Copper and aluminium cable cross-section calculation

1) Allowable % value for voltage drop:

1,0 % - together on the connecting wire and the input main wire - (before electricity meter)

1,0 % - together on the ascendant and branching main wire - (before electricity meter)

1,5 % - ordinary and lighting network - (after electricity meter)

3,0 % - motoric network - (after electricity meter)

2) Please choose the typ of the electric network:

3x400/230V - (5 conductor (3P+N+PE) 3 phase asymmetric)

3x400V - (4 conductor (3P+PE) 3 phase asymmetric (f.ex.:motoric))

1x400V - (3 conductor (2P+PE) 3 phase asymmetric)

1x230V - (3 conductor (L+N+PE) 1 phase)
