When selecting your cable you need to make sure that:
- It has a sufficient current rating for the expected load in the circuit, including a margin of safety.
- The intended cable run length will not cause a voltage drop of more than about 3%
- The material properties are appropriate for the application
Get these right and you can be confident that your cable is right for the job!
