Note: 1. Wire sizes were selected for three cables per bundle at 40 °C ambient temperature with the
rated current.
2. Use cable with a minimum withstand voltage of 600 V for main circuits.
3. If cables are bundled in PVC or metal ducts, consider the reduction ratio of the allowable
current.
4. Use heat-resistant cable under high ambient or panel temperatures where normal vinyl
cable will rapidly deteriorate.
The following table shows types of cables and must be used in conjunction with Table7.6
and Table7.7.
Note: 1. Use cable with a minimum withstand voltage of 600 V for main
circuits.
2. If cables are bundled in PVC or metal ducts, consider the reduction
ratio of the allowable current.
3. Use heat-resistant cable under high ambient or panel temperatures
where normal vinyl cable will rapidly deteriorate.
