How to replace a tube on the machine

Protection of the network using the congestion is not only archaic but also dangerous in that case if the burnt tube is reduced by a "bug" (podmochennoy thin wire). The availability of automatic protection not only protects the wiring from short circuits, but also allows, if necessary, easily and quickly it to disconnect.

To replace the tubes in the machines, you do not need to call an electrician to take any permission – tubes are on the output of the counter, so you can do it yourself. But be careful when changing plugs do not damage the seals, sealing the electric meter.

You will need to install two breaker, one for phase wire and the zero. Choose machines protection on the basis of the estimated load. In most cases, used machines protection to 16 or 25 amps.

First, remove the old tube. To control the phase conductor, use a probe, usually the phase is left extending from the meter wire. Carefully Unscrew the screws, if necessary, use rubber gloves to prevent electric shock. Watch carefully that the phase wire accidentally touched zero!

To install machines protection, you will need a DIN-rail – a special profile, aluminum or steel. Automatic protection can be installed close to each other, so stop with a six-inch cut strips. Secure it with the screws horizontally in the place where there will be automatic machines of protection.

Pulling on the machine protection latch, hang it vertically on a DIN rail, the letters "On" should be at the top. In the same way and install a second machine. Then connect the wires, while the machines should be in the off position. Please note that the wires coming from the electric meter must be suitable to the upper terminals of the circuit breaker protection. The wire to the housing of the network connected to their lower terminals. Tighten the screws, otherwise the terminal can bask at high load. The installation of machines for the protection is finished.
