Em circuitos trifásicos, os condutores de fase, neutro e proteção devem acompanhar o mesmo percurso e permanecer próximos entre si. A ABNT NBR 5410, no item 6.2.10.3, estabelece que os condutores de um mesmo circuito, incluindo o condutor de proteção, devem estar nas proximidades imediatas uns dos outros. Separar, por exemplo, duas fases em um eletroduto e a terceira fase e o neutro em outro, principalmente com grande distância entre os eletrodutos, altera a geometria eletromagnética do circui...
