Definitions

  • the present invention relates to a distribution board in which is mounted a plurality of circuit breakers, and in particular to a split load distribution load.
  • Distribution boards are also known as circuit breaker panels, fuse boxes or consumer units. They are generally found in central locations within buildings and often serve as the point at which electricity is distributed to a plurality of downstream circuits within a building from an upstream cable supplying electricity into the building. Distribution boards generally house a plurality of electrical circuit breakers, each of which connects the upstream cable to a downstream circuit. Circuit breakers are automatically and manually automated switches designed to automatically disconnect so as to protect a downstream electrical circuit from damage caused by an overload and/or a short circuit. The circuit breakers can then be re-connected manually, generally by flicking a manual switch actuator.
  • Distribution boards and their associated circuit breakers are made in varying sizes and capacities, ranging from those used in domestic households to those used in industrial applications.
  • a common form of circuit breaker used in domestic applications is a miniature circuit breaker or MCB.
  • Distribution boards generally include an isolator switch between the upstream cable and all of the circuit breakers of the distribution board. This enables the supply of electricity to the distribution board to be interrupted, for example, during maintenance of the distribution board.
  • RCD residual current device
  • An RCD is generally required in addition to the circuit breakers and so is typically wired into the distribution board between the isolator switch and one or more circuit breakers.
  • RCD only some of the downstream circuits require connection via an RCD, for example to circuits supplying appliances in an environment including water, such as outdoor areas, bathrooms, kitchens, swimming pools, etc.
  • Distribution boards in which some circuits are connected via an RCD and some are not are known as split load distribution boards. If all of the downstream circuits are connected to the upstream supply cable via an RCD then any electrical fault will cause power to be cut to the entire building, including lighting circuits, freezers and fire alarms. Before wiring such known distribution boxes, it is necessary to decide which downstream circuits require RCD protection because subsequent re-wiring of the distribution board is a costly and time consuming process. This can become a problem, for example, if a building is extended or parts of the building change their use from or to an environment including water. Most currently used distribution boards comprise circuit breakers that are wired directly to the downstream circuits. Also, the live and neutral wires of the supply cable are directly wired into the isolator switch.
  • Distribution boards are advantageously designed with a degree of flexibility, so that for different buildings, different downstream circuits can be connected to the supply cable via an RCD and so that over time changes of use of buildings can be accommodated in the distribution board.
  • a first aspect of the present invention aims to overcome at least some of the problems set out above by providing a split load distribution box, comprising a plurality of components including at least one circuit breaker, an isolator switch, a residual current device, an input for connection within an upstream supply circuit and at least one output for connection within an associated downstream circuit, and additionally comprising a multi-layered bus bar assembly including a stack of substantially planar bus bars pre-configured to make connections between the components.
  • the bus bar assembly improves ease of assembly in a pre-configured distribution box and enables a compact design in which mis-connection of components within the distribution box is avoided.
  • the distribution board according to the present invention can be fitted and wired in a fraction of the time it takes to wire a conventional distribution board. When installing a distribution box according to the present invention, there is no need to cut bus bars to shape. In addition, inspection and fault finding is improved, when compared to a conventional distribution board.
  • the stack may include a substantially planar live bus bar configured to make live connections between the components and a substantially planar neutral bus bar configured to make neutral connections between the components.
  • a third substantially planar earth bus bar configured to make earth connections between the input and output may be included in the stack.
  • each bus bar may be coated with an insulating layer.
  • the coated bus bars may be stacked within an inner housing of the distribution box to form the multi- layered bus bar assembly.
  • each bus bar may be embedded within an insulating plate or layer and the insulating plates or layers may be stacked to form the multi-layered bus bar assembly.
  • the multi-layered bus bar assembly may comprise a stack of bus bars interspersed by insulating plates or layers.
  • the circuit breakers are arranged, optionally with the isolator switch and/or the RCD, in at least one block.
  • the or each block may include socket blocks into which circuit breakers can be plugged so as to enable interchangeable plug in miniature circuit breakers (MCBs) to be positioned as desired.
  • MMBs miniature circuit breakers
  • the whole or part of the multi-layered bus bar assembly may be shaped to fit beneath the or each block and may be suitably shaped to fit beneath the or each block. Then the bus bar assembly, including pre-configured bus bars, can be fitted beneath the block so as to correctly position terminations of the bus bars in relation to the components of the distribution box.
  • the multi-layered bus bar assembly may comprise a single stack of bus bars.
  • the input may comprise a pair of connectors, such as a pair of terminal blocks
  • the output may comprises at least one pair of connectors, such as a pair of terminal blocks and the multi-layered bus bar assembly may be conveniently configured to at least partially house the connectors.
  • Each terminal block houses the live, neutral and earth connection for either an input supply or a downstream circuit, thus further simplifying the wiring as compared to a conventional distribution board as the live, neutral and earth are housed together ergonomically and there is no need to feed individual wires around. With the present invention there is no time consuming need to shape wires for neatness and a professional finish is easier to achieve.

  • Each of the terminal blocks (10, 12) comprises an inner (10', 12') and an outer (10", 12") live, neutral and earth terminal. These terminals are colour coded, for example blue for neutral, brown for live and green and yellow for earth.
