Minimum 0.75 mm² for external copper wiring; 0.2 mm² for internal wiring.
| Change | Practical Impact | |--------|------------------| | | Clarified that Safe Torque Off (STO) does not fulfill isolation requirements. STO can be used for prevention of unexpected startup only under specific conditions. | | Short Circuit Current Rating (SCCR) | New requirements for determining SCCR through design rules, calculation, or testing. | | Protective bonding revision | Clarified what constitutes the bonding circuit and what cannot be used as a protective conductor (e.g., metal ducts, pipes, ladders). | | EMC requirements | Immunity and/or emission tests are now required unless certain conditions are fulfilled. | | Control circuit reorganization | Clarification that STO of PDS can be used as a stop category 0 (emergency stop), confirmed in EN ISO 13850. | | Two informative tables added | Tables cross-reference which clauses correspond to essential requirements of the Machinery and Low Voltage Directives, providing presumption of conformity. |
EN 60204-1, titled "Safety of machinery - Electrical equipment of machines - Part 1: General requirements," is a harmonized European standard. It is identical in technical content to the international standard .
The standard is structured into 18 main clauses, each addressing a critical aspect of machine electrical safety:

Marco leaned over. “What’s that? A spell book?”
This article provides a comprehensive overview of the (specifically the 2018 edition, currently in effect in 2026), its key requirements, and where to locate the official EN 60204-1 PDF for in-depth study. What is EN 60204-1?
EN 60204-1 is the European harmonized standard for "Safety of machinery – Electrical equipment of machines – Part 1: General requirements." It is identical to the international standard IEC 60204-1. The "EN" prefix indicates that it has been adopted by CENELEC (European Committee for Electrotechnical Standardization).
Live parts must be covered by insulation removable only by destruction. Minimum 0
Minimum IP2X or IPXXB for enclosure openings to prevent finger contact.
Conductors and cables must be selected based on their operating conditions (voltage, current, temperature, and environmental factors). Proper cable routing, segregation of power and signal lines to prevent electromagnetic interference (EMI), and clear color-coding are required. Typically, black is used for AC and DC power circuits, red for AC control circuits, and blue for DC control circuits. Testing and Verification
The EN 60204-1 document is comprehensive, covering several distinct areas of machine safety and electrical engineering: 1. Incoming Supply and Disconnecting Devices
Withstanding an applied test voltage to ensure insulation integrity. | | Short Circuit Current Rating (SCCR) |
, which taught him about the "Automatic Disconnection of Supply" (ADS) [5]. He spent days installing new protective bonding circuits to ensure that if a fault ever occurred, the power would cut out faster than a heartbeat [3]. The Command Center
Clause 8 and Annex A provide clear requirements. Ensure all accessible conductive parts are properly bonded using approved protective conductors only.
The factory floor was a symphony of stress. Shipments were late. The plant manager, Mr. Draper, a man who measured success in decibels and deadlines, was pacing behind the safety cage. “Fix it or scrap it,” he growled. “I’m not buying new parts for this dinosaur.”

Based on years of inspecting machinery and electrical panels, safety experts have identified several recurring non-compliances. The Safe Machine Ltd white paper highlights these common errors in detail:
Every incoming supply must have a disconnecting device that can be locked (e.g., padlock) to prevent accidental energization during maintenance. 4. Safety of Control Circuits
