Overview
EN 50374:2025/A1:2025 - Conductor cars (CLC/CENELEC) is a European amendment standard that defines requirements for conductor cars used to access overhead line conductors, shield wires, or shield wires with integrated communication systems for live working tasks such as rectifying defects and installing components. The scope explicitly includes bicycle-type access equipment where applicable. The amendment (A1) updates the 2025 version and includes a revised Annex ZZ mapping the standard to the essential requirements of Directive 2006/42/EC (machinery).
Key administrative dates:
- Latest national implementation (dop): 2026-10-31
- Latest withdrawal of conflicting national standards (dow): 2028-04-30
Key topics and requirements
This standard focuses on safe design, use and conformity of conductor cars for live working and overhead line access. Major technical topics covered (by clause references in the standard) include:
- Electrical safety and protection against electric shock (live working considerations)
- Mechanical and structural requirements for access equipment and carrier platforms
- Insulation, clearances and electrical creepage distances relevant to live-line operations
- Operational controls, stability and load handling for safe access to overhead conductors
- Inspection, testing, maintenance and documentation requirements to ensure ongoing safety and compliance
- Marking, user instructions and conformity information tied to machine-safety obligations
- Relationship to the Machinery Directive - Annex ZZ provides a direct mapping of standard clauses to the essential health and safety requirements of 2006/42/EC.
Note: the standard’s clause references (for example clauses in sections 5, 6 and 7) provide the detailed normative requirements; this summary does not reproduce technical specifics.
Applications and who uses it
EN 50374:2025/A1:2025 is intended for:
- Transmission and distribution utilities conducting live-line maintenance
- Manufacturers and designers of conductor cars and bicycle-type access equipment
- Contractors and field crews performing overhead line repairs, fittings installation and defect rectification
- Safety engineers, certifiers and notified bodies assessing machinery conformity with EU rules
- National standardization committees implementing the CENELEC standard nationally
Practical applications include live-line fault repair, installation of line fittings, routine inspection and any elevated access tasks on power transmission and distribution lines where conductor cars are used.
