| MAINS CONNECTION MODULE | 1.87 m long with 6 x 32 Amp sockets at 300 mm centres. Connects the system to a mains supply via the built-in terminal chamber. |
| EXTENSION MODULE | 1.87 m long with 6 x 32 Amp sockets at 300 mm centres. "Pig-tail", of desired length, exists at one end and terminates in a 32 Amp unfused plug. |
| FLOOR BOX CONNECTOR | Floor box connectors (tap offs) are available to any specified length. Everything in the circuit is rated at 32 Amp and therefore not restricted to 3m. |

| SINGLE CONNECTION MODULE | 2.0 m module with 6 x 32 Amp sockets. Terminal chamber at one end. "Flying lead" of desired length exits other end. |

As above but plugs and sockets are Red with a non-standard "D"-shaped earth pin. The earth busbar is isolated from the metalwork to form the clean earth. A second earth wire is fitted to "pig-tails", "flying leads" and floor box connectors. Earthing screws are fitted adjacent to each socket. |
Note:
Modules have integral fixing flanges at each end which raise the module
3 mm off the subfloor. Additional spacers can be supplied.

floor layout demonstrates the flexibility and versatility of the Powerfloor
system.
Flexible conduits
take the modules simply and efficiently into the corners of the
floor as demonstrated. These leads are not restricted in length |

Typical Busbar Layout Design
Copy typical layout drawing on PG. 8 & 9 of heading "Complete flexibility in the distribution of services"
The layout demonstrates the power, voice and data systems in almost continuous, uninterrupted configuration. The rows are at 5m intervals; the radii, here 3m, show that the floor outlet boxes can be plugged in at any point; sockets for all services can always be easily accessed. The further versatility of the system is demonstrated by its ability to conform to both the physical requirements of the project and its budget.
Module could be at 7m intervals and employ 4m tap-offs, or 9m intervals and employ 5m tap-offs. Similarly, instead of being continuous and perhaps offering an unnecessary surplus of sockets, judicious use of "pig-tails" along the linear runs of modules would reduce the number of modules, hence the number of sockets and subsequently the cost. The options are infinite. Above, are just a few examples.
Designed to Individual
Specifications
Generally, Electropatent will design on a 3m grid, with one floor box
to 9 sq. m, giving about 40W/sq. m. For a dealing floor, 3 - 5 Amps per
desk would be allowed. In some instances, each dealing desk would be on
an individual circuit. Generally, a maximum of four dealing desks would
be on a circuit.
The composition of the voice and data design will depend on the content of the floor box, e.g. 2 x LJ 6C (secondary) sockets in the box, would require 2 x LJ 21/A (master) sockets under the floor. Similarly, for RJ45 sockets and so on.
Some clients prefer "island" modules. These afford the facility to lift up a floor tile and, within the line of vision, see a concentration of sockets. Electropatent therefore, do not restrict the options to 2m and 1.87m modules. They can be shorter and concentrated. However, a minimum of 150mm is needed between the power sockets if plugs with flexible conduits are to be employed. This then ensures a smooth radius on the conduit as it projects from the plug towards the floor box.
40 Amp Rating
By using 6 sq. mm cable for "pig-tails" or flying leads, the
system then becomes rated at 40 Amps. Short circuit tests have been carried
out by ERA at this rating with excellent results. At this rating tap-offs
remains at 2 Amps, still employing the 32 Amp unfused plug.
