: High-quality brands like ABB or Legrand may allow input from either side, but keeping a consistent "top-in, bottom-out" pattern across the panel is crucial for safety and easier troubleshooting. 2. Linking Multiple Breakers
While many modern breakers are universal, standard practice and regulations often dictate where the "supply" wire should be connected.
When connecting several breakers to a single power source, two main methods are used:
: They offer better contact area, reduce panel clutter, and handle higher currents (e.g., matching a 63A main switch ).
: These are pre-insulated copper bars with "teeth" that slide into the terminals of multiple breakers simultaneously.
: Pin-type (universal pole structure) and Fork-type (U-shaped for screw terminals).
: According to PUE section 3.1.6 , supply wires should ideally be connected to the static (stationary) contacts , which are almost always at the top of the breaker.
