Calculators & Tables FAQs
| Q | What size cables do I need to use in my electrical installation? |
| A | The size of the cable is determined by the amount of current going through the cable and the cable's run length. The easiest way to work the cable size out is by using our Voltage Drop Calculator. |
| Q | What size heat shrink sleeving will fit my cable? |
| A | We have made a chart showing which size heat shrink sleeving can be used for each cable size. |
| Q | What size fuse do I need to use? |
| A | The fuse needs to be rated above the current that is going through the cable and below the cable's overall rating. For example, if you had a 5A load going through 21A cable, you could use a fuse between 7.5-15A. |
