What is meant by 3.5 core cable?
3.5-Core Cables A 3-phase system may have a neutral wire. This wire allows the 3-phase system to be used at higher voltages while it will still support lower voltage single phase loads. It is not likely in such cases that the loads will be identical, so the neutral will carry the out-of-balance current of the system.
