Can a Automatic Transfer Switch be fed by the secondary side of Utility Transformer with no Main Disconnect Switch? Main Over Current Protection is located at the Main Service after the ATS. What Reference Code Section would this apply to?
 
Interesting to read the label inside of most non fused MTS say service entrance rated

only to add if it non-fused, you have to be careful about the interrupt rating...most, if not all, are 10k
 
it would also require OCPD's also if my reading of the code is still up to par?
It is interesting to me that we seem to all talk of, "Install the disconnect here" when we really mean, "Install the service disconnecting means and service overcurrent protection here." I believe we sort of lost the additional phrase when most people started using circuit breakers and they both were included in the same piece of equipment. :smile:
