Flexibility and Accessibility: Facilitate easier upgrades, repairs, and maintenance by providing accessible pathways for electrical cables. Installation Considerations Conduit Sizing: Ensure the conduit size is adequate to accommodate the number of cables without overcrowding. Bends and Joints: Use appropriate fittings, bends, and joints to navigate around obstacles and maintain the integrity of the conduit system. Support and Securement: Properly support and secure conduits to the building structure to prevent sagging or movement. Environmental Factors: Consider environmental factors such as moisture, temperature, and exposure to chemicals when selecting the type of conduit. Conclusion Conduit pipes, or CD pipes, play a crucial role in the safety, organization, and durability of electrical installations in MEP systems. By providing protection and maintaining orderly routing of electrical wiring, conduits help ensure reliable and compliant electrical systems in various building types, including residential, commercial, and industrial projects.

When you ask for a job to be completed in the construction industry you will normally need a survey. 👨🏻🔧 A survey can be anything from a few minutes with a conversation to a full M&E design taking several weeks/ months. 📐 📖 💻 This can cost thousands of pounds and take hundreds of hours to complete. Depending on the size of the project this cost will normally be passed onto the client. At JGF Electrical this is also the case. However where we differ from other contractors within the industry is that our surveys will not hide or withhold any information. Each section will include labour and material breakdowns. Materials will also include part numbers and model numbers. This is simply being transparent. 🔍 Survey and design documents can then be used and passed onto other contractors to gain comparison quotations. Remember, the client has paid for these documents. See our previous blog on what makes a great quote. ⬇️ https://lnkd.in/eAn59MDG #Quotation #Survey #Design #electrical #electricalcontractor

To be honest with you, the planning and installation of LV switchgear is a damn complicated job. But you knew that :) There are dozen of detail where you can stumble, if not planned carefully as they should be. The later installation phase (and not to speak about commissioning phase) largely depends on the in-detail planned first phase, which usually includes the organization of transportation, design of switchgear room and clearances, various civil works, safety against arcing faults, and so on. An old saying “The devil is in the detail” actually perfectly fits here. This technical article will try to shed some light on some tricky details which can be in some situations a project saviour.

Let's talk fence isolation for a minute with substation grounding systems. When substation fences are attached to fences outside the substation they often need to be isolated to mitigate the transferring of potential out or into a substation when designing the substation grounding system. The isolation can come in many forms from using sections of metallic fence that is insulated between the two fencing systems, the use of non-metalic fence panels or like this photo a simple piece for lumber. Early in my career (early 2000's) the use of wood (like this photo) was common in designs I was involved with when I worked at an engineering firm as that is what the client wanted. I had also seen and used metallic fence that was isolated for maybe one section of a certain length with insulators both ends of the section. The use of wood when this was installed (year of installation not known) was likely before modern software tools and testing techniques and an attempt by the designer to have isolation. I won't get into any specifics of this installation but just wanted to share that fence isolation can come in many forms and that they can be evaluated using modern software and/or testing techniques. I am by no means an expert in this area but continue to learn more about it.

#Earthingsystems; Principles, Types, Design Considerations & Maintenance Earthing systems are essential for ensuring the safety and reliability of electrical systems. These systems provide a low-resistance path to the earth, ensuring that fault current flows to the ground instead of through people and equipment. Earthing systems must comply with relevant electrical standards and regulations to ensure proper functionality and safety. Principles of Earthing Systems: - The primary purpose of an earthing system is to provide a low-impedance path for the flow of fault current to the earth, ensuring the safety of people and equipment. - The earthing system also helps to stabilize the voltage level and reduce the risk of electrical shock or fire. Types of Earthing Systems: - TT System: Connects the electrical equipment to the earth via an electrode or earth rod, ensuring a direct connection to the earth. - TN System: Connects the neutral point of the power supply to the earth, creating a low-impedance path for the flow of fault current. - IT System: Isolates the electrical equipment from the earth, providing a high level of protection against electrical shock. Design Considerations for Earthing Systems: - Measure soil resistivity of the earth electrode to ensure adequate grounding resistance. - Select the type of earthing system based on the specific requirements of the installation, such as power supply configuration, location, and size. - Periodically inspect and test the earthing system to ensure proper functionality and compliance with electrical standards. Jargons in the Industry: - Ground Resistance: Resistance of the earth electrode or grounding system. Step and Touch Potential: Potential difference between two points on the ground when a fault current flows through the earth. - Ground Fault: Occurs when an electrical current flows through the earth instead of following its intended path, causing electrical shocks, fires, or equipment damage. Maintenance of Earthing Systems: - Inspect and test the earthing system regularly to ensure it is functioning correctly. - Properly install and connect the earth electrode to the electrical system. - Keep the area around the earth electrode clear of debris and vegetation. - Conduct soil resistivity tests periodically to ensure that the grounding resistance remains low #electrical #maintenance #power #safety #electricalengineering #electricalsafety #electricalmaintenance Activate to view larger image,

To calculate the estimated quantity of wiring cable needed for a 32,000 square foot area based on the thumb rule of 1.5 to 2 feet per square foot, you can use the following calculations: Using 1.5 feet per square foot: Total length of wiring cable = 32,000 sqft * 1.5 ft/sqft = 48,000 feet Using 2 feet per square foot: Total length of wiring cable = 32,000 sqft * 2 ft/sqft = 64,000 feet Therefore, based on the thumb rule of 1.5 to 2 feet per square foot, for a 32,000 square foot area: The estimated quantity of wiring cable needed would be approximately 48,000 feet if using 1.5 feet per square foot. The estimated quantity of wiring cable needed would be approximately 64,000 feet if using 2 feet per square foot. These calculations provide a rough estimate of the amount of wiring cable required for electrical installations in a building of 32,000 square feet based on the given thumb rule. It is important to conduct a detailed electrical design and calculation to determine the precise quantity of wiring cable needed for the specific requirements of the building project.
