Next, let's talk about the internal wiring requirements of the frying machine:

        1. The wiring groove should be smooth and free of sharp edges, otherwise it needs to be protected with a wire sleeve.

        2. The insulation of internal wiring should be able to withstand the electrical stress that may occur during normal use.

        3. When the sleeve is used as an additional insulation for internal wiring, it should be fixed in a reliable manner.

        4. The yellow green dual color wire can only be used as a grounding wire.

        5. Aluminum wire should not be used for internal wiring.

        6. Multi stranded wires cannot be welded where they are subjected to contact pressure, unless there is a clamping device that does not pose a risk of poor contact.
