Overview

EN IEC 60335-2-76:2021/A11:2021 is a CENELEC amendment to the safety standard for household and similar electrical appliances - particular requirements for electric fence energizers. It applies to electric fence energizers with a rated voltage not exceeding 250 V. Amendment A11 updates definitions, construction and test requirements, marking and instructions, and adds a new normative annex for time delayed electric fence energizers. This European amendment is intended for manufacturers, test laboratories, conformity assessors and technical regulators involved in electric fence energizer safety and compliance.

Key topics and technical requirements

• Scope and status

  • Amendment to EN IEC 60335-2-76:2021; approved by CENELEC (Sept 2021).
  • Not linked to specific European legislation but specified as CENELEC national standard.

• Standard load definition

  • Standard load comprises a non‑inductive resistor R1 (50 Ω–500 Ω) giving the most severe condition, plus a non‑inductive variable resistor R2 arranged to maximize energy per impulse or cumulative peak current >20 A.

• Output limits and pulse characteristics

  • For typical energizers:
    • Energy per impulse (in R1) shall not exceed 5 J.
    • Peak current in R1 shall not exceed 20 A for more than 200 µs cumulated per impulse.
    • Impulse repetition rate shall not exceed 1 Hz.
    • Impulse duration shall not exceed 10 ms.
  • Functional/routine test: output checked with 500 Ω load; must meet the above limits.

• Time delayed energizers (Annex ZAA)

  • Defined terms: time delayed energizer, delay time (15–60 s) and adaptation time (<1 min).
  • Allows higher output energy after delay time under controlled steady‑state limits; Table ZAA.1 sets maximum steady‑state impulse energy vs. load (e.g., ≤100 Ω → 15 J; 500 Ω → 5 J).
  • Alarm and control functions required if maximum output exceeds 5 J under test conditions:
    • Visual and audible alarm (audible ≥55 dB at 1 m).
    • Alarm triggers on sustained drop below 400 Ω and reduces repetition rate (<0.34 Hz); provisions if alarm disabled or external alarm disconnected.

• Marking and instructions

  • Energizers must be marked; time delayed devices require explicit marking or symbol and user instructions (e.g., delay time statement).
  • PVC-sheathed cord: installation instructions must state unit be sheltered and not handled below +5 °C.

Applications and users

• Who uses this standard:
  • Manufacturers of electric fence energizers (design and production).
  • Test laboratories and conformity assessment bodies performing safety and routine tests.
  • Regulatory and procurement teams, installers and farm/equine/livestock equipment specifiers.
• Practical applications:
  • Product design validation, safety certification, type and routine testing, labelling and user instruction development, and compliance checks for energizers used in livestock buildings, security perimeters and agricultural fencing.

Related standards

• EN IEC 60335-1 (Part 1 general requirements)
• IEC/EN references cited (e.g., IEC 60068-2-52, EN 61672 series)
• Other Part 2 standards in bibliography: EN 60335-2-86, EN 60335-2-87
