LARSEN & TOUBRO LIMITED L&T House, BaUard Estate, P.O. Box No 278, Mumbai, 400 001, Maharashtra, INDIA THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE NATURE OF THE INVENTION SAFETY SHUTTER SYSTEM FOR ISOLATING LIVE PARTS IN SWITCHING DEVICES A) Technical field [0001] The embodiments herein generally relate to switching devices such as miniature circuit breaker, residual current circuit breaker, and isolator and more particularly it relates to protective shutter for isolating live-parts in switching devices. B) Background [0002] Switching devices such as miniature circuit breakers, residual circuit breakers and isolators generally provide protection against over current and under current and line leakages to the end product. In addition to monitoring current it is also sensitive to heat, so that if there is too much heat in the panel, the breaker will trip. [0003] Direct Contact with switching devices is one of the common hazards identified in the electrical industry. The risks associated with this hazard are significant. In managing risks associated electrical work, preventing electric shocks is a major part of discharging electrical safety obligations. [0004] Some times user needs to operate the switching devices directly, which requires touching the live parts. Technicians can be exposed to the hazards of electric shock, arcing and explosion by direct contact with exposed live parts. Usually the cables of various sizes are used in circuit breakers depending on their rating. So if cable of smaller size is used there is possibility that user may touch terminal, as there will be a blank space below cable it may result in shock to the operator. Especially during installation of switching devices there are chances that user may touch the live parts, it may result in serious shock and can be fatal. Therefore it is very essential that there should be proper protection form these switching devices. [0005] Sometimes the terminal is not completely closed at the time of inserting the cable and because of this user tightens cable below the terminal by tightening the screw in reverse direction, this will results in a serious shock since it is loosely connected. Hence there is a need to prevent the users from direct contact with the live parts. [0006] Hazards normally occurs when the user touches the terminal, when smaller sized cables are inserted into the terminal, as there is a blank space left below the terminal. Electrical shock generally occurs when the body becomes part of the electric circuit, when individual comes in contact with both wires of electrical circuit or a metallic part that has become energized by contact with electrical conductor. Normally, the circuit breaker in a circuit is matched to the wire size. An electrical hazard occurs when the wire is too small then the gauge for the current it will carry. When the operators come in direct contact with the exposed parts without realizing the open contact at the terminals it might result in serious shock. [0007] In general the electrical equipments that are poorly maintained, inappropriately used without any precautions can cause injuries. With electrical work, there is an added risk of electric shock resulting from the direct contact with the cable terminals. In order to overcome these short comings, there is a need to develop an improved shutter to enclose the cable terminals. [0008] Prior art discloses a shutter assembly for electrical terminals which protects exposed terminals preventing accidental contact with individual control devices. It also discloses a shutter mechanism for an enclosed electrical switchboard. None of the existing systems provide a shutter for easy fitment with the terminal and easy assembly to save time and cost with unique shape and configuration. [0009] Hence it is necessary to develop an improved shutter, which is capable of covering an exterior section in such a manner that any gap through which internal terminals are exposed to the exterior is eliminated. Also it is necessary to provide a high degree of protection so that the user would not be able to touch live terminal even when the cable of smaller size is used. It is necessary to develop an improved shutter for fitment of shutter with terminal, with unique shape and configuration and to provide improved assembly leads to save time and cost. C) Object of the invention [0010] An object of the embodiment is to provide an improved shutter, which is capable of covering an exterior section in such a manner that any gap through which internal terminals are exposed to the exterior is eliminated. [0011] Another object of the embodiment is to provide a high degree of protection so that the user would not be able to touch live terminal even when the cable of smaller size is used. [0012] Yet another object of the embodiment is to provide an improved shutter for fitment of shutter with terminal, with unique shape and configuration and to provide improved assembly leads to save time and cost. [0013] Yet another object of the embodiment is to provide a method to deal with wrong insertion of cables in switching devices. D) Summary [0014] The present invention deals with protection against touching live parts and wrong insertion of cables. Cables of various sizes are used depending on rating of circuit breaker. So if cable of smaller size (i.e. for smaller rating) is used, there is possibility that user may touch terminal, as there is blank space below cable. The invention provides high degree of protection in this case i.e. user cant touch live terminal even cable of smaller size is used. During installation of switching devices sometimes unknowingly user puts cable below the terminal when terminal is not fully open and tightens the cable by tightening the screw in reverse direction. The invention also provides method to deal with wrong insertion of cables. [0015] The system consists of a terminal, terminal screw, shutter assembly, a groove and housing. Terminal is characterized by two holes in which the hinges of safety shutter get fit. Safety shutter is characterized by two hinges for fitment with terminal. The purpose of this shutter is to give isolation from live terminal. When terminal is fully closed or semi closed then there is a gap or opening left below terminal, so to avoid this gap safety shutter is provided. Terminal screw is used for tightening the cable in the terminal. The assembly moves when terminal screw is tighten or loosen. [0016] These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating preferred embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications. E) Brief description of the drawings [0017] The embodiments herein will be better understood from the following detailed description with reference to the drawings, in which: [0018] FIG. 1 shows unassembled terminal and safety shutter components. [0019] FIG. 2 shows terminal and safety shutter assembly. [0020] FIG. 3 shows the terminal screw loose and safety shutter resting in housing when there is no cable inserted in terminal. [0021] FIG. 4 shows the terminal screw tight and safety shutter blocking the opening left below the terminal when there is cable inserted in terminal.
