: Pin-type (universal pole structure) and Fork-type (U-shaped for screw terminals).

When connecting several breakers to a single power source, two main methods are used: shema soedinenija avtomatov

: They offer better contact area, reduce panel clutter, and handle higher currents (e.g., matching a 63A main switch ). : According to PUE section 3

: Daisy-chaining jumpers can lead to fire hazards because the first wire in the chain must carry the combined current of all subsequent circuits. 3. Circuit Configuration Types Pin-type VS Fork-type Comb Busbars: Differences : According to PUE section 3.1.6

: These are pre-insulated copper bars with "teeth" that slide into the terminals of multiple breakers simultaneously.

While many modern breakers are universal, standard practice and regulations often dictate where the "supply" wire should be connected.
