Selection notes
For an LV switchboard the busbar current and the fault level decide the design. Collect the transformer or generator rating, the incomer current and the prospective short-circuit current at the board, since the busbar and breakers must withstand it for the stated duration.
- Incomer device: large incomers are usually an ACB; outgoing feeders commonly use an MCCB. Ask for the overload and earth fault settings you need.
- Form of separation: IEC 61439 describes forms 1 to 4. A higher form limits the spread of a fault and eases maintenance, at higher cost.
- Bus coupler: add one if two incomers must feed the same loads.
Typical mistakes are sizing the bus only to today's load, no spare outgoing ways, and forgetting the ambient temperature, which derates the board. Decide early about metering, power factor and how the board links to the transformer, for example through a bus duct. A qualified engineer should confirm ratings against your system study.

Frequently asked questions
How do I choose between ACB and MCCB feeders in a low voltage panel?
ACBs are used for large incomers and bus couplers because of high current rating, adjustable protection and withstand capacity. MCCBs suit outgoing feeders and smaller loads. The cut-over point depends on current and fault level, so share the load schedule and we can suggest a split.
What does form of separation mean in an LV panel?
It describes how busbars, functional units and terminals are partitioned inside the assembly, from form 1 with no internal separation up to form 4 with separate compartments per unit. Higher forms improve safety during maintenance but increase size and cost.
