Outdoor three-proof distribution box installation requirements 1, first outdoor three-proof distribution box installation requirements must be checked before installation. If you do not check, it will be easy to use problems after a period of time. For example, there are no grounding bolts on the second floor board, the wires are not firmly connected, there are anti-circle phenomena, etc. These details will affect the use of the distribution box.
2. The outer shell of the outdoor distribution box and the surface of the metal parts must be flat and free of burrs. The welds should be smooth, uniform, free of welds, cracks, undercuts, splashing slag, pores, etc. The weldment should be clean.
3, the installation of outdoor three anti-distribution box requirements on the spray box can not have wrinkles, flow marks, pinholes, foaming, uneven color and so on. The production process of the distribution box is very complicated, so there are also many details to pay attention to when making the distribution box.
4, wiring should match. Otherwise, the maintenance cable of the distribution box is not arranged out of the terminals, but is connected in series by the box frame. The wire diameter is not set according to the requirements. The device with the ultra-safety voltage of the distribution box door is not equipped with maintenance ground wire, which easily leads to safety accidents.
5 Outdoor three-proof distribution box installation requirements Inside the removable metal plate, with the maintenance of the ground system connection. If the detachable metal plate in the distribution box is equipped with various electrical accessories and does not receive a maintenance ground wire, electric shock accidents may easily occur. It is extremely important to use the distribution box safely.
6 In the installation requirements of the three outdoor anti-distribution boxes, the brake shall indicate the name of the circuit. If mistakes are made in mistakes, accidents can easily occur. There must be a route system diagram attached to the distribution box door, and the name of the circuit should be marked on the brake. In particular, if there are exchange, DC or different levels of power supply in the distribution box, it should have a clear sign. To bring convenience and safety to the use of personnel and maintenance personnel.
7 The installation requirements of the outdoor three-proof switch box are equipped with various electrical accessories inside the detachable metal plate. If the ground wire is not connected, the electric shock accident may easily occur. The removable metal plate in the lighting distribution box should have reliable grounding and maintenance. Therefore, a special non-detachable grounding screw should be installed on the metal plate. The maintenance grounding wire should be connected to it effectively. The wire diameter of the maintenance ground should be required according to the standard to ensure safe use.
8 The floor of the wire pipe laid in the floor-type distribution box is too low, and it is easy for water and debris to enter the pipe and reduce the insulation strength of the wire. Measure: The wire maintenance pipe in the floor-type distribution box should have a nozzle height 50-80mm above the base surface of the distribution box. The pipelines should be arranged neatly and the nozzles should be flared.
9 Outdoor three-proof distribution box installation requirements If the box is used in a humid and dusty place, it is easy to use the wooden mold and electric leakage; the wooden box does not pass the flame retardant treatment, it is easy to cause fire, and it is unsafe hidden trouble. Measures: To ensure safe use, requests for outdoor distribution boxes should not be made of flammable materials. Even in dry and dust-free places, the wooden distribution box used should be flame-retardant before it can be used.
10 Outdoor three-proof distribution box installation requirements The installed elevation is not in compliance with the regulations, the installation is not solid, the box is not vertical, when the concealed installation, the four edges of the panel do not close to the wall, affecting the use of features, the perception is not good. Measure: The elevation shall meet the design request. When the design is not specified, the height of the bottom edge of the outdoor distribution box shall be 1.5m. The height of the bottom edge of the outdoor distribution box should be 1.8m. The installation of outdoor distribution box shall be firm, and the deviation of installation verticality shall not be greater than 3mm. When concealed, there shall be no gaps in the distribution box, and the edges of the four sides of the panel shall be tightly adhered to the wall, and the parts of the box that are in contact with the building or structure shall be painted and protected. paint.

British Fittings are manufactured using British threads such as British Standard Pipe Parallel (BSPP) and British Standard Pipe Tapered (BSPT). These fittings and adapters are commonly found on equipment manufactured in the United Kingdom as well as from some OEM's in Europe.
The BSPT (tapered) male will mate with a BSPT (tapered) female and the BSPP female swivel. The BSPT male has tapered threads and a 30-degree inverted seat.
