Abstract
A device for use with an electricity meter is selectively moveable between first and second positions. The device comprises a fuse support capable of holding a fuse in a fuse position. The device is arranged such that, when in the first position, the fuse position is located relative to first and second circuits such that when a fuse is held in the fuse support the first circuit is closed and the second circuit is open. The device is further arranged such that moving the device from the first position to the second position causes the fuse position to be relocated relative to the first and second circuits such that the first circuit is opened and the second circuit is closed.
Claims20
A device for use with an electricity meter, the device being selectively moveable between first and second positions, and the device comprising:
- a fuse support capable of holding a fuse in a fuse position, wherein the device is arranged such that, when in the first position, the fuse position is located relative to first and second circuits such that when a fuse is held in the fuse support, the first circuit is closed and the second circuit is open, and wherein the device is further arranged such that moving the device from the first to the second position causes the fuse position to be relocated relative to the first and second circuits such that the first circuit is opened and the second circuit is closed, wherein the first circuit connects the electricity meter and an auxiliary device, and when the first circuit is closed the auxiliary device is connected before the electricity meter such that the electricity meter does not register electricity consumption of the auxiliary device, wherein the second circuit connects the electricity meter and the auxiliary device, and when the second circuit is closed the auxiliary device is connected after the electricity meter such that the electricity meter registers electricity consumption of the auxiliary device.
A method of selectively opening and closing first and second circuits connecting an electricity meter and an auxiliary device, comprising:
- providing a device with a fuse support capable of holding a fuse in a fuse position;
- engaging the fuse with the fuse support such that the fuse is held in the fuse position;
- and
- moving the device from a first position to a second position or moving the device from the second position to the first position, wherein:
- when in the first position, the fuse position is located such that the first circuit is closed, the second circuit is open, and the auxiliary device is connected before the electricity meter such that the electricity meter does not register electricity consumption of the auxiliary device;
- and
- when in the second position, the fuse position is located such that the first circuit is open, the second circuit is closed, and the auxiliary device is connected after the electricity meter such that the electricity meter registers electricity consumption of the auxiliary device.
A device for connecting a fuse to a circuit associated with an electricity meter such that electricity consumption for an auxiliary device is measured at the electricity meter when the device is positioned in a first orientation and electricity consumption of the auxiliary device is not measured at the electricity meter when the device is positioned in a second orientation, the device comprising:
- a first leg disposed at a first end of the device;
- a second leg disposed at a second end of the device;
- a crossbar connected to the first leg and the second leg;
- and
- a fuse support connected to the crossbar and disposed between the first leg and the second leg, the fuse support to removably receive the fuse, the fuse support being arranged to position the fuse closer to the first leg than the second leg when the fuse is received in the fuse support.
