[question]
Why is it risky to regularly charge the car from a wall socket?
[/question]
[answer]
Household outlets are not designed for sustained, heavy loads. Charging a car draws a high current for hours; the socket and the wiring in the wall can heat up, the contacts can loosen, the material can discolor or melt, and in the worst case a fire can start. Faults caused by overloaded outlets are a common issue in electricians' work. A wall socket: at most a temporary, rare emergency solution.

Typical warning signs: a heating outlet, a smell of burnt plastic, a melted plug, a charred terminal block, a softened cable sheath. Don't “wait it out”: stop the charging and have it inspected by a professional.

[question]
Why is a wall charger safer?
[/question]
[answer]
A wall charger is designed specifically for EV charging. It's installed on a dedicated circuit with properly sized cabling and protection, and the device continuously monitors temperature, leakage current, and voltage fluctuations. In case of a fault, it shuts off, preventing overheating and short circuits.

[question]
What protections are needed for a safe installation?
[/question]
[answer]
A dedicated circuit, properly sized cable cross-section, a circuit breaker, an RCD of the appropriate type for EV charging, surge protection, and, outdoors, adequate IP protection rating. The installer takes care of all this.

[question]
Why is it important to have your own home AC wall charger?
[/question]
[answer]
Because it's significantly cheaper and more convenient: the price of home electricity is typically about 25% of the rate at public DC fast chargers. It's also convenient — no need to visit charging stations, and the car is ready by morning.

[question]
Can I use an extension cord or cable reel?
[/question]
[answer]
Not recommended. Extension cords and coiled cables on a reel overheat very quickly and introduce additional failure points into the system. Only charge your car from a properly installed, fixed circuit.
