Default Does a CU on a sub-main need an integral isolator switch?

2) Practical, you need some way to terminate the live of your incoming
sub main on the the live bus bar(s) of the CU. The live bus bar has no
terminals of its own, and relies on those of the main switch to connect
the incoming feed to the bus bar.

Squidging the wire under the busbar in one of the MCB terminals would be really rough wouldn't it...
