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.

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.

Nowadays we all have in mind the importance of controlling and verifying the bills we receive in the stores. Thanks to the different security systems implemented and the renewal of protection systems in the new current tickets, it becomes increasingly difficult to falsify, but still an extra control is highly recommended.
Counting systems or banknote detectors use the combination of vArias detection technologies to check if the ticket is false or the ticket is true.
Among the detection systems we find from the simplest (pen) to machines that verify different characteristics of the ticket to verify their authenticity.
The most common detection systems are:

1. LABEL: Simply mark the ticket to check. If the mark is displayed in black, the billetAnd is false.

Detecting machines: The most reliable, as they can combine different detection technologies such as:

1. UV: Ultraviolet detection. It allows in a visual way to verify the markings integrated in the ticket with fluorescent phosphors that can not be seen in daylight and are only visible with an ultraviolet light at a certain frequency.
2. IR: Infrared light detection: Other systemOf safety implemented in the tickets is their ink, since under a type of infrared light they exhibit a special behavior. There are two types of ink, the ink that shines when exposed to an IR light and the ink that does the opposite and absorbs the light giving a black tone.
3. MG1 and MG2: This is the magnetic detection. The tickets incorporate a magnetic security system, which is based on a band usually on the sideOf the note, of a ferromagnetic material. This security system is not visible without the proper detector. Another safety system based on magnetic detection is to print the bill with areas of magnetic ink.
4. SIZE: It is based on the detection of the ticket checking its size in length and width. Each ticket has some special characteristics and very specific in terms of measurement, each one of them is fabriTo the millimeter.
5. DD: Thickness detection. Just as each ticket has an exact size, they also have a specific thickness.

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.
