PROBLEM TO BE SOLVED: To provide a connection box which helps to reduce manufacturing costs and makes it possible to prevent erroneous operation.SOLUTION: A connection box 170 for connecting a plurality of solar cell arrays to a power conditioner comprises: a DC circuit breaker 105; a plurality of DC disconnecting switches 102 for breaking connections between the plurality of solar cell arrays and the DC circuit breaker in units of array; a connection box body 120 for accommodating the DC circuit breaker and the plurality of DC disconnecting switches therein; and a cover 106 fixedly journaled at one end to the connection box body and used to cover the DC circuit breaker and the plurality of DC disconnecting switches. The DC circuit breaker has a lever 1051 which, while being tilted to the OFF side, collectively cuts off a current from the plurality of solar cell arrays to the power conditioner and, while being titled to the ON side, collectively releases the current cut-off. The cover has a hole 1061 which is constructed so that the cover, while covering the DC circuit breaker and the plurality of DC disconnection switches, interferes with the lever when the lever is tilted to the ON side and does not interfere with the lever when the lever is tilted to the OFF side. |
