Husholdningsspænding

Husholdningsspænding refers to the standard voltage supplied to residential buildings for general use. In most of Europe, this is typically 230 volts alternating current (AC) at a frequency of 50 hertz (Hz). North America commonly uses 120 volts AC at 60 Hz, with some appliances and larger equipment utilizing 240 volts. The specific voltage and frequency are determined by the electrical grid infrastructure of a region and are standardized to ensure compatibility with household appliances and electrical devices.

This voltage is considered "low voltage" in electrical engineering terms, making it relatively safe for everyday use when handled correctly. However, direct contact with even household voltages can be dangerous and potentially lethal. Electrical outlets are designed with specific pin configurations and safety features to prevent accidental contact and incorrect appliance insertion.

The purpose of household voltage is to power a wide array of devices, from lighting and small appliances like toasters and hair dryers to larger ones such as refrigerators, washing machines, and ovens. The electrical grid generates power at much higher voltages and then steps it down through transformers to safe and usable levels for distribution to homes. Understanding household voltage is crucial for electrical safety, proper appliance usage, and efficient energy consumption.
