I am currently training to become a inspector for electrical
installations. While studying the Installation certificate I came
across the section 'Main Switch or Circuit Breaker', where it asks for
the type of main switch. Now, modern type circuit breakers don't seem
to be a problem since the desired data is written on the main switch
(usually BS-EN 60947-3). My problem, what needs to be filled into the
box if the installation has old type BS 3036 rewirable fuses. It does
neither say on the board nor the main switch and nobody I know seems to
be able to tell me. Do any of you inspectors out there know? Also,
where can I find the current rating? Thanks brothers (and sisters).

Can't your training provider answer the question? Older consumer units
were made to BS 5486 Part 13 and I expect that would cover the main
switch, which of course is an integral part of the unit.
