1. The elevation or verticality of the distribution box (panel) exceeds the allowable deviation: it is caused by inaccurate measurement and positioning or uneven ground, and should be corrected in time.
2. The iron frame of the distribution box is not square: if the iron frame is not straightened and aligned before the installation, or the position of the fixed point is offset during installation, the hanging wire should be re-aligned and then fixed.
3. The electrical appliances and instruments on the distribution box are not firm, flat or unevenly spaced, the pressure head is not firm, the pressure head hurts the wire core, and the multi-strand wire pressure head is not equipped with a crimping wire terminal. The card frame is not installed under the gate, and the screws should be tightened if they are not tight, and the spacing should be adjusted evenly and leveled as required. The part of the injured wire core should be cut off and reconnected, the multi-strand wire should be equipped with crimping terminals, and the card frame should be reinstalled.
4. The cross-section of the grounding wire is not enough or the cross-section of the protective ground wire is insufficient, and the protective ground wire is connected in series, and these non-conforming requirements shall be corrected in accordance with the relevant regulations. The PE wire terminals in the distribution box and panel are suitable for general public construction projects, and are not suitable for civil residential projects.
5. The wiring arrangement behind the disc is not neat: it should be tied into a bundle according to the branch and fixed in the disc.
6. Missing parts of the distribution box (panel), such as hinges, locks, screws, etc.: all kinds of parts required for installation should be complete.
7. Long holes for electric and gas welding of iron boxes: one pipe and one hole should be opened, no electric and gas welding holes should be opened, and the box should be flush.
8. The gap around the stable construction of the distribution box is too large: the box and pipe should be built with cement mortar: firm.
9. There is no anti-corrosion on the outside of the wooden box, and the inner wall is rough: it should be treated according to the regulations.
10. Rust of the inner wall of the iron box of the distribution box: anti-rust paint should be repaired.
