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.
