Summary of "علائمی که در نقشه کشی برق ساختمان جهت برقکاری در آلمان باید بدانیم.!🤔"
Overview
This is a concise tutorial guide to the most commonly used electrical symbols in building electrical diagrams in Germany. It is aimed at electricians, planners, and students learning to read or draw wiring plans. The presenter explains each symbol’s meaning, common variants and practical placement/installation notes.
Purpose
- Understand electrical symbols so you can read and draw installation plans.
- Learn practical hints about where to run cables and how symbols indicate mounting location (ceiling, wall, floor, false ceiling).
- Be aware that many symbols have equivalent variants; confirm the project standard or client requirement before finalizing drawings.
Lines / Cable routing symbols
- Continuous line — ceiling-mounted wiring.
- Distinct symbols indicate:
- Floor/ground runs
- Wall runs
- False-ceiling runs
Lamps and indicator lights
- General lamp symbols.
- Recessed / built-in ceiling lamps.
- Wall lamps.
- Signal / indicator lamps (small warning lamps often mounted on switches or appliances).
- Lamp-in-chassis (lamp inside a switch/chassis) vs chassis shown without a lamp.
Switches and switch variants
- Single-pole switches.
- Single-bridge and two-bridge (double) switches.
- Three-bridge and cross-switch types.
- Two-position selector switches and multi-bridge options.
- Note: Some symbols represent equivalent variants — either may be used on plans if permitted by project rules.
Blinds / Roller-shutter controls
- Electric blinds/shutters with arrows indicating:
- Up / down movement
- Forward / backward for horizontal curtains
Sensors and dimmers
- Symbols/abbreviations for light sensors.
- Symbols/abbreviations for dimmers.
Sockets / Outlets
- Normal single outlet.
- Multi-socket blocks (for example, three-socket groups).
- Combination symbols:
- Socket + switch
- Switch + socket combinations
- Chassis + outlet combos
- Separated-sockets symbol to indicate outlets spaced apart (not joined).
Common appliances and their symbols
- Extractor fan / kitchen fan; backup fan.
- Cooker / electric stove.
- Microwave oven.
- Single-stage water heater (kitchen).
- Washing machine and washer/dryer combinations.
- Dishwasher.
- Practical installation note: In German practice, washing machines are often located in storage rooms or shared laundry rooms rather than kitchens. Communal laundry rooms may use shared, lockable/keyable sockets assigned to each unit.
Heating and HVAC
- Radiator and other heating-element symbols.
- Combined heating/cooling (air conditioning) systems.
- Refrigerator and freezer symbols/abbreviations.
Lighting fixture families (examples)
- Ceiling-mounted lamp (general ceiling fixture).
- Recessed ceiling lamp.
- Wall lamp.
- Mirror cabinet with integrated socket.
- Long/strip luminaires (fluorescent / LED cornice-style fixtures).
Communication and AV outlets
- Telephone and cordless-phone sockets, fax.
- Internet / data outlet.
- Radio / TV outlet.
- Multimedia outlet (TV + radio + internet combined).
- Speaker / loudspeaker and amplifier symbols.
Door entry, intercom and bell
- Internal and external door intercom panel symbols (audio and video).
- Bell (Kling) symbol.
- Door opener / lock actuator (electric strike) symbol.
Grounding / Earthing symbols
- General earth / ground symbol.
- Grounding conductor / bus symbols.
- Grounding point symbols showing connection to equipment, gas/water pipes or building services.
- Earth-protection and earth-line symbols.
Practical notes and cautions
- The presenter points out recommended cable pull locations for kitchen appliances, fans and stoves.
- Verify conductor sizing and dedicated circuits against local codes (an auto-generated subtitle referenced “two and a half” — likely a transcription error; always confirm correct conductor sizes and protections with applicable regulations).
- The video repeatedly shows symbol variants — check project standards or client requirements to pick the correct variant.
Format of the content
- Tutorial / walkthrough style with images of symbols and spoken explanations.
- Encourages viewer interaction (like, comment) and corrections for mispronounced or mistyped terms.
Main speaker / source
- Rat — presenter on the De Tech channel.
