Definitions

  • the invention is a new type of electrical wiring accessory that provides early completion of the wiring within a building to allow full testing of the system by using a plug-in accessory. It also provides an adaptability that permits easy interchangability of outlets to suit differing national standards and outlet types.
  • the cables once installed are left loose or wound up in the accessory box where they are subject to damage.
  • the accessory box is often filled with cement or plaster as the wall finishes are applied.
  • the cables In order to test and commission the wiring system the cables have to be terminated which means the accessories and luminaires have to be installed. This makes the testing of the complete lighting circuit very difficult; either the lamps are removed or, in the case of fluorescent luminaires, the lamp circuits are disconnected or, as normally happens the light switches are in the "off position. With the light switches off. the phase conductors to the luminaires, i.e. the switch lines, are not tested! Due to the testing and commissioning of the wiring system, the accessories themselves are normally installed before the final painting of walls. This often leads to the accessory being 'painted' along with the walls, sometimes requiring the accessory to be replaced or at the very least needing extensive cleaning. Some contractors try to cover the accessory with a tape to avoid the paint damage, but this is time consuming and not very successful.
  • the plug-in electrical accessory (the Invention) has been developed to overcome these problems.
  • the invention is an accessory box with a plug-in accessory plate for use on a conventional conduit system that overcomes all the problems noted in the background to the Invention and noted below.
  • This device is a complete suite of electrical accessories that allows the wiring system within a building to be fully wired, connected and tested at an early stage in the construction.
  • the cables have to be terminated which means the accessories and luminaires have to be installed.
  • the invention overcomes this by allowing all the circuit conductors to be installed and terminated without connecting the luminaires or the accessories, thus full testing can be carried out.
  • the accessory comprises three basic parts : a) the accessory box (Fig 3)which is installed with the conventional conduit system b) the accessory itself (Fig 6) which is a socket/outlet/receptacle, lighting switch, etc. c) a temporary cover plate (Fig 8) which can be replaced with a maintenance cover plate.
  • the accessory box provides permanent termination of the wiring with plug-in facilities for the accessory.
  • the accessory which could be socket outlet, lighting switch, ceiling rose, or whatever, plugs into the accessory box providing connection to the external circuit. Upon completion of the room finishes, the accessory is simply plugged into the accessory box and is ready for use without any further installation required.
  • a maintenance cover plate (a plug-in lighting switch bypass) can be installed. This would be similar to the temporary cover plate and would inter-connect the wiring to keep the lighting on for as long as the device is in place. With 2-way and intermediate switching, removing one of the 2-way or intermediate switches would not affect the operation of the other, so there would be no need to by-pass the switch. If for any reason the accessory type, i.e. American pattern accessories, are required to be changed for say German pattern, it is only necessary to unplug one device and replace it with the other.
  • the accessory range would cover all devices required within a building and would fully comply with national and international standards.
  • the accessory box is a moulded plastic box (1) arranged to connect to a standard conduit system (2) using a male bushing into a conduit coupler (3).
  • the external sides of the box are flanged (4) to link another accessory box onto any of the four sides.
  • This allows accessory boxes to be joined together to form multi-ganged arrangements up to any number in a matrix form.
  • the flanges ensure that the alignment and spacing of a group of accessories is accurate and consistent.
  • Fig. 5 shows typical elevations of the accessory box.
  • flanges are used to provide fixation when the boxes are recessed into a block or concrete wall. They also act as 'wings' behind plasterboard in a dry partition to prevent the box pulling through.
  • the box would have fixing holes (5) in the base, set to allow for minor re-alignment.
  • Conduit entries are provided on each side; two on the top and bottom side (6) and one on the other two sides (7).
  • Each box when joined to others, can interconnect to it's adjacent box through the conduit entry holes or they can be blanked off as necessary. This allows wiring devices of different voltage grades to be installed adjacent to each other and maintain segregation of the wiring as required by the national and international regulations.
  • the cable connection terminals Inside and on each side of the box are the cable connection terminals (8). There are twelve terminals for low current devices rated at 10 amps and below such as light switches and controls and eight terminals for power outlets (and higher rated light switches) rated up to 20 amps.
  • the terminal could be a barrel screw terminal as shown or any other type.
  • Each of the terminals are connected to a live rail (9) which is encapsulated in a slot ( 10) that takes the leg of the accessory.
  • the accessory when inserted in the slot (10) will connect it (Fig 6) to the cable system by the live rail (12) in the accessory being in pressure contact with the live rail (9) in the accessory box.
  • Fig. 7 shows the detail of the live rail connection between the accessory and the accessory box.
  • the fixing of the accessory to the accessory box is by sliding the legs (18) of the accessory into the live rail slots (10) of the box.
  • a fixing clip (11) will hold the accessory in place.
  • the accessory is removed by lifting the edge of the accessory with the flat blade of a screwdriver in the slot provided and disengaging it from the fixing clip.
  • the Accessory (Fig 6)
  • the arrangement shown in Fig 6 describes a typical socket outlet/receptacle for a British system. Variations on this would be used for the other types of outlet and also for direct cable connection to luminaires and appliances, etc.
  • the accessory comprises two main parts; the wiring device (13) and the cover plate (14).
  • the wiring device would be a standard design for each type of accessory.
  • the cover plate made of either plastic or metal, would be stylised to suit the architectural design and finish of the accessory and would be factory fixed to the wiring device.
  • the wiring device ( 13) is a plastic assembly incorporating a recess (15) for the spring clip (16) for the appliance plug (24) to connect to; and the live conductors (17) which become the live rail (12) which are connected to the accessory leg (18).
  • the back of the leg is angled (19) to provide additional support for the live rail when under pressure from the contact with the live rail in the accessory box.
  • the wiring device will interconnect the appropriate live rails in the legs to make the necessary interconnections.
  • the two live rails are arranged to have a slight interference fit when the accessory is inserted into the accessory box. Pressure is maintained, to ensure a positive contact between the two, by the inherent tension in the accessory leg due to the shape of the leg.
  • the leading edge of the live rails (9 & 12) are shaped (21) to allow easy entry of the accessory leg (18) into the live rail slot (10) in the accessory box.
  • the top section of the live rail is encapsulated in plastic (20) to prevent access to the accessory live rail (12) once the rail is in contact with the accessory box live rail (9).
  • the earthing/grounding rail will be longer than the live rails to ensure positive earth connection before any live connections are made.
  • the plug-in facility will provide connections allowing it to be used for but not limited to a) a single phase socket outlet (live, neutral and earth), switched or unswitched b) a two phase socket outlet (live l,live 2. neutral and earth), switched or unswitched c) a three phase socket outlet (Red, Yellow and Blue phases, neutral and earth), switched or unswitched d) a 20 amp double pole switch (live and neutral supply; live and neutral load; and earth) e) a fused connection unit (live and neutral supply; live and neutral load; and earth), switched or unswitched. f) isolators and isolating switches up to 20 amp rating
  • connections are always in the same location irrespective of the type of accessory to enable complete interchangability (provided the circuit connections are available in the box).
  • the plug-in facility will provide connections allowing it to be used for but not limited to a) 1 way lighting switches b) 2-way lighting switches c) Intermediate lighting switches d) Lighting controls including dimmers and infra-red controls, etc. e) Ceiling roses f) Connection boxes to luminaires g) Switch by-passes for maintenance purposes
  • connections are always in the same location irrespective of the type of accessory to enable complete interchangability (provided the circuit connections are available in the box).
  • the plug-in facility can be provided in different configurations, allowing it to be used for a wide number of other connections including but not limited to a) HVAC controls b) Audio outlets c) Telephone outlets d) Data outlets e) TV and Radio outlets f) Clocks; both mains and central g) Others
  • the accessory incorporates the switch, socket outlet, etc. connected internally to the plug-in legs which mate with the accessory box. Once plugged in the device is connected to the supply.
  • the temporary cover is a flat clip-on plastic cover that fits level with the top of the accessory box. This firstly protects the cabling inside and provides a surface level with the surrounding finishes to allow plastering and decoration to proceed without having the accessory fitted.
  • the temporary cover (22) is a flat plastic cover that fits into the recess at the top of the accessory box. This also has legs (23) to align with the live rail slots (10) in the accessory box. These do not carry a live rail.
  • a maintenance cover plate similar to the temporary cover plate, complete with live rails would be used as a lighting switch bypass.
  • the live rails would be interconnected to simulate a closed switch.
  • Fig 1 shows the general arrangement of the invention with the two principle parts, viz. the accessory box and the accessory.
  • the elevation indicates how the parts, including a plug- would fit together.
  • Fig 2 shows a section of the complete assembly
  • Fig 3 shows the detail of the accessory box based upon an accessory with a rating above 10 Amps, such as a socket outlet/receptacle.
  • Fig 4 shows a section through the accessory box to show the arrangements for the 4 no. 20 Amp terminals.
  • Fig 5 provides elevations of the accessory box indicating the arrangement of the flanges and the conduit entries.
  • Fig 6 describes the accessory in detail based upon a British style 13 Amp socket outlet/receptacle.
  • Fig 7 shows the detail of the live rail.
  • Fig 8 shows the temporary cover plate.
  • the maintenance cover plate is similar.
  • the accessory itself need not be installed until after the final decoration and perhaps not until immediately before hand-over of the building. This avoids damage to the accessory and reduces pilferage.
