My situation is that the transformers are located in a vault right next to the service room. There is no real impedance between the trans formers and the main circuit breaker. There is not really room in the service room to add disconnects ahead of the switchgear and I can not put the main disconnect in the transformer vault.
Can anything be put between the transformers and the main disconnects on the service entrance (e.g. fuses)?
(This is 208V)
