The utility model discloses a six way efficient device for assembling and disassembling a meter without power-off. The device includes an insulation fixing seat, a conductive support, a conductive inlet wire connecting piece, a conductive outlet wire connecting piece and a wiring rod. By adopting the six way efficient device for assembling and disassembling the meter without power-off, assembling and disassembling an electric energy meter can be achieved without power-off, so as to greatly save outage cost caused by powering off when the meter is assembled and disassembled, prevent inconvenience for users, and raise the quality of power supply.
