1. Wire sizes are selected for three cables per bundle at 40°C surrounding air tempera-
ture with the rated current.
2. Use a wire with a minimum withstand voltage of 600 V for the main circuit.
3. If wires are bundled in PVC or metal ducts, take into account the reduction of the
allowable current.
4. Use a heat-resistant wire under high surrounding air or panel temperatures, where
polyvinyl chloride insulated wires will rapidly deteriorate.
