How to choose the right cables and plugs for the electrical installation?

Cables and plugs for electrical installation. Selection of appropriate selection is crucial for safety and proper operation of the system. Regardless of whether you are making a new installation or modernizing the existing one, you must take into account several basic factors, such as the type of load, environmental conditions and legal provisions.

Types of electric cables

1. Single -core and multi -core cables

• Single -bollards are mainly used in internal installations, e.g. for connecting sockets or lighting.
• Multiple are used in more demanding installations, e.g. for powering machines or devices requiring several signal cables.

2. Copper or aluminum cables?

• Copper are better in terms of conductivity and flexibility, which is why they are standard in home installations.
• Aluminum are cheaper, but less durable and require a larger cross -section, which is why they are mainly used in industrial installations.

3. Cixture of the cable and current load

The cross -section of the cable is selected based on the maximum current:

• 1.5 mm² - lighting (up to 10 A)
• 2.5 mm² - electrical sockets (up to 16 A)
• 4 mm² - higher power devices, e.g. electric kitchen (up to 25 A)
• 6 mm² and more - main connection, electric heating, engines

Selection of the right plugs

1. Standard plugs for home use

• Schuko plugs (CEE 7/4) - most often used in Europe, with grounding.
• French plugs (CEE 7/5) - used in Poland, have a grounding pain.

2. Industrial plugs

• CEE plugs (so -called force) - used for three -phase devices, e.g. machines or electric stoves.
• Hermetic plugs - intended for installation in moist and pollinated conditions.

What to look for when choosing?

1. Voltage and current - make sure that the wires and plugs have the appropriate parameters to support your installation.
2. Resistance to environmental conditions - use moisture resistant and UV resistant to external installations.
3. Compliance with standards -choose products in accordance with PN-IEC standards, which guarantees their quality and safety.

Summary

Cables and plugs for electrical installations Selection requires analysis of the power of receivers, the working environment and applicable standards. The correct matching of these elements will ensure the reliability and safety of the entire installation.
