What type of circuit is typically required in bathrooms according to electrical code?

In bathrooms, electrical code typically requires dedicated 20-amp circuits to ensure safety and adequate power for high-demand appliances. The reason for this requirement stems from the need to accommodate the electrical load of devices commonly used in bathrooms, such as hair dryers, electric razors, and other personal grooming appliances, which can draw significant current.

Dedicated circuits are essential to prevent overloads, which can lead to tripped breakers or potential electrical hazards. Furthermore, these circuits must be GFCI (Ground Fault Circuit Interrupter) protected due to the presence of water, which increases the risk of electric shock. By using a dedicated 20-amp circuit, the electrical system can handle the load without putting users at risk, adhering to safety standards set forth in the National Electrical Code.

In contrast, although lighting circuits and standard 120-volt circuits may be suitable for other parts of a home, they do not specifically address the increased load demands typical in a bathroom environment. Specialized circuits with higher amperage ratings, such as 30-amp circuits, are unnecessary and typically reserved for heavy-duty appliances and are thus not applicable in this context.
