***> Cable <***
For aluminium, the minimum CSA allowed is 2.5 mm²; Ecodial has calculated a much lower required CSA. In order not to oversize the cable, switch to copper
As per the given inputs, Ecodial was in a situation to select a conductor size less than 2.5 mm². But it has selected a 2.5 mm² as
a conductor size and it has shown the alarm message as given above.
As per the standard IEC 60364-5-52 and $ 524.1 the cross-sectional area of line conductors in A.C. circuits and of live conductors
in D.C. circuits shall be not less than the values given in table 52-5.
NOTE this is for mechanical reasons.
