Which factor is important when selecting a location for a distribution board in domestic wiring?
Proximity to the load centre.
The correct siting of a distribution board is governed by the electrical goal of feeding all connected loads with the least voltage drop and the least conductor material, which points to the electrical load centre of the installation.
The load centre is the point about which the connected loads are electrically balanced, so a board placed there has the shortest overall run of cable to the various sub-circuits.
Short cable runs mean lower voltage drop at the far ends, smaller copper (I²R) losses in the wiring and less cable cost, while also giving safe and convenient access for switching and protection.
The brand of the board is only a purchasing choice and changes nothing about where current must flow, so it cannot fix the correct position.
The type of wiring (conduit, casing-capping, etc.) affects the method of installation but not the electrically ideal location of the feed point.
The mere number of rooms describes building size, not where the loads concentrate; two large rooms can outweigh several small ones, so a room count does not locate the load centre.
Hence, the answer is Proximity to the load centre..
