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.
