After the screw is tightened, two to five threads of the nut should be exposed, and no more than eight threads should be exposed.
There should be a certain distance between installed parts and heating equipment (consider insulation measures if necessary). In the layout of components or wiring, a certain safe distance should be kept between live conductors with different polarity exposed to prevent short circuit accidents (insulation treatment should be added if necessary).
The insulation wire of the main circuit is usually black, and the ground protection is yellow and green. When connecting cables, do not use vice or needle-nose pliers to straighten the wires. The cables should be straightened with gloves. Do not squeeze the cable bundle into the cable trough by force with a screwdriver or needle-nose pliers.
