Advantages and disadvantages over traditional electrical wiring
Advantage
Source: * Electrically Safe installation up to IP 60 inside the cabinet, * Drastically reduce space required inside the cabinet * Easy trouble shooting in case of switch gear failure * Pre-tested short circuit rating * Mounting of 2, 3, 4 or 5 pole switchgear in a single construction * Time saving during construction of the cabinetDisadvantages
* Commercially not viable if the number of switch gears is low * Specialists needed for construction of the busbar system from a wiring diagram * Lack of adapters for mounting different electrical devices on the busbar * Special type of busbars needed to construct busbar system which can carry current more than 800 AmpereSee also
