Can you plug C15 into C14?


In the world of electronic devices and power connections, understanding the compatibility between different types of plugs is crucial. One such common question is whether it is possible to plug a C15 connector into a C14 socket. In this article, we will explore the technical aspects of these connectors, their differences, and potential implications of using one with the other.

The C15 and C14 Connectors

The C15 and C14 connectors are commonly used in electrical systems, especially for high-power applications. The C14 connector is a male plug with three pins, while the C15 connector is a female socket with three corresponding holes. These connectors are typically used for connecting power cables to equipment such as servers, data centers, and industrial machinery.

The main difference between the C15 and C14 connectors lies in the maximum temperature they can withstand. The C14 connector is designed for operating temperatures up to 70°C, making it suitable for most applications. On the other hand, the C15 connector is built to handle higher temperatures, up to 120°C. This increased tolerance makes the C15 connector more suited for power-hungry devices that generate significant heat.

Compatibility and Considerations

As the physical dimensions of both connectors are identical, it is technically possible to plug a C15 connector into a C14 socket. However, there are important considerations to keep in mind before doing so. The primary factor is the operating temperature of the equipment being connected. If the equipment generates excessive heat and requires a C15 connector, attempting to use a C14 socket may result in damage or even fire hazards.

Additionally, it's crucial to verify the electrical specifications of both the C14 socket and the equipment. While the pins of both connectors fit, using an incompatible connector may lead to electrical problems, inefficient power transmission, or even equipment failure. It is advisable to consult the manufacturer's guidelines or seek professional advice before attempting to use a C15 connector with a C14 socket.


In conclusion, although it is physically possible to plug a C15 connector into a C14 socket, it is important to consider the compatibility and safety implications before doing so. Understanding the differences in temperature tolerance and electrical specifications between the two connectors is vital for safe and efficient operation of electrical equipment. When in doubt, consult experts or follow manufacturer's recommendations to avoid any potential damage or hazards.
