This process is also known as cold ironing. For example to prevent access to the inside of an electric kiln while it is operating a trapped key system may be used to interlock a disconnecting switch and the kiln door. Key interlocks avoid the limitations of electrical interlocking and the restrictions of mechanical interlocking by making use of easily portable keys carried in sequence from one interlock to the next. Using kirk interlocks when connecting ship s power cables to on shore power will ensure that the cables are properly coupled to the junction box before energizing.

With the interlocks arranged as shown only one key is required in the interlocking system.
