*The current ratings above are an indication only and will not apply in all
circumstances.
The actual maximum current rating is determined by the maximum allowed
temperature for the wire (150 °C).
The temperature of the wire is affected by many factors including the
temperature of adjacent wires, how the wires are bundled and covered, the
ambient temperature and the current.
