Unfused busbar tap-offs

Apostolos
Good afternoon.

I have a hotel where the consumer units of each room are fed through a 63A horizontal busbar using tap-offs along the way.

In the past the norm was to used 32A fused tap offs for each CU. The cable to each CU was rated at 32A as expected.

Could these tap-offs be unfused and the cables feeding the consumer units be rated at 63A ....same as the busbar?

Is this contrary to any regulation?

Thank you

    Un fuse Bus bar tap offs can fix but should have a fuse or Mcb next to each tap offs


    When this Bus bar system Design 1st step is must workout the total reqired  current capacity of the relevant building after that you must identify the required current  capacity  for each consumer in according that you can suggest the fuse or Mcb current capacity  ***  ,be care full to select the Mcb rang not exceed over than 5% of actual current required to the consumer
