Consider that I am installing an external switch between a pad mounted transformer and a switchboard so that I can split power to the switchboard and MDP I plan to install.
I now have a new circuit that is feeding the external transformer with additional ampacity; that being the newly installed MDP and its circuit which now feed the external transformer.
I would much rather protect the building connected to the switchboad than the external transformer. Should I increase the size of the fuse on the primary side of the transformer or install a new circuit breaker and fuse on the switchboard in order to better protect the building connected to the switchboard?
The newly installed MDP is not connected to the switchboard but is located inside the building.
