Cables running internally through vehicles can generally be divided into two voltage categories – low voltage, between 0 and 60 V, and high voltage, which typically means anything above 60 V (and typically running up to 600, 800 or as high as 1500 V in the e-mobility sector). The key reason for this distinction is safety. how to shorten a knitted cardigan
