Frequently Asked Questions

What is the 4 mm² green/yellow cable used for?

This color is standardized exclusively for the grounding or earthing circuit. Its main function is to divert potential leakage currents to the earth to prevent electric shocks to users and protect connected appliances.

What advantages does a halogen-free cable offer compared to a traditional PVC cable?

The main advantage is fire safety. Halogen-free cables do not emit corrosive or acidic gases that could damage lungs or equipment in case of fire, and they also generate much less smoke, improving visibility during a possible evacuation.

Is it easy to install on narrow corrugated pipes?

Yes, thanks to its class 5 flexible wire design and its slip-resistant insulation, it slides easily through the inside of pipes and channels, reducing the effort and time required for connection.

Does this cable comply with current regulations?

Yes, this conductor meets the European and national safety and quality standards required for electrical installations in homes, offices and public venues.
