The invention discloses an arrayed incoming-line six-way type device for fastly assembling and disassembling an ammeter in a non-outage way. The device comprises an insulated fixed base, a conductive bracket, a conductive incoming line connector, a conductive outgoing line connector and a wiring bar. With the adoption of the arrayed incoming-line six-way type device for fastly assembling and disassembling the ammeter in the non-outage way, the assembly and disassembly of the ammeter can be realized on the condition of not interrupting a power supply, the outage cost caused by the assembly and disassembly operations carried out only under power outage in the prior art is greatly saved, the inconvenience brought to customers is also reduced, and the power supply quality is improved.
