Instalasi Penerangan Listrik 12

Grounding pada instalasi rumah berfungsi sebagai proteksi peralatan elektronik saat terjadi kebocoran tegangan dan listrik dialirkan ke tanah. Dengan grounding, jika terjadi kebocoran tegangan atau hubungan pendek, arus listrik akan dialirkan ke tanah melalui grounding, sehingga mengurangi risiko terjadinya kerusakan pada peralatan elektronik dan melindungi pengguna dari bahaya kejutan listrik.

Kaos kaki bukanlah alat pengaman yang harus digunakan oleh pekerja listrik. Alat-alat pengaman yang harus digunakan oleh pekerja listrik meliputi sabuk keselamatan, kaca mata, dan sarung tangan. Kaos kaki mungkin penting untuk melindungi kaki pekerja, tetapi tidak secara khusus berkaitan dengan keamanan saat bekerja dengan listrik.

The correct answer is Kwh meter - MCB - Box sekring - peralatan listrik. This is the correct sequence for the installation of electrical components. The Kwh meter is the first component to be installed, followed by the MCB (Miniature Circuit Breaker), then the Box sekring (fuse box), and finally the peralatan listrik (electrical equipment). This sequence ensures that the electrical supply is properly regulated and protected, with the Kwh meter measuring the energy consumption, the MCB acting as a safety device, and the fuse box providing additional protection. The electrical equipment is connected last to ensure proper functionality and safety.

The correct answer is Kwh meter dan MCB. Kwh meter is used to measure the amount of electrical energy consumed in kilowatt-hours, while MCB (Miniature Circuit Breaker) is a device that automatically switches off the electrical circuit during an overload or short circuit. Both devices are used for measuring and limiting electrical consumption and ensuring safety in electrical circuits.

The correct answer is inbow dan outbow. Inbow dan outbow adalah teknik pemasangan kabel yang biasa diterapkan di rumah. Inbow digunakan untuk menghubungkan kabel dari luar rumah ke dalam rumah, sedangkan outbow digunakan untuk menghubungkan kabel dari dalam rumah ke luar rumah. Dengan menggunakan kedua teknik ini, kabel dapat terpasang dengan rapi dan aman di dalam rumah.

The correct answer is "Mempersiapkan gambar denah instalasi." When installing electrical installations, it is important to have a plan or blueprint of the installation. This plan, known as a denah instalasi, provides a guide for the placement of electrical components and ensures that the installation is done correctly and safely. By preparing the denah instalasi beforehand, it helps to avoid any confusion or mistakes during the installation process.

The correct answer is 10. The question asks for the amperage of the MCB (Miniature Circuit Breaker) that should be installed in a house with a power of 2200 watts. To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, assuming the voltage is 220 volts (common for household electricity), the amperage would be 2200 / 220 = 10 amps. Therefore, the correct answer is 10.

The correct answer is "elektrode kayu" because wood is not a suitable material for grounding electrodes. Grounding electrodes are typically made of materials such as copper, steel, or aluminum, which have good electrical conductivity. Wood does not have the necessary conductivity to effectively dissipate electrical charges and provide a safe grounding system.

The correct answer is "semua benar" which means "all correct". This means that all of the statements mentioned in the options are true. The principle of K3 (Keselamatan dan Kesehatan Kerja) refers to knowing and understanding the work, knowing the potential hazards of a job, and the necessity of always working with personal protective equipment.

The correct answer is AVO meter and mechanical hand tools. An AVO meter is used to measure voltage, current, and resistance, which is necessary to diagnose and troubleshoot electrical issues. Mechanical hand tools are needed to physically repair the damaged insulation and ensure the safety of the electrical appliance.

Perbaikan faktor daya adalah suatu usaha yang dilakukan agar daya rata-rata mendekati nilai daya nyata. Ini berarti bahwa tujuan dari perbaikan faktor daya adalah untuk mendekatkan daya yang sebenarnya dengan daya yang seharusnya. Dengan melakukan perbaikan faktor daya, kita dapat meningkatkan efisiensi penggunaan daya listrik dan mengurangi pemborosan energi.

The given description mentions that the cable has a white PVC outer insulation, with rubber sheathing inside, and a single core wire with 2-4 cores, each having different colored PVC insulation. These characteristics match the specifications of NYM cable.

The given options NYY, NYA, NYFGb, and NYN are all types of cables. However, the question asks for the exception, so the correct answer is NYN.

NYY cable is the most suitable for outdoor use that is frequently exposed to rain because it is designed with a weather-resistant outer sheath. This outer sheath provides protection against moisture and other environmental factors, making it ideal for outdoor installations. NYA, NYM, and NYC cables do not have the same level of weather resistance as NYY cable, so they may not be as durable or reliable when used in outdoor environments.

The correct answer is "ekonomis-keamanan-keandalan". This answer suggests that the installation of electrical systems should meet the criteria of being economical, safe, and reliable. This means that the electrical installation should be cost-effective, ensuring that it is affordable and efficient. Additionally, it should prioritize safety to prevent any potential hazards or accidents. Lastly, the installation should be reliable, ensuring that it functions properly and consistently.

The given answer, "Ruangan dengan intensitas curah hujan rendah" (Rooms with low rainfall intensity), is not a requirement for standardizing installations in special rooms to avoid electrical hazards. The other options - installation in humid rooms, rooms with high gas levels, and dusty rooms - are all potential hazards that need to be considered and addressed in order to ensure the safety of the installation.

The correct answer is NYY. NYY cable is suitable for direct burial without conduit because it is designed with a protective layer that can withstand the harsh conditions underground. NYA and NYM cables are not suitable for direct burial without conduit as they do not have the same level of protection. Therefore, the correct answer is NYY.

The correct answer is 1%. According to PUIL (Peraturan Umum Instalasi Listrik), a 1% voltage drop is allowed in electrical installations. This means that the voltage can decrease by up to 1% from the source to the load. This allowance accounts for losses that occur due to resistance in the electrical wires and components.

The correct answer is hitam. According to PUIL 2000, the color of the cable for the phase conductor in a single-phase network is black.

This answer suggests that the principle of lightning protection involves directing the lightning from the roof to the ground. This is an important aspect of lightning protection systems as it helps to prevent damage to the building and its occupants by safely channeling the electrical current away from the structure. By providing a path for the lightning to follow, such as through a lightning rod or conductive materials, the risk of a direct strike and its associated dangers can be minimized.
