In general, measurement refers to the recording of dimensions and quantities of an object or a construction. It is used to obtain precise information about the actual condition and forms the basis for further planning and calculations.

In the electrical industry, measurement is applied specifically to electrical installations and equipment. It includes the measurement and documentation of electrical lines, cables, switches, distribution boards, switch boxes and other electrical components. Measurement in the electrical industry makes it possible to obtain accurate information about the lengths of cables, the positioning of switches and distributors, the number of sockets, and other details.

Measurement in the electrical industry is important for several purposes:

1. Planning: By accurately measuring electrical installations, detailed plans can be created to serve as the basis for planning new installations or renovations.
2. Calculation: The measurement makes it possible to calculate the required quantities of materials such as cables, switches, sockets, etc. in order to make accurate cost estimates.
3. Documentation: Measurement provides an accurate record of existing electrical installations, useful for future reference, maintenance, or alterations.
4. Safety and Compliance: The survey can verify that the electrical installations comply with applicable safety standards and regulations.

The measurement in the electrical industry is usually carried out by electrical specialists, electrical engineers or electricians who have the necessary expertise and experience in electrical installation technology.

In the field of billing, measurement plays an important role, especially when it comes to costing construction projects. Once the measurement has been carried out and accurate information is available on the dimensions and quantities of the electrical installations, this data can be used to calculate the costs of material procurement and labor.

The recorded measurement data allows billing departments to create accurate cost estimates. They can use the lengths of wires, number of switches, outlets, and other electrical components to determine the quantities of materials needed. Based on current market prices of materials and labor hour costs, the total cost of electrical installation can be calculated.

Measurement also plays an important role in reviewing invoices and billing for services rendered. By comparing the work actually performed on the job site with the recorded measurement data, discrepancies, or discrepancies can be identified. This helps to create accurate billings and ensure that the work actually performed is recorded and paid for correctly.

In summary, in the electrical industry, measurement is not only important for planning and documenting electrical installations, but also has a direct impact on costing and billing of construction projects. It enables accurate cost estimation, verification of services rendered and preparation of correct invoices.

NYM cables are suitable for fixed installation indoors as well as in dry, damp and wet rooms, but not in the ground or unprotected outdoors. They have PVC insulation and a PVC sheath. NYY cables are more robust and designed for underground and outdoor installation, as they have thicker insulation and a stronger sheath to withstand mechanical and weather-related influences. You can often find these cables at your local electrical retailer.

When selecting an electrical cable, you should consider several factors:

• Intended use: Whether the cable is intended for indoor or outdoor use or for underground installation.
• Electrical load capacity: How much current the cable must carry.
• Mechanical load: Whether the cable is exposed to mechanical influences such as pressure or tensile forces.
• Ambient temperature: The temperature ranges in which the cable is used.
• Standards and regulations: Does the cable fulfil all relevant legal and normative requirements (e.g., VDE, IEC).

These factors can also be explained to you by the experts at a specialized electrical retailer in order to make the best choice for your project.

H07RN-F cables are extremely robust and flexible. They are resistant to oil and mechanical loads, which makes them ideal for mobile applications in industry and on construction sites. In comparison, NYM cables are less flexible and mainly intended for fixed installations in buildings. You can purchase both types of cable from a specialist electrical retailer, where qualified personnel can help you make the right choice.

You should use an underground cable such as the NYY cable if it is necessary to lay the cable in the ground. These cables are designed to withstand mechanical stress and moisture, making them ideal for supplying power to outdoor installations and buildings. You can also find information on specific underground cables at your local electrical retailer.

The cable cross-section is decisive for the current-carrying capacity and the voltage drops in the cable. A larger cross-section means a higher current-carrying capacity and lower voltage drops. For standard installations in residential buildings, NYM 3x1.5 cable is often used, which is sufficient for most light and socket circuits. Specialist electrical retailers can help you select the right cross-section for your specific requirements.

By the way: The Aufmaster can measure any cable that has a cable cross-section of at least 0.25 mm² and at least two metallic conductive cores. You can replace our standard terminals (WAGO through-connectors up to 4 mm²) with other terminals at any time.

Installation cables such as NYM are intended for fixed installations in buildings and have PVC insulation. They are not suitable for mobile applications. Rubber cables such as H07RN-F are flexible and intended for mobile and temporary installations, with a rubber insulation that makes them resistant to mechanical stress and oil. Both cable types are available from specialized electrical retailers.

Various national and international standards apply to the installation of electrical cables. In Germany, for example, these are the VDE regulations, which ensure that cables are installed and operated safely. International standards such as the IEC standards apply, which define similar safety requirements. Your specialist electrical retailer can provide you with specific information and the appropriate products that fulfil these standards.

You may only carry out measurements with the Aufmaster if the cable is completely de-energised! Further safety instructions can be found in our operating instructions in the help section.

The ambient temperature affects the insulation and the service life of the cable. Cables must be designed for the specific temperature conditions in which they are operated. NYM 3x1.5 cables, for example, can be used in a temperature range from -40°C to +70°C. Specialist electrical retailers offer a wide range of cables for different temperature requirements.

The ambient temperature in the processing area of the cable is documented by the Aufmaster if required.

When laying cables outdoors, they should be mechanically protected, for example by laying them in protective conduits or cable ducts. The cables should also be UV-resistant to prevent damage caused by solar radiation. NYY cables are well suited for such applications and can be purchased from a specialized electrical retailer.

The Aufmaster has a protection class of IP54. It is therefore protected against splash water and can withstand heavy dust and dirt.

The standard cable for house wiring is NYM 3x1.5 cable. It is used because it is sufficiently dimensioned for most light and socket circuits in residential buildings. It is easy to lay, flexible enough for most installation requirements and offers reliable performance for general domestic installations. These cables are widely used and readily available at any electrical retailer.

We can only confirm this popularity: NYM 3x1.5 also tops the Aufmaster ranking of the most commonly installed cables.

When using NYM 3x1.5 cables, you must observe VDE standards and other relevant safety regulations to ensure safe installation. These include correct installation, protection against mechanical damage and compliance with the permissible load. These regulations ensure safe operation and the longevity of the installation.
