5, wire into the casing, wire fixing tools should be used, first fixed on the wall and inside the wall, and then plaster hidden.

6. It is forbidden to directly lay the conduit under the composite plate. At this point, we haven't done a good job at present, and we will communicate with our customers in the future. The composite floor must be slotted. The conduit under the solid wood floor must be reinforced.

7. It is forbidden to lay the catheter in the kitchen and bathroom floor to prevent water from infiltrating into the catheter. There must be no conduit on the floor of the bathroom, which must be strengthened.

8. The wires passing through the conduit shall not be greater than 40% of the hole area of the conduit, and the wires in the conduit shall not have joints. It is forbidden to mix wires with different purposes in one conduit.

9. When the wire enters the box, make sure it has a certain length, which is 10 ~ 15cm, and the audio is 100cm. When installing and maintaining switches and sockets, please put on hoses.

10. The distance between the water filling pipe and the wall should be 1.5cm, and the left side is hot and the right side is cold, and the distance is 15cm.

1 1. The parallel distance between wires and water pipes should not be less than 30cm, and the crossing distance should not be less than 10cm.

12, there can be no joint between wire points, and the hidden wires in the ceiling must be protected with flame retardant pipes.
