How to cut off the voltage?

Question

network hardware

There is a very specific problem. In one public place, a socket was allocated for connecting network equipment on the roof. According to the requirements of the building owners, the outlet must be open. Before it is a counter. To pay for electricity consumed. Repeatedly caught disconnection of equipment from electricity. The equipment goes to the battery, and local electricians connect to it and wind the electricity with their dark deeds. And not only them. And then they stick back. The closet is not mine and I cannot do anything before the counter. And I also cannot place the socket under the key or remove it. I can't move equipment either. And so, with difficulty, permission to install was knocked out from the administration. The owners of such garbage, as everyone understood, are far from delighted. In short, here's the problem. We got a very large electricity bill. During the month, they often turned off and they did something. We get to pay. Is it possible to mount a device that cuts off the phase in the outlet after the consumer has been pulled out? And to turn on it was possible only with handles. And I will lock this device on a turn-key basis. Are there inexpensive solutions?

Answer 1

Well, the starter can be installed. Power the coil from the "consumer", put a shunted button inside.
ps if the load is small, you can just put a 1 ampere machine in the cabinet and that's it. If you try to connect a load of more than 220 watts, it will cut off. You can put a current relay , which will cut off the load when the current is exceeded (if you have a large load connected, then the solution does not make sense).
The starter can also be connected like this:

Answer 2

Install an American standard socket. Of course, you can find an adapter or make it yourself, but it’s not so easy.))

Answer 3

The meter is in the wrong place, move it to the point between the outlet and your equipment - you will only pay for your electricity costs.
And you also need to disassemble the outlet, connect the wire, assemble the outlet, pull the connected wire to the equipment - it will become unplugged.

Answer 4

The most correct option is a socket and a plug-in meter. Even if the outlet is turned off, no one will interfere with plugging in bypassing the outlet.
Options for a simpler relay or automatic machine for low current or put a socket under the "Chinese" wire. But all this only complicates, but does not exclude the connection past your stray.

Answer 5

outlet must be open.

Make a "pseudo-socket" into a non-retractable plug.
Remove the socket housing.
Disassemble the fork.
Weld the pins from the plug to the socket contacts.
Put back the socket housing.
Assemble the body of the plug on the protruding pins.
If there are claims - tell me what was welded from the short circuit.

Answer 6

The above idea with a reed switch and a magnet can be developed further: The reed switch does not turn on the alarm, but turns on the contactor and voltage appears on the outlet.

Answer 7

the cheapest way is to put a seal on the plug of your equipment and make you pay for every break. a filling is not a piece of adhesive tape, so you understand)))

Answer 8

1. Make a claim to the owners of the building. Renew the contract with the provision of a dedicated electric line.
2. Connect the equipment with a wire in a metal pipe/corrugation. They stick needles into ordinary wiring and steal, I saw this.
3. Connect an open socket with a separate wire from the common meter. Let everyone pay for public use.
