Distribution board for electrical installations in which an incoming three-phase system is to be distributed to one-phase and three-phase conductor race ways, comprising a preconnected bus system (5R, 5S, 5T) which distribute the three incoming phases (R, S, T) in rows (RO) and columns (CO) of race way connection points (16), so that the phases (R, S and T) are alternated in cyclic sequence both along the rows (RO) and the columns (CO) of the connection points (16). A distribution board having such a bus system renders smaller design dimensions, and the electrician does not during the installation have to think of the allocation of the race ways on the individual phases, said phases (R, S and T) always having the correct sequence in horizontal and vertical direction. |
