What is the method of attaching a pothead to the sheath of a cable?

The method of attaching a pothead to the sheath of a cable is commonly done using a wiped joint or a clamping joint. A wiped joint involves the process of melting and fusing materials together, which provides a strong, durable connection that is also weather-resistant. This method is particularly useful when ensuring that there is no gap between the pothead fitting and the cable sheath, which is critical for both functionality and safety.

A clamping joint, on the other hand, secures the pothead by physically squeezing it against the cable sheath, using mechanical force to create a solid contact point. This type of joint is reliable and allows for easier disconnection and reconnection of parts if maintenance is required.

These methods are favored in electrical work for their effectiveness in ensuring a good electrical connection and mechanical integrity, which is essential for the performance and longevity of the electrical system. Other options listed do not align with the common practices used for connecting potheads specifically to cable sheaths, as they pertain to different types of electrical or mechanical joints not typically used in this context.
