Summary of “Бесплатный курс по электромонтажу” (Free Course on Electrical Installation)

Main Ideas and Concepts

This extensive video course provides a comprehensive, practical guide to electrical installation, focusing on both apartments and private houses. It emphasizes correct planning, tool usage, installation techniques, and common mistakes to avoid. The course is designed as a free resource, leveraging professional experience from design, engineering, and installation projects across Russia.

Key Lessons and Methodologies

1. Course Introduction and Philosophy

The course is free to help viewers develop skills beyond paid content.
Emphasis on practical, “do it this way, not that way” advice.
Focus on often overlooked topics like markup, switch/socket placement, and groove cutting.
Collaboration with a specialist, Dima Kraev, a top engineering fitter from Krasnodar.
Detailed explanations of installation nuances, including corrugated pipe use.

2. Comparing Electrical Installation in Apartments vs. Private Houses

Private houses have more complex engineering systems (swimming pools, saunas, ventilation).
Renovation in private houses requires different planning and coordination.
Importance of integrating all engineering systems harmoniously.

3. Planning and Layout

Start with a project before any construction or installation.
Planning decisions must precede demolition or partition erection.
Correct door openings, flanging, and switch placement are critical.
Marking and measurements should be done after plastering for accuracy.
Use tablets for digital drawings and project management on-site.

4. Wall and Surface Preparation

Check plaster quality with a rule to avoid future cracks and unevenness.
Proper priming (especially on gas blocks) is essential to prevent plaster cracking.
Recommends dismantling and redoing partitions if the layout is poor.

5. Lighting for Installation Work

Use powerful temporary lighting (spotlights, floodlights, headlamps).
Different types of lighting setups explained (pistol flashlights, tripods, Bluetooth-controlled lights).
Headlamps are essential for precise work in dark or confined spaces.

6. Tools for Markup and Measurement

Laser axis builders (professional vs. Chinese models) compared.
Importance of checking and calibrating levels and laser tools regularly.
Use of folding tape measures, automatic pencils, and metal pencils for durable markings.
Markings should be clear, consistent, and placed in protected areas (corners, doorways).

7. Workplace Organization

Use storage systems (baskets, toolboxes) for tools and peripherals.
Platforms and movable workbenches improve ergonomics.
Use knee pads or tiler’s saddles for comfort during low work.

8. Drilling and Dust Removal

Use hammer drills with dust removal systems to maintain clean workspaces.
Different drill bits and crowns (70 mm preferred for socket boxes) explained.
Cordless and corded vacuum cleaners compared; importance of battery compatibility emphasized.
Safety rules: disconnect tools when changing accessories.

9. Wall Chasers (Grooving Tools)

Cordless wall chasers are practical and efficient.
Cut grooves from top to bottom (physics of easier cutting).
Use thin grooves for easier cleaning and faster work.
Use diamond cutting discs for various materials.
Proper dust removal and vacuum cleaner integration are crucial.

10. Electrical Wiring and Cable Types

Use cables with low smoke and low toxicity (VVG NL LS).
Corrugated pipes provide protection and fire safety.
Corrugation types: heavy and light, PVC and HDPE; color coding for different uses.
Proper cutting and handling of corrugated pipes with specialized tools.
Cable stripping tools and knives (Knipix brand recommended) for safe and effective insulation removal.

11. Installation Techniques

Correct placement and fastening of socket boxes.
Use deep socket boxes for soft materials; shallow ones for reinforced concrete.
Avoid making grooves in the middle of walls; keep grooves close to edges.
Use clips and ties to secure cables and corrugations properly, especially at corners.
Avoid overlapping cables unnecessarily; use distribution boxes for overlaps.

12. Direct Mounting Technique

Use mounting guns (battery and gas-powered) for fast installation.
Comparison of DeWalt and Chinese mounting guns.
Importance of using appropriate clips and fasteners for direct mounting.
Proper spacing of clips near corners to avoid damage.

13. Connections and Terminations

Use crimping cartridges for reliable connections.
Proper twisting and welding techniques for wire connections.
Use hydraulic or mechanical crimping tools for efficiency.
Follow safety rules when welding (eye protection, correct polarity).
Avoid soldering grounds; tinning is acceptable for some connections.

14. Project Management and Communication

Importance of clear communication between client and installer.
Use digital tools and drawings to avoid misunderstandings.
Always verify project details on-site and adjust as necessary.
Mark all wiring and installation points clearly to avoid confusion.

Detailed Methodology and Instructions

Planning Phase

Start with project design before demolition or installation.
Decide door openings and switch placements early.
Use flanging around doors for baseboard installation.
After plastering, take precise measurements for markup.

Markup and Measurement

Use laser axis builders for horizontal and vertical alignment.
Calibrate laser tools regularly.
Use folding tape measures and durable pencils for markings.
Mark corners and doorways to preserve markings.

Tool Usage

Use appropriate hammer drills and crowns (preferably 72 mm for sockets).
Employ dust removal systems connected to vacuum cleaners.
Choose cordless or corded tools based on work conditions.
Use wall chasers top-down for groove cutting.
Change diamond discs regularly for efficient cutting.

Cable and Corrugation Handling

Use corrugated pipes for protection, especially in wooden houses.
Use heavy PVC corrugation for floor areas; light for ceilings.
Cut corrugations with specialized pipe cutters or knives.
Secure clips near corners and at regular intervals.
Use cable ties to bundle wires neatly.

Installation

Install socket boxes with proper depth and spacing.
Keep grooves close to edges, not in the center.
Use direct mounting guns with appropriate clips.
Avoid cable overlaps; use distribution boxes where necessary.
Connect wires using crimp cartridges or proper twisting and welding.

Safety and Ergonomics

Wear eye protection and respirators during dust-generating work.
Use knee pads or tiler’s saddles for comfort.
Disconnect power tools when changing accessories.
Maintain clean workspaces with vacuum systems.

Project and Client Communication

Maintain clear, documented communication with clients.
Use digital tools for project drawings and on-site adjustments.
Confirm all markings and plans before starting work.
