Draft Paper: Overview of IEC 61439-6 for Busbar Trunking Systems 1. Introduction Clause 8
Routine Verification
: Every unit produced must undergo basic checks, including dielectric tests and earth continuity, before being dispatched.
Scope of IEC 61439-6
- Perform a risk assessment considering patient safety, continuity of supply and electromagnetic compatibility with sensitive medical equipment.
- Follow national regulations and healthcare electrical standards (e.g., IEC 60601 family for medical electrical equipment) in addition to IEC 61439‑6.
- Ensure involvement of qualified electrical engineers and medical facility stakeholders during design and commissioning.
Clause 8.3.3 – Temperature change causes expansion. For every 50 meters of straight run, install an expansion unit. The standard provides the formula.
