· Dimensioning full of low voltage circuits with the most frequent set up methods

· Phase cable dimension, neutral, protective conductor

· Criteria based on the admissible present of the cable, voltage drop and overcurrent protection

· Designation of the most used cables.

· Circuits with computerized circuit breaker until In = 4000 A (Ir rating setting), most fuse In = 1600 A (gG type), most 12 conductors parallel per phase, maximum size 630 mm²

· Short-circuits, including MV network, LV lines and final circuit

· Estimate of the utmost short-circuit current (simplified method)

· Maximum protected size for minimum quick circuit (approximate method)

Parameter settings for calculations:

· Constants (voltages, conductivity, temperatures, etc.) that have an result on electrical calculations

· Protections (circuit breakers and fuses)

· Selection of minimal price for circuit-breakers with regulation and maximum cable measurement for multi-conductor grouping per phase

· Method estimation of the reactance

· Conductivity of the conductor relying on the present of the circuit (constant, in accordance with the anticipated present, most cable temperature)

· Use reduction elements by grouping cables/circuits

· Use of things of diversity/utilization

· Reference paperwork: IEC Standards, REBT (sp), Technical Application Guide, (UE) 2016/364
