Clause 3 – How to understand the definition of “type Z attachment”
type Z attachment: method of attachment of the supply cord such that any replacement is intended to be made by the manufacturer, its service agent or similar qualified person.
The supply cord of some products is molded together with the product and cannot be removed by common tools. Or the power cord of some appliances is cast onto the appliance by some thermosetting materials after connection. These similar structures require the destruction of the materials connected to the supply cord to complete the action of replacing the supply cord.
Example: As shown in the figure, the supply cord is cast into the shell of the submersible pump by epoxy resin. If the supply cord is to be replaced, the cast epoxy resin must be destroyed.
