When a cable manufacturer quotes a current capacity for mains cable, would this figure also be suitable for DC current.
For example, 1 sq mm cable is normally quoted as having a current capacity of 15A. Would this cable be able to carry 15A at say 12 V dc?
I would have thought that the cable needs to be de rated for dc.
Further to this, is there a way of calculating volt drop for DC currents.
Are the volt drops similar for ac and dc for a given current?
For a given current, I would have thought that the volt drop for dc would be greater.
Any comments would be appreciated.
