Does it matter if the line is broken?

The joint connection is firm and reliable, the insulation protection is done well, and there will be no natural phenomenon of short circuit. What worries me most is the small decoration shop. Inexperienced young superfine products, weak safety awareness, sloppy wiring, routing and protection work will bury natural hidden dangers of vehicles. If the landlord is not at ease. Then pay a little attention. In summer and winter, it is best to check the joints.
