| 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. |
