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

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

(ii) Where long lengths are used

(iii) Where ventilation is restricted

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