FIELD: electrical engineering.
SUBSTANCE: technical result is achieved due to that electricity distribution circuit intended to supply at least two loads (CH1, CH2, CH3) from two sources (S1, S2), comprises conductors F1-F11, some of which (F3, F4, F5, F1, F2) form outputs capable of being connected with external equipment, and switching devices (H1, H2, H3, H4, H5, H6), arranged to establish a path between each load (CH1, CH2, CH3) and two sources (S1, S2), by connecting said loads and sources with the outputs, (F3, F4, F5, F1, F2), characterised in that, for at least one pair of said loads (CH1, CH2) two switching devices on paths (H1, H2) (H3, H4), connecting each source (S1, S2) with two loads of said pair (CH1, CH2), are incorporated into double flow switch (I1, I2), said double flow switch (I1, I2) being connected at midpoint (K4, K5) with output (F1, F2), intended to be connected to corresponding source (S1, S2). Invention also relates to an apparatus that uses this circuit, and to a method for manufacturing it.
EFFECT: technical result is high fault tolerance.
