Electric Box/Electric Cabinets/Control Cabinets
An electrical cabinet or an electric control cabinet is a cabinet for inserting electrical control devices that supply electricity to various power sources. They are used in residences, school buildings, workplaces, including medium to large industries. The main features are to help prevent electricity accidents thet could result in danger. Electrical cabinet or electrical control cabinet come in different designs and sizes. Users should choose to suit the number of control devices, installation area size and working environment to provide the most effective protection against electric accidents.Junction box, electric control box A switch box or an electrical panel is a group of devices used for inserting fuses, circuit breakers, wires or switches. The product are used in residential and commercial buildings to industrial factories. Usually installed in a single row which has the ability to prevent problems and accidents that may occur in the electrical system, such as a leakage or short circuit etc. There are many styles and sizes to choose from, including plastic boxes, steel boxes, aluminum boxes, stainless steel boxes, waterproof and dustproof type boxes etc. Therefore, you should choose the type and size of the box that suits the size of electrical circuit and installation area for effective protection and enhancement of safety in the use of electrical systems.
Question: What is the function of the electric box?
Answer: An electrical box is a protective component for the safety of electrical appliances. The electric box has 2 main functions: 1) To protect the electrical circuit and electrical equipment from the operating environment, Such as preventing foreign substances such as water and dust from harming the device protection level is identified by IP (Ingress Protection) code. 2) Prevent electrical current at the circuit board leaked to the outside for the safety of operators.
Question: How many types of electrical boxes are there?
Answer: The industrial electrical box can be divided according to usage into 3 main types.
1) Control boxes are used to contain circuit boards and equipment that controls machines such as PLCs, relays, controllers, I/O units, etc.
2) Switch box is a box that will have a switch installed. They are typically small and suitable for use as auxiliary pendants to control the machine. In case, the operator has to control far away from the main control panel.
3) Junction boxes are used for isolating electrical circuits or resting electrical circuits. Moreover, it's easy to maintain or repair electrical circuits.
Question: How to choose an electrical box?
Answer: To choose an electrical box, you should beware of the following factors.
1) Box size: Consider the internal area of the electrical box. They should have enough space for installing various devices. Also, have to consider including the operating space and the direction of the wiring. If we choose a box that is too small, In addition to being difficult to operate, it also results in more difficult cooling.
2) Operating environment: It will directly affect the durability and safety of use, such as for use inside or outside the building. How much dust and water is there and how much electricity it can withstand, etc. Waterproofing is also an important consideration, especially if the electric box will be exposed to moisture or other environmental hazards. Look for boxes with an IP rating that meets your needs; the higher the IP rating, the more protected the box will be against water and other contaminants.
