4 core cable carries the three phases and a full-size neutral: the standard choice for three-phase supplies with neutral, distribution boards, and feeders to buildings and machines.
What the cores are
Three phase conductors (R, Y, B) and a neutral of the same size. Earth is run as a separate conductor or through the armour, as your electrician specifies.
