    Note: These values apply to the majority of cases. further information should be sought in unusual cases eg.:

    When high ambient temperatures are involved, ie. above 30°C

    Where long lengths are used

    Where ventilation is restricted

    Where the cords are used for other purposes, ego internal wiring of apparatus.
