In order for household appliances and electrical appliances to do not fail your home and do not provoke fire hazardous situations, you can install an RCD. These devices carry out a protective shutdown. If you live in new buildings, then you must install them without fail. They are soldered to mount in shields of apartments and electrical panels of private houses. This will protect the residents from an unexpected shock.
You can purchase these devices in specialized stores. If you plan to buy an RCD, you should not become a decisive factor for acquiring this device. It is important to know exactly which device is suitable for your home.
Distinguish between two forms. They can be single -phase or three -phase. You need to choose the option that will fit into your network. Everything is relatively simple here. If your network has one phase, then the RCD should occupy two modules, including the phase and zero. In the event that it is three -phase, then it will take four modules better. It will be three phases and zero.
Some housing owners doubt that this device must be installed. In this case, there should be no doubt. Experts advise to install an RCD in any case.
You must also select an RCD for your home, focusing on the rated current. Some manufacturers produce products with a certain rated current. They are mounted on a din-rack. The value of the rated current determines what current this product can pass during an unlimited time without any loss of quality.
In addition, you should know that this device does not protect against excessive currents such as a short circuit. Put another auto switch.
