👉 CONDUÍTE entupido na LAJE nunca MAIS: RESOLVIDO! 🙌

Summary

In this video, the host takes viewers through a detailed process of electrical installation on a construction site, specifically focusing on the reconfiguration of old wiring and the installation of new ducts and electrical components. The project involves replacing old, deteriorated wiring, cutting new access points in the ceiling, and ensuring proper connections for various electrical circuits. The host also shares tips for handling common issues in electrical installation, like dealing with outdated components and ensuring safe, reliable setups. The video offers practical advice for electricians and construction workers in the field.

Takeaways

• 😀 Always assess old electrical installations carefully before starting new work, as outdated systems can pose safety risks.
• 😀 If encountering old, dried-out ducts, sometimes the best solution is to remove and replace them rather than trying to salvage them.
• 😀 Upgrading electrical conduits to a larger size (e.g., from 20mm to 25mm or 32mm) ensures better reliability and accommodates modern electrical needs.
• 😀 When working with ceiling-mounted electrical boxes, it’s often necessary to remove covers and adjust them to fit new conduit sizes.
• 😀 Using lighter materials like Styrofoam (expanded polystyrene) can help manage weight on the ceiling when adding new flooring or concrete layers.
• 😀 Always prioritize safety when performing electrical work, and ensure you follow the correct procedures, especially when dealing with conduit connections.
• 😀 Avoiding shortcuts in electrical installations can prevent future problems; always use appropriate fittings and connectors for conduit joints.
• 😀 If you struggle with electrical component identification or configuration, a reliable app or online support tool can help you troubleshoot in real-time.
• 😀 Pay attention to the details when installing electrical systems, as small issues like broken ducts or poorly fitted boxes can cause larger problems later.
• 😀 Stay updated with tools and resources, such as the Chinaider app, to enhance your efficiency and troubleshoot electrical issues on-site.

Q & A

What is the main focus of this video?

The video focuses on the electrical installation process, including the steps for installing new ducts, removing old components, and addressing challenges such as replacing damaged or outdated materials in a construction project.

Why did the creator choose to remove the covers from the octagonal boxes on the ceiling?

The decision was made because the new ducts (25mm) could not fit into the old boxes, which were originally designed for smaller 20mm ducts. Removing the covers allowed for better installation and distribution of the new ducts.

What problems did the team face with the existing ducts?

Many of the existing ducts were severely deteriorated and resed, with some being covered by mass or debris. The ducts were mostly outdated, with sizes incompatible with the new system requirements.

How did the team handle the issue of the existing ducts being too small for the new installation?

In cases where the existing ducts were too small (20mm), the team had to break parts of the ceiling and replace them with new 25mm ducts. They also used 32mm ducts to make necessary connections where required.

What was the solution for the conduit that needed to be routed through a wall?

For the conduit that needed to go through a wall, a hole was drilled from inside to outside, and then a hole was made from the outside to accommodate the new 32mm duct. This method allowed for proper installation without disturbing the structure too much.

What is the reason for using a thicker conduit in some areas, like the 32mm conduit?

The thicker 32mm conduit was used to ensure better connectivity between the components and to accommodate the new system's requirements. The 32mm conduit also provided more flexibility when making connections where the standard 25mm conduit didn't fit.

What issue did the team face regarding electrical connectors and joints?

The team had difficulty finding appropriate connectors for the 25mm ducts. As a workaround, they used 32mm conduit pieces to make connections, even though this is not the ideal solution, due to the difficulty of finding suitable connectors.

How did the construction team address potential weight concerns for the ducts on the ceiling?

The client planned to add a new upper floor and pour a new layer of concrete on top of the ceiling. This would help cover the ducts and relieve any weight concerns by using lightweight material such as slag (a light construction material), which would reduce the load on the ceiling.

What alternative method was suggested for reducing the weight on the ceiling?

One alternative method mentioned was using expanded polystyrene (foam board) under the new concrete layer. This method helps distribute the weight more evenly and reduces the load on the ceiling.

What tool was recommended for troubleshooting electrical issues during installation?

The video introduces an application developed by China, which provides online technical support to assist electricians with troubleshooting and guidance during complex installations or when faced with challenging electrical issues.
