(Main)Aerospace series - Current ratings for electrical cables with conductor EN 2083
General Information
- Abstract
1.1 This standard specifies current rating data for cables produced with conductors as defined in EN 2083.
1.2 Electrical ratings for continuous and short term conditions are tabulated such that the requirements of EN 3197 are satisfied.
1.3 A procedure for establishing cable current ratings is given in Annex B of this specification.
1.4 The basis for determining current of cables has been to employ a 40 °C rise as the electrical contribution to operating temperature. Note is made in this standard that, in practice, the voltage drop requirements of EN 2282 will often dictate lower current densities. Additionally, reference to appropriate aerospace series standards for cable terminations and connectors will show constraints which may dictate cable size.
1.5 It is stressed that the current ratings given in this document relate solely to copper and copper alloy conductors as defined in EN 2083. The values are based upon historical evidence and are subject to the caveat given in 4.1. Accordingly the acceptance of data without verification in any particular case is a matter of discretion by both the aircraft design and certification authorities.

Overview
SIST EN 2853:2006 is a European standard developed by CEN that specifies current ratings for aerospace electrical cables manufactured with conductors defined in EN 2083. This standard addresses the critical need for reliable electrical cable performance in the aerospace industry by providing tabulated current ratings for continuous and short-term conditions, ensuring compliance with EN 3197. It focuses solely on copper and copper alloy conductors and provides methodologies for establishing accurate current ratings.
The standard plays a pivotal role in aircraft electrical system design and certification, guiding engineers in selecting the appropriate cable sizes to maintain safety, reliability, and operational efficiency.
Key Topics
Scope and Applicability
SIST EN 2853:2006 applies to aerospace cables with conductors per EN 2083 and complies with EN 3197 requirements for electrical installation systems in aircraft. It specifies current ratings under continuous and short-term usage conditions for copper and copper alloy conductors.Current Rating Methodology
The ratings are based on a 40 °C temperature rise of the conductor as the electrical contribution to the operating temperature. This approach balances safety and cable lifetime considerations by limiting “hot cables” that may reduce installed life or pose servicing risks.Tabulated Current Ratings
The standard provides detailed tables showing allowable current values for different cable sizes (AWG) under various duty cycles-including 2 seconds, 10 seconds, 1 minute, and continuous operation. These ratings are essential for ensuring cables do not exceed their rated temperature during operation.Voltage Drop Considerations
Voltage drop data for a 10 m cable length at rated current is included to help designers evaluate power losses and ensure compliance with the voltage drop limits outlined in EN 2282.Verification and Testing Procedures
Annex B describes a normative test method for verifying cable current ratings by monitoring conductor temperature rise in controlled conditions. This supports validation for non-standard cable constructions or specific certification requirements.
Applications
Aircraft Electrical System Design
SIST EN 2853:2006 is integral in guiding electrical engineers to select cables that can safely carry required loads without exceeding thermal limits. Its data assists in sizing cables for wiring harnesses in commercial, military, and space aerospace applications.Certification and Compliance
Regulatory authorities and certification bodies rely on this standard to verify that electrical cable current capacities meet aerospace safety and performance requirements. The detailed testing approach allows for objectivity in acceptance of cable ratings.Electrical Protection Coordination
The current ratings inform setting circuit breakers and protective devices, ensuring they operate within safe overload limits without nuisance trips, improving system reliability.Maintenance and Servicing Safety
By controlling conductor temperature rise, the standard reduces the risk of damage to cables and associated components, enhancing the safety of maintenance personnel during inspection and repair.
