When encountering a problem at work, I go to Haichuan to ask the experts what they think. Specifically, the wiring sleeves for the electric valve actuators in the oil depot are made of galvanized steel pipes, and explosion-proof junction boxes are used for connecting them. Is it necessary to make a bridge connection on both sides of the explosion-proof junction box, and what is the purpose of such a bridge connection?
According to the provisions of the \"Code for Acceptance of Construction Quality of Building Electrical Engineering\" GB50303-2002, it is necessary to make connections across electrical conduit; the purpose of such connections is to ensure electrical continuity of the conduit and to guarantee its proper grounding, thereby preventing accidents caused by electric leakage.
Wire conduits need to be bridged; the purpose of this is to ensure electrical continuity of the conduits and to guarantee a reliable grounding of them.
