Electrical Safety for Medical Equipment
Leakage, earth, applied parts and testing after repair
Every repaired device goes back to a patient. Electrical safety testing is the last line between your repair and that patient — and it is also the test most often done as a formality. This course explains why the limits exist, how the analyzer measures, and how to test and document properly after repair and at every PM.
Ten microamps you cannot feel can stop a heart on a catheter.
- Electrical safety testing is required after repair and periodically, but many engineers press 'auto' without knowing what the analyzer measures.
- A failing result is often 'fixed' by changing the test method instead of finding the fault.
- Auditors and tenders ask for documented tests; a printout with no understanding behind it does not protect anyone.
After the course you can
Curriculum
Explain what makes electric current dangerous, tell macroshock from microshock, and understand why a current too small to feel can kill a patient with a conductive path to the heart - so that every limit in the rest of the course makes sense.free
20 min02Protection classes (I, II, internally powered) and applied part types (B, BF, CF)
Read the classification of any medical device from its label and manual - protection class and the type of each applied part - and know which tests and limits that classification brings, and which repairs can silently change it.20 min03Leakage currents, protective earth resistance and insulation
Know what protective earth resistance, insulation resistance and each leakage current actually measure, which limits apply in design and in service, and how to read a result instead of just accepting 'pass'.22 min04Testing after repair and periodic testing: how the analyzer works and the test sequence
Run a correct IEC 62353 test sequence after a repair or at a PM, choose between the direct, differential and alternative leakage methods for a given device, and know what the analyzer is actually doing at each step.22 min05Defibrillation-proof applied parts and what they mean for service
Recognise defibrillation-proof applied parts, understand which parts of the device and its cables provide the protection, and avoid the repairs and substitutions that silently remove it.20 min06Recording the tests, pass or fail, and what to do with a failing device
Write an electrical safety test record that another engineer or an auditor can trust and repeat, make a defensible pass/fail decision including trends, and handle a failing device so that it cannot reach a patient by mistake.20 min—Exam

Written by a service engineer working with medical equipment since 2014, including 6.5 years at GE Healthcare and service supervision at Mindray, together with the engineers of Service Engineer.
FAQ
Does this replace the standard?
No. It explains how to apply IEC 62353 and the manufacturer's instructions in practice. Always use the current edition of the standard and local rules.
Do I need an analyzer to take the course?
No, but you will need one to apply it. The course explains how analyzers work regardless of brand.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
