What's special about Electrical maintenance in healthcare environments?
Electrical maintenance in healthcare environments is unlike any other setting. Patient care areas are mission-critical—any electrical failure could jeopardize lives and disrupt essential medical services. Healthcare equipment relies on consistent, properly maintained power sources to operate safely and accurately, avoiding performance drops or false alarms. Regulatory agencies such as the Joint Commission and AAAHC mandate strict standards for electrical reliability and documentation as part of their Environment of Care guidelines. That’s why preventive maintenance isn’t just recommended—it’s essential. Our team performs all work with minimal disruption, ensuring critical facilities remains fully operational while we maintain the systems that matter most.

Line Isolation Monitor (LIM) Panel Testing
LIM panels monitor isolated power systems—commonly used in operating rooms—to detect ground faults and alert facility staff.
How We Test:
- Inspect visual and audible alarm functions
- Simulate fault conditions to validate monitor accuracy
- Test per NFPA 99: Monthly for analog systems, annually for self-testing digital systems
Benefits:
- Prevents electrical shock risks in surgical suites and ICUs
- Ensures NFPA 99 compliance
- Protects sensitive equipment and vulnerable patients
Critical Receptacle Testing
Receptacles in patient care areas must be inspected and tested regularly to confirm that they’re safe and operational.
How We Test:
- Inspect visual and audible alarm functions
- Simulate fault conditions to validate monitor accuracy
- Test per NFPA 99: Monthly for analog systems, annually for self-testing digital systems.
Benefits:
- Prevents electrical shock risks in surgical suites and ICUs
- Ensures NFPA 99 compliance
- Protects sensitive equipment and vulnerable patients
Custom plans for Joint Commission Environment of Care or AAAHC Compliance
Accreditation surveys require documented, proactive electrical maintenance. We help you meet those requirements with ease.
What’s Included:
- On-site assessment of your current maintenance program
- Customized inspection and testing schedules
- Staff training for documentation and reporting
- Support during audit preparation
Benefits:

Critical Receptacle Testing
Receptacles in patient care areas must be inspected and tested regularly to confirm that they’re safe and operational.
How We Test:
- Perform visual inspections for damage or wear
- Verify correct polarity and grounding
- Measure grounding blade retention force (115g minimum per NFPA 99)
- Annual testing for non-hospital grade outlets in patient rooms
Benefits:
- Prevents equipment malfunction or electrical shock
- Enhances code compliance and patient area safety
- Identifies worn or damaged receptacles before failure
