The EASA Part 66 B2 AML coverage (to date) allows holders
to make certification on ATA Chapter 24 distribution systems,
this would include G.C.U.s, B.C.U.s, Contactors, relays,switches etc
BUT NOT specific system components that 'interface' directly with a
mechanical system eg: Engine A.C. Generator...
Below is the link to the CAA guidance document for the B2.

Other systems, such as ATA Chapters 21,26,28,30 are almost
no-go areas for today's B2 because of this 'mechanical interface'
Issue. Industry is more than aware of this underutilisation of B2s.
However, in reality, in the UK as of today, the B2 will invariably still be actually carrying out the B1s 'electrical system' work, certainly WRT anything to do with wiring - AND definetly if it involves troubleshooting
or more advanced fault isolation techniques/equipment.
There are plans by EASA to address this issue in the form of
a NPA (see Page 6 of 116 below). When it will actually be implemented
across all NAAs, I'm unsure. Maybe Mr Banal or Mr Nicholas will tell you?
