914 mm); whether enclosures, doors, and breakers are intact with no damage, cracks, or missing hardware; whether each breaker is accurately labeled against its connected load; whether there are signs of thermal damage, discoloration, arcing, or burn marks; whether knockouts are sealed with approved blanks; and whether disconnects are identified, operational, and free of unauthorized modification. It also checks that dielectric insulating mats compliant with IS:15652-2006 are installed in front of all panel work positions. ### Wiring, grounding, and bonding From there, it moves to the conductors themselves and the paths that protect people from them. It covers securely fastened and adequately protected conductors, the absence of exposed conductors and deteriorating cable jackets, industrial-duty flexible cords that are not substituting for fixed wiring, plenum-rated insulation where conduit is not provided, and correctly installed conduit, cable trays, and raceways. On grounding, it checks that machinery, enclosures, and equipment are effectively grounded and bonded in accordance with applicable standards; that equipment grounding conductors are continuous, securely terminated, and free of corrosion or loose connections; that temporary and portable sources are properly grounded; that grounding and bonding connections are periodically inspected; and that electrodes, bonding jumpers, and bus bars are installed with secure, corrosion-resistant connections. You also record a measured ground resistance reading in ohms. ### Controlling energy Lockout/tagout is where procedures meet practice. The checklist asks whether LOTO is strictly implemented before any electrical maintenance or servicing, whether locks, tags, and hasps are readily available and correctly applied at all required isolation points, whether authorized employees receive training on assignment and periodic refresher training, whether isolation points are permanently marked and unobstructed, and whether any deviations — bypassed locks or unauthorized re-energization — are observed. ### Machinery and high-voltage equipment On production equipment, it checks that machine connections are terminated within enclosures with no exposed conductors or loose terminations; that motor control centers are labeled, documented, and consistently maintained; that E-stops are functional, prominently positioned, and unobstructed; that safety interlocks and monitoring relays work as designed; and that VFDs show no thermal stress, contaminant buildup, or impending failure. On the high-voltage side, it covers ventilation and clearance in transformer vaults, compliant danger signage per NFPA 70, conductors and cabling in approved raceways or conduit, accessible and labeled high-voltage disconnects, and secured substation perimeters and enclosures. ### Temporary power, people, and emergency systems Temporary and portable power gets its own attention: non-conductive fiberglass ladders within the limited approach boundary, intact cords and equipment, routing that avoids high-traffic corridors and damage zones, compliance with OSHA and NFPA 70E for current rating, protection, and installation methods, verified GFCI protection, and generators and distribution panels in well-ventilated, grounded, weather-protected positions. For people, the checklist covers documented qualifications and licensing, rated PPE inside the arc flash or limited approach boundary, documented electrical safety training, current arc flash warning labels, and available and in-date insulated tools and PPE. Finally, it checks illumination against OSHA levels, egress lighting and exit signage, clear and marked egress paths, load-tested UPS systems and backup generators, and periodically tested emergency lighting batteries.

How to carry out the inspection

1. **Set up the audit.** Record the inspection date, who prepared it, and the location. As you move through the site, note the identification numbers of every panel and disconnect you inspect. 2. **Work section by section.** Move through panels and disconnects, wiring and cables, grounding and bonding, LOTO, machinery, temporary power, PPE and training, lighting and emergency systems, and finally transformers and high-voltage equipment. Scoring each item Pass, Fail, or N/A keeps the report consistent and easy to review. 3. **Measure and record where asked.** Take the ground resistance reading at the main grounding electrode in ohms, and document any findings or anomalies related to transformer and high-voltage equipment that need further evaluation or corrective action. 4. **Rate the overall picture.** Give a single rating on the adequacy and condition of electrical safety PPE available on-site. 5. **Close out.** Sign the report and record the finish time and the real inspection start and end dates.

Scoring and sign-off

Each inspection item is scored as **Pass**, **Fail**, or **N/A**. Use N/A only where the item genuinely does not apply to the area or equipment being inspected, rather than as a way to skip something you could not confirm. Items that ask for a value or a description — such as the ground resistance reading, panel and disconnect identification numbers, and high-voltage findings — are recorded directly. The report closes with a signature, the finish time, and the real inspection start and end dates, so the completed record shows who inspected what, when, and what they found.

Frequently Asked Questions

The checklist is scored on a Pass, Fail, or N/A scale. Inspection items covering electrical panels, wiring, grounding, LOTO, machinery, temporary power, PPE, lighting, and high-voltage equipment are each rated as Pass, Fail, or N/A.

The checklist references IS:15652-2006 for dielectric insulating mats, and the temporary power and high-voltage sections refer to OSHA, NFPA 70E, and NFPA 70 for requirements covering current rating, protection, installation methods, and signage. It also asks whether machinery, enclosures, and equipment are grounded and bonded in accordance with applicable standards, and whether illumination meets OSHA levels. Where these standards apply, the checklist names them and asks you to verify compliance.

The checklist includes items on clear labeling of circuit breakers, motor control centers, and disconnect switches; arc flash hazard warning labels; documented LOTO training and periodic refresher training; documented electrical safety training covering hazard recognition, safe work practices, and emergency response; and maintenance of electrical PPE within certification dates. Each of these is rated Pass, Fail, or N/A.

The checklist asks for continuous, securely terminated equipment grounding conductors free from corrosion or loose connections; proper installation of grounding electrodes, bonding jumpers, and bus bars; documented periodic inspection of grounding and bonding connections; and a measured ground resistance reading at the main grounding electrode in ohms.

The checklist requires LOTO procedures to be strictly implemented before any electrical maintenance or servicing; appropriate locks, tags, and hasps to be available, identified, and correctly applied at all isolation points; permanent marking of energy isolation points; authorized employees to receive LOTO training on assignment and periodic refresher training; and no bypassed locks or unauthorized re-energization.

Questions that ask for recorded values, such as the measured ground resistance reading and the documentation of findings, anomalies, or observations related to transformer and high-voltage equipment, are open-entry items. The audit section also asks for panel and disconnect identification numbers, and the checklist records the inspection dates, prepared-by information, location, signature, and start and finish times.
