[Solved] Long-term Load Capacity of Cu 4mm2 Cable: Comparing Wire & Rope Current Resistance

The discussion centers on the long-term load capacity of a 4mm² copper cable, comparing its current resistance to that of a rope. Participants note that the load capacity for a 4mm² 2-core cable is approximately 34A, with variations depending on installation conditions, such as whether the cable is laid in a wall or loose. It is emphasized that the load capacity is influenced more by cooling conditions than by the type of conductor (wire vs. rope). A specific example mentions a 5x4mm² cable laid in a pipe on a wall, with a load capacity of 29A at ambient temperatures between 15 to 30 degrees Celsius. References to tables and PDFs containing relevant data are provided, although some participants express difficulty in finding specific information regarding the comparison between wire and rope conductors.
