1. Industrial plugs shall adopt products that have passed the inspection by relevant laws and regulations and product quality supervision units. A switch is arrange between that resistance of the weatherproof socket and the electromagnetic switch; the fuse and the electromagnetic switch are connected with a pow line; the power line is provided with an electromagnetic switch normally open switch which is connected with a jack. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. 2。 Safe power outlets should be used for industrial plugs in homes, and waterproof box power outlets should be used in damp and cold places, such as toilets. 3。 The rated voltage of industrial plugs shall exceed 1.25 times of the rated voltage of known applied machinery and equipment. The rated voltage of general single-phase industrial electrical outlet is 10a, and the special industrial plug 16a. The power supply mode of the control circuit and wiring switch of the unique power and electrical products distribution device should be selected according to the specific volume. 4. In order to connect and plug conveniently, the number of power outlets should be 2, and the maximum number (including power switches) should not exceed 3; 5. For plug-in electrical products with electric shock hazard, the power socket should be closed with the power switch. 6. In relatively wet and cold places, waterproof case shall be additionally installed when installing power sockets. Attention to industrial plug installation: 1. The aspect ratio of industrial plugs shall be installed according to the design requirements. When the design fails, the general requirements are: the power socket with anti-theft door is higher than 0.3m, and the power socket without anti-theft door is lower than 1.8m. It is recommended to purchase the power socket with anti-theft door as much as possible, because the price difference between the two is not big. 2. In restrooms or other wet and cold places, moisture-proof and waterproof case sockets with excellent sealing performance shall be adopted. (Note: The power socket with anti-theft door is a plastic clapboard (anti-theft door) in front of the metal spring piece of the socket. Three hole socket, when the power plug is inserted, the pile head (too long) of the grounding device is inserted into the hole wall first, and the other two hole doors are opened according to the mechanism posture in the power socket. The two-hole power socket must be inserted into the pile head of the power socket separately, and the anti-theft door can be opened, so as to prevent children from mistakenly inserting internal metal objects to cause accidents in production safety. ) 3。 When installing the power outlet, the control panel should be placed vertically near the wall. Wiring (location) shall conform to: single-phase two-hole power socket, right or upper hole phase (live wire zero line) of power socket, and left or lower hole to zero line; Single-phase three-hole power socket, the right hole phase of the power socket (live line and zero line), and the left hole are connected with the zero line (N) and the upper hole wire connector (pe).
