, Description:
TECHNICAL FIELD
[0001] The present disclosure relates to an electrical distribution board, and more specifically relates to, an isolation mechanism or push button/rotary mechanism to make contact with the at least one lateral conductor tab and out of electrical contact with the at least one outgoing conductor terminal for protecting or isolating any circuit with fast and simple adaption.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] An electrical distribution board distributes electrical power from one or more incoming power supply terminals to a number of outgoing power supply terminals. Typically, the electrical distribution board comprises one or more bus conductors which run the length of the board. The bus conductors carry the incoming electrical power to one or more outgoing "stab" conductors which are, in turn, connected to one or more circuit breakers of the outgoing circuit.
[0004] In the case where the bus conductors of the electrical distribution board are connected directly to the stab conductors, when work is required to be carried out on one or more of the outgoing circuits the circuit breakers are used to break the electrical connection between the stab conductors and the outgoing circuit. Then, in order to prevent the circuit breakers from being accidentally reconnected, a plastic cover, which may be lockable, or electrical insulation tape is placed over the circuit breaker switch. Alternatively, and more properly, the circuit breaker is removed from the distribution board and a blanking module is used to cover the stab conductor. Once the work is complete the plastic cover or the tape or blanking module are removed and the outgoing circuit reconnected. The tape technique is not recommended or officially sanctioned, but often happens in practice. In addition to an MCB, or the like, being provided between the stab conductor and the outgoing circuit, the electrical distribution board may additionally include an isolation switch positioned between the bus conductor and the stab conductor. Schneider Electric in particular supplies "Isobar" brand of boards with this feature. The purpose of the isolation switch is to allow unused stab conductors to be electrically isolated from the bus conductor. The isolation switches are located within an insulated housing block which at least partially shrouds the stab conductors, the isolation switches and the bus conductors. The housing block, stab conductors, isolation switches and bus conductors are mounted upon a mounting plate to which the circuit breakers are latched. The mounting plate is secured inside a standard cabinet, or the like. This facility is not designed to prevent electric shock when work is required to be carried out on the outgoing circuit, but is sometimes used by workers for that purpose.
[0005] Efforts have been made in related art to address above stated problem by using an electrical distribution board. An example of such electrical distribution board is recited in; WO2014016604 A1 entitled “Improvements in or relating to electrical distribution boards”. The patent discloses at least one isolation mechanism, which is slide operated switch to make contact with the at least one lateral conductor tab and out of electrical contact with the at least one outgoing conductor terminal. The electrical distribution board comprises at least one incoming conductor terminal, at least one outgoing conductor terminal, at least one longitudinal bus conductor connected to the at least one incoming conductor terminal, at least one lateral conductor tab connected to the at least one bus conductor for distributing electrical power from the at least one bus conductor to the at least one outgoing conductor terminal, and at least one isolation mechanism for electrically isolating the at least one outgoing conductor terminal from the at least one lateral conductor tab. The at least one isolation mechanism is moveable between a first position in which the at least one outgoing conductor terminal is electrically isolated from the at least one lateral conductor tab and a second position in which the at least one outgoing conductor terminal is electrically connected to the at least one lateral conductor tab. The at least one isolation mechanism is configured to be engageable with a housing of the electrical distribution board when the at least one isolation mechanism is in the first position, such that movement of the at least one isolation mechanism from the first position to the second position is only possible once the at least one isolation mechanism has been disengaged from the housing of the electrical distribution board.
[0006] However, in the prior-art PAN assembly in distribution box allows only 1P and 3P outgoing protection and control devices which leads to the loss of pole place in case of 2P and 4P outgoing protection and control devices. In the prior art there is no way by which 1P & 3P outgoing protection and control devices to be installed adjacent to 2P & 4P devices, without the loss of pole places.
[0007] Whereas there is certainly nothing wrong with existing techniques or system, nonetheless, there still exists a need to provide an efficient, effective, reliable and improved isolation mechanism to make contact with the at least one lateral conductor tab and out of electrical contact with the at least one outgoing conductor terminal for protecting or isolating any circuit with fast and simple adaption. Further, there exists a need of a compact design of isolation mechanism with appropriate creep age and clearance through special feature in the housing. Furthermore, there is a need of an effective solution to PAN assembly of distribution board. Additionally, there is a need of a unique busbar disconnection system permits unused outgoing poles to be electrically isolated from the mains supply via a push button / rotary mechanism. Moreover, there is a need of a PAN assembly with an option of converting any of the outgoing poles to a neutral that allows 1P and 3P outgoing protection and control devices to be installed adjacent to 2P and 4P devices, without the loss of pole places. In essence, an innovative switched neutral feature makes it possible to protect or isolate any circuit with fast and simple adaptation.

[00040] The present disclosure relates to an electrical distribution board, and more specifically relates to, an isolation mechanism or push button/rotary mechanism to make contact with the at least one lateral conductor tab and out of electrical contact with the at least one outgoing conductor terminal for protecting or isolating any circuit with fast and simple adaption.
[00041] However, in the prior-art PAN assembly in distribution box allows only 1P and 3P outgoing protection and control devices which leads to the loss of pole place in case of 2P and 4P outgoing protection and control devices. In the prior art there is no way by which 1P and 3P outgoing protection and control devices to be installed adjacent to 2P and 4P devices, without the loss of pole places.
[00042] The present invention provides an isolation mechanism or push button/rotary mechanism to make contact with the at least one lateral conductor tab and out of electrical contact with the at least one outgoing conductor terminal for protecting or isolating any circuit with fast and simple adaption. The proposed invention provides a compact design of isolation mechanism with appropriate creep age and clearance through special feature in the housing. The proposed invention provides a unique busbar disconnection system permits unused outgoing poles to be electrically isolated from the mains supply via a push button / rotary mechanism. The proposed invention provides a PAN assembly with an option of converting any of the outgoing poles to a neutral that allows 1P and 3P outgoing protection and control devices to be installed adjacent to 2P and 4P devices, without the loss of pole places.
[00043] Present invention or prior-art of providing PAN assembly in distribution box allows only 1P and 3P outgoing protection and control devices which leads to the loss of pole place in case of 2P and 4P outgoing protection and control devices.
[00044] The proposed invention describes the new effective solution to PAN assembly of distribution board. This unique Busbar disconnection system permits unused outgoing poles to be electrically isolated from the mains supply via a push button / rotary mechanism.
[00045] The proposed PAN assembly has an option of converting any of the outgoing poles to a neutral. This allows 1P and 3P outgoing protection and control devices to be installed adjacent to 2P and 4P devices, without the loss of pole places. In essence, the innovative switched neutral feature makes it possible to protect or isolate any circuit with fast and simple adaptation.
[00046] The proposed invention describes the new effective solution to PAN assembly of distribution board. The unique Busbar disconnection system permits unused outgoing poles to be electrically isolated from the mains supply via a push button / rotary mechanism. The proposed invention provides enhanced result protection against direct contact with live parts during testing commissioning and retrofit applications.
[00047] According to the present practice there is no way by which 1P and 3P outgoing protection and control devices to be installed adjacent to 2P and 4P devices, without the loss of pole places. An electrical distribution board distributes electrical power from one or more incoming power supply terminals to a number of outgoing power supply terminals. Usually, the electrical distribution board consists of one or more bus conductors, which run the length of the board. The bus conductor carry the incoming electrical power to one or more outgoing connecting links which are, in turn, connected to one or more circuit breakers of the outgoing circuit. In the case where the bus conductors of the electrical distribution board are directly connected to the connecting links, when work is required to be carried out on one or more of the outgoing circuits the circuit breaker are used to break the electrical connection between the outgoing link and circuit breakers. Then in order to prevent the circuit breakers from being accidentally a blanking module is used to cover the connecting conductors. The present invention of PAN assembly has an option of plug, which can be used to convert any of the outgoing poles to a neutral. This allows 1P and 3P outgoing protection and control devices, without the loss of pole places. In short, the present innovation makes it possible to protect or isolate any circuit with fast and simple adaption.
