Multi-circuit breaker arrangement method for power distribution cabinet or power distribution box

The invention provides a multi-circuit breaker arrangement method for a power distribution cabinet or a power distribution box. In a box body of the power distribution cabinet or the power distribution box, multiple circuit breakers are arranged on an adaptor in upper and lower two rows, and are arranged in the box body of the power distribution cabinet or the power distribution box through the adaptor; and incoming lines and outgoing lines of the upper and lower two rows of circuit breakers are transferred through the adaptor. The multiple circuit breakers are arranged on the adaptor in upper and lower two rows, namely multiple circuit breakers are arranged in upper and lower two rows through the adaptor; and two of the multiple circuit breakers are taken as a group and two circuit breakers in each group are arranged on the adaptor in an up-and-down arrangement manner. By a plug-type adaptor, arrangement of the multiple circuit breakers in upper and lower two rows is achieved; the transverse structure size of the power distribution cabinet (box) is greatly reduced; hidden connection of the incoming lines and the outgoing lines is achieved through the adaptor; and an exposed copper wire of an overall circuit breaker system cannot be seen from the appearance, so that the installation degree can be greatly improved; and the appearance after transferring is relatively beautiful.
