Question A: Can the main overcurrent protection device (OCPD) of a panel fed by the secondary conductors of a transfomer be considered the secondary protection for the transformer?
Question B: Can a primary fuse that is NOT connected directly to the primary terminals of the transformer (but connected to it through a cable) qualify as primary protection?
Just to clarify my quuestion.
1. I am not asking about conductor protection.
2. I am not asking if the primary or secondary OCPD is properly sized.
3. I am asiking if the fuse in the primary side of the transformer qualifies as a primary OCPD even though it is not cnnected directly to the terminals of the transformer and this fuse is part of a feeder circuit of the upstream panel.
4. I am asking if the main OCPD for the downstream panel conected to the transformer qualifies as a secondary OCPD for the transformer even though it is not connected directly to the secondary terminals of the transformer but there is a cable between the transformer secondary and the main OCPD for the downstram panel.
Thanks.
