Customize Your Electrical Safety: PESDs Built for Your Panel
When it comes to electrical safety, one size rarely fits all. That's why Grace offers Permanent Electrical Safety Devices (PESDs) tailored precisely to your unique operational needs—ensuring unmatched safety, compliance, and productivity.
Why Choose PESDs?
PESDs improve electrical safety by allowing voltage presence verification and absence of voltage testing without exposing personnel to hazardous voltage. They significantly enhance compliance with NFPA 70E and OSHA standards, reduce downtime during Lockout/Tagout (LOTO) procedures, and provide a safer, more productive working environment for your maintenance teams.
Mechanical vs. Electrical LOTO
According to the Electrical Safety Foundation International (ESFI), there were 3,260 non-fatal electrical injuries involving days away from work in 2021 and 2022 combined. A 2024 study by Johns Hopkins University estimates approximately 630 arc flash injuries occur annually—many of which happen during mechanical and electrical LOTO procedures and are preventable with PESDs and improved safety procedures.
- Mechanical LOTO involves isolating mechanical energy sources like hydraulic, pneumatic, or kinetic energy to prevent accidental equipment activation. PESDs use LEDs to clearly indicate voltage presence, ensuring mechanical maintenance tasks don't inadvertently expose workers to electrical hazards.
- Electrical LOTO specifically targets electrical energy isolation. Without PESDs, traditional voltage verification requires opening energized panels, risking arc flash incidents, electric shock, and significant downtime.
When to Use PESDs (and the Risks if You Don’t)
Use PESDs during routine maintenance, troubleshooting, or tasks requiring LOTO procedures. Failing to incorporate PESDs can lead to:
- Increased Arc Flash Incidents: Each unnecessary panel opening risks severe injury or fatality from arc flash incidents.
- Extended Downtime: Without PESDs, verifying voltage absence can extend procedures by 30–45 minutes, significantly impacting productivity.
- Reduced Equipment Life: Frequent panel openings invite contaminants, reducing electronic component life by up to 50% according to NEMA, increasing maintenance frequency and repair costs.
Customized PESD Solutions: The Right Device for Every Application

- Flex-Mount Voltage Indicators
- Designed for directional LED visibility from any side of electrical equipment using M20 or 3/4” conduit knockouts.
- Includes labels for top, bottom, left, or right orientation.
- Fully potted and rated for CAT III & IV, IP67, and suitable for AC (20–600 VAC) and DC (20–1000 VDC) applications—including 5-wire wye systems.
- Ideal for motor disconnects, load centers, pump facilities, UPS systems, and solar arrays.
- Medium Voltage Indicator
- Designed to mount directly to standard DIN rails, these compact indicators offer internal voltage presence confirmation without requiring external access—ideal for OEMs and compact enclosures.
- Designed to mount directly to standard DIN rails, these compact indicators offer internal voltage presence confirmation without requiring external access—ideal for OEMs and compact enclosures.
- Test Point PESDs
- Multimeter-compatible test points allow qualified personnel to perform absence-of-voltage testing safely and accurately using a standard voltmeter.
- Essential for NFPA 70E Article 120.6 compliance, test point PESDs support applications up to 1000V AC/DC and cuts LOTO times by up to 45 minutes, directly improving productivity.
- Combination PESDs (ChekVolt®)
- Combine multimeter-compatible test points and LED voltage indicators into a single compact device, delivering both voltage presence indication and safe absence-of-voltage testing in one panel-mounted solution.
- ChekVolt AC3, DC2, DC3 Models:
- AC3: Optimized for 3-phase AC systems up to 1000V.
- DC2: Tailored for 2-wire DC systems (e.g., solar or EV applications).
- DC3: Supports 3-wire DC systems with separate ground/neutral configurations.
- 3kV Test Point and Indicator PESDs
- Designed for high-voltage equipment, these 3kV test points incorporate patented 10:1 voltage divider technology.
- Multimeter-compatible and ideal for 3-phase systems and large industrial machinery, enabling safe absence-of-voltage testing on systems up to 3kV.
- Door-Mounted Kits (Low-Profile Options)
- Mount voltage indicators such as the R-3W series or ChekVolts directly to the panel door for flush-mount operation.
- Ideal for installations where low-profile components may be required
- Custom Labeling
- Include custom-written safety messages and hazard warnings directly on the PESD faceplate to support your internal safety protocols.
