what is the current capacity 3 core 16sq mm swa
If 16mm is the overall diameter of the cable, yes - If that's the diameter of one core, then no.
Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity
Current is about 18 amps per phase. Allowing for power factor and startup, I'd size the wire for 40 amps per phase, which is #5 wire. This wire has a resistance of 0.39 ohm per 1000 ft, which is 0.39 ohms per 305 meter, or 0.09 ohms per 70 meter. At 40 amps, there is a voltage drop on the wire of 40*.09 or 3.6 volts, less than 1% loss, so that is OK. Use 4 conductor #5 copper wire insulated for 480 volts. <<>> A #12 copper conductor will limit the voltage drop to 3% or less when supplying 13 amps for 230 feet on a 415 volt system.
