Does anyone know the BS type numbers for this board?  I took a number but misplaced the other BS 5486 relates to the CU but not sure what BS the fuses are.

    As BOD has already pointed out those fuses are BS 3871 Type 2 circuit breakers. They are Crabtree C50 circuit breakers, the ones with white paint in the handles are 3kA rated and the ones with yellow paint are 4.5kA rated. The main switch will be BS 5419 if it is original?


    Built like the proverbial brick outhouse but watch out for the exposed live bus bars inside.




    I know of a small chapel that has a Crabtree three phase C50 board. There are six overhead 3kW infra red heaters, each switched by a C50 M.C.B. There are no local functional switches. The C50 M.C.B.s are still working well after many years used as functional switches.
