It is composed of an assembly of panels. Information is provided based on the best of knowledge and belief and in the spirit of sharing information as a starting point in the study of a complex subject. Study specialized technical articles and papers. While switchboards are design in mind to be means of distribution to the rest of the branches of the circuits. One of the major differences between switchboards and switchgear is the type of breakers that are used. To understand where each fits, we will have a look at their functions and differences. These are often seen in small- and medium-size commercial or institutional facilities. No, it can be either, its how its configured and tested for its application that counts – not merely the title. "Switchgear" (SWG) and "Switchboards" (SWB) (two different things) are for power distribution, meaning they take in primary or secondary voltages at a site and distribute it to other equipment. What is the difference between switch gear and control gear ?.. But, it also illustrates the need for adding dates to the articles published in E-E-P. The electrical distribution equipment is designed to redirect and control the flow of electricity from one or multiple sources, to several different sections or loads. These devices are used to switch the electric power on and off for transformers, motors, generators, transmission lines, and power networks in homes, commercial, industrial, transmission and distribution systems. We make the distinction between switchgear and switchboards meaning one has controls and breakers or contactors, whereas switchboards only have controls and there's no power distribution. IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The choice of using either switchgear or switchboard must be based on many different criteria and the design of the power system requires thought be given to each one. For example, due to the functions and high power handling capacity in switchgears, they use devices such as high power rated circuit breakers. Suggestion Differences between switchgears and switchboards. I agree with the comment given by Jacques Schonek. What is the difference between a switchboard and a panelboard? Individually mounted switchboards can cost between 15 and 50% more than group mounted switchboards, depending on the number and type of devices required. More details. The Difference Between Switchgear and Switchboard Understanding switchgears. The switchgears are classified according to the voltage levels involved in the circuit of application. In such a discussion, it could be useful to start from the official definition given by IEC: Switchboard: part of a manual or manually supervised exchange at which the interconnection of circuits is manually controlled, Switchgear: a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures, intended in principle for use in connection with generation, transmission, distribution and conversion of electric energy. Switchboards require less room as they work primarily through front access. Switchboards and panelboards provide a similar functionality in a power distribution system. Switchboards take incoming power and distribute it to smaller loads. Switchgear - usually a bank of remote operated breakers and contactors. Once the currents are divided, they are then distributed according to the load i.e. I am familiar with both European and North American, and when i see Switchgear, Switchboards etc, I read in context.
