AWG stands for "American Wire Gauge" being this a measure used to represent the width and section measurements of cables.

Here is an AWG conversion table:

A rack is a metal support designed to house electronic, computer and communications equipment. The measures for the width are normalized to be compatible with most equipment manufacturers. They are also called racks, cabinets, cabinets or closets. Each column has holes at regular intervals called U rack units (Pictured: 4) grouped in threes. The height (Pictured:5) of the racks is standardized and external dimensions of 200 mm by 200 mm. Being normal that from 4U to 46/47U height width types (Pictured: 7). Standard 600 mm or 800 mm Types of background (Pictured: 6) The depth of the frame is not standardized, as this flexibility is granted (Pictured: 8) to the equipment. The most common are: - 450 mm - 600 mm - 800 mm - 900 mm - 1000 mm - 1200 mm Type 19-inch rack can find various types of 19-inch rack. Rack Mural (Pictured: 2): Used to accommodate electronic network. They are the smallest and are anchored to wall. Rack Pie (Pictured: 1): They are used primarily for servers, UPS and network electronics. Open Rack (Pictured: 3): Open Rack Racks are available only modelsstructure, eliminating doors and other accessories.

IEC connector is the common name for a set of thirteen power connectors (called the connector specifications) and thirteen outlet panels (called input) specification defined by IEC 60320 (formerly IEC 320) of the International Electrotechnical Commission ( IEC). When used without other qualifiers, "IEC connector" usually refers specifically to the C13 and C14 connectors.

In IEC connector or cable with a base (usually plastic) and a plug to connect to the socket (plug), if we put these two things we would get the named SCHUKO is the overall connector. The schuko not determine the type of connector. It would be determined by the specification of the International Electrotechnical Commision (IEC). We leave a small sample of Schukos internationally.

When carrying out an electrical installation or electrical circuit several factors must be taken into account, one of them is the selection of the appropriate cable. According to the installation and the use of the same we can find different diameters that support different loads. The cable section will also help us not to overheat our installation, since the larger the section, the greater the thermal resistance.
In the following table poWe can see the corresponding load supported for the different sections of cables.

Within the different types of electrical cables we can find single or multifilament cables. The difference lies in the number of conductors that make up the cable. Single wire cables contain only a single conductive wire, whereas multi-wire cables contain more than one wire. Do not confuse multifile (A) or single wire (B) with monopolar (C), bipolar (D) or multipolar (E) cable. Monopolar cables have only oneSingle conductor, bipolar cables have two conductors, while multi-pole cables have more than two conductors. It may be said that any unipolar, bipolar or multipolar cable can be single-ended or multi-stranded. In the case of single wire cables we will talk about rigid cables, whereas the multifilament cables will be flexible.
In the following table you can see the difference between them.

As it is common in installations we can find a standard of colors in the electric cables.

These regulations help at a glance to understand the connection and the resolution of possible faults or failures.

Below we attach the color/cable relation for electrical installations.

1. The ground wire can be identified in several ways:
• Green cable.
• C cablegreen smell with a yellow line.
• Cable without insulation.
2. The neutral wire will be blue.
3. The phase cable can be identified in several ways:
• Any color different from neutral or earth.
• Black insulation.
• Brown isolate.
• Gray insulation.

The insulating or insulating tape is a fundamental element when making a repair or performing an electrical installation. The insulating tape will help us to protect and insulate the electrical cables from possible crossings or contacts between them or with other elements, guaranteeing that the connection is well insulated avoiding possible short circuits.
Its use is very simple, since being a flexible material allows us to apply it with comfort.
To achieve a perfect union, it is recommended that we wrap the tape covering half the cable and half over the joint, stretching the tape slightly while rolling obliquely.

• For the ground wire, colored insulation tape will be used:
• Green.
• Green with a yellow line.
• For the neutral cable, blue insulating tape will be used.
• For the cable the phase isYou can use any other color:
• Any color different from neutral or earth.
• Black insulating tape.
• Brown insulating tape.
• Gray insulating tape.
