The code is very vague on where disconnecting means are actually required. It usually depends on what loads are supplied from the feeder.

For example, if the feeder supplied a group of motor branch circuits, the feeder overcurrent protection would be as required in 28-204, and it would be impractical to install the reqired overcurrent protection withouut a disconnecting means.

Good engineering practice would dictate that one disconnecting means, and overcurrent protection, is installed for the feeder to the splitter, located at the supply end of the feeder.

Each tap (branch circuit or sub-feeder) supplied from the splitter requires a disconnecting means, and overcurrent protection, located where it receives it's supply from the splitter.

The general reqirement for, and location of, overcurrent protection is covered in Rule 14-100.
