Form 2b External cabling terminals are separated from the busbar. As illustrated in the above general arrangement, in form 3bih construction the separation between functional units and busbars and busbars and terminals for external conductors is achieved by the use of insulation of busbars and housings of circuit breakers. Form 3Bih will not be accepted. You might have to edit items in a switchboard for several reasons such as, to change a command label or change how a command performs. The distribution switchboard enclosure provides dual protection: Protection of switchgear, indicating instruments, relays, fusegear, etc. The main difference is the voltage that they are designed to handle. Form 3b combines the advantages of form 3a and form 2b, separating the output terminals and the busbars. We specialise in the manufacture of: Form 1, Form 2, Form 3, Form 3Bih and Form 4 segregation standards Mechanical Switchboards up to 6500Amp capacity I also agree that your example of 3bih cannot be regarded as safe due to exposed connection terminals which could be live.
