what does it mean by 4 core cable, 35 mm. can it be used for DC and AC as well. can it be used for a 3 phase AC. what are its advantages and disadvantages? is one core means one phase? can we use 2 core cable for 3 phase AC? am really confused please explain.
A 4 core cable has 4 conductors in an overall sheath. The 35 mm indicates the area of each conductor's copper is 35 square mm. You can use the 4 core cable for 3-phase power (3 wires with a spare or ground). You cant use a 2-core cable for three phase service, unless you are using three 2-core cables with the 2 wires connected in parallel to provide one of the phases. It can be used for AC or DC. TexMav
