When creating electrical wiring from 10 to 20 Amperes, special attention should be paid to the cleanliness of the cable tips. It is recommended to protect such networks with a circuit breaker with the appropriate characteristics (up to 10, 13, 16 or 20 Amperes). In this case, the wire cross-section should vary in the range from 1.5 to 2.5 mm.
If the current is expected to pakistan email list 2.5 million contact leads exceed 25 Amperes, it is advisable to limit the use of WAGO terminal blocks. In such situations, it is better to use soldering, welding or crimping of cables. For quick maintenance and repair of home electrical networks, WAGO terminal blocks are the most convenient option.
That professional electricians Operating instructions
In the WAGO line, the most popular terminal blocks are those belonging to the 221, 222 and 773 series. These are the ones installers usually have in mind when talking about cable connectors.
The 222 series devices belong to see why good seo optimization is so important the category of construction and installation terminal blocks. This is a good choice for creating multiple (detachable) connections of single- and multi-core cables. The conductor is fixed using a special lever, which is also used to disconnect the contact. Before inserting and snapping the wire, it is necessary to remove the insulation from it using a special tool. The operating principle of the device is based on the use of a flat-spring clamp.
The 773 series devices should be used
To create single-use (non-detachable) connections, and only from single-core wires. If a multi-core cable is required, it must first be crimped mobile lead using tips. Connectors of this series are available in two versions: with conductive paste, which is installed at the factory, or without it. The advantage of terminal blocks with paste is that it prevents the formation of an oxide film on aluminum wires. Such devices are black or dark gray. During installation, the core is inserted to the limit, after which it is automatically fixed with a non-detachable internal clamp.
