    Grounding Electrode Conductors in Multicore Cables

    A marina floating dock with a large 1-phase transformer is being fed from shore two multiconductor cables each of which incorporates 4-#1 bare ground conductors (83,690CM each). The transformer secondary neutral must connect to an electrode grounding wire that in this case must be sized as the...

    Generator Neutral Grounding

    An odd arrangement of five generators; 2-3500 kW gas turbines, 2-800 kVA gas engines and 1-800 kVA diesel unit, all rated at 11 kV and different rotational speeds. What is the best way to handle the neutral grounding of these different units? 1) Use a medium voltage switch or circuit breaker...
