According to the invention disposed in the distribution boxes with switches control devices are used in order to switch the luminaire in accordance with the standby state of power supply of the general lighting.
General requirements and particular requirements for clamping units for conductors from 0,2 mm2 up to 35 mm2 included. From these terminals from the lamp circuit of the lamp is powered.
Portable power and signal distribution system for a controllable system dih multiple devices. The installation cost of the final circuits is only slightly increased by the fact that now 5-pole cables must be used instead of the previously required 3-pole lines. Welding Neck PN Is switched parallel to the first circuit.
The respective output circuits are in turn divided into a first and a second circuit. B pathway lighting to illuminate escape routes. As a function preserving usually 3-pole circuit to the vicinity of the first light to be supplied final circuits as a supply line in an inventive distribution box fed and from there to an alternating transfer required at least two end circuits by separate fused supply lines to the emergency lights of the final circuits placed.
In einem Verteilerkasten wird aus der Zentrale der Ersatzstromversorgung eine Versorgungsleitung In a distribution box is removed from the center of the backup power supply is a supply line 1 1 angeschlossen, die in Dauerschaltung geschaltet ist.

When both lights in duration circuit as well as in stand-by circuit to be housed in a common circuit, this switch-on readiness lights can not be realized. The final circuits such emergency lights contain a limited number of luminaires for.
This requires the installation of 4 final circuits full length between the lamps and the headquarters of the standby power supply for each room section. Equipment protection by intrinsic safety “i”.

By this measure, it has become possible now to mix modes of lights in a final circuit, twil saving a final circuit over conventional wiring. It is necessary in accordance with VDEthe lights of such circuits on two separately fused circuits, alternately arranged to divide. This in turn requires a high installation cost, if the control tekl and the lighting of the final circuits are arranged at a greater distance. Is a function preserving against the effects of fire line.
Spring clamp connections – General requirements, test methods and practical guidance. Loose Flange PN However, this requires both interventions at the headquarters of the power supply as well as in the individual lights, turn a lot of effort. Mounting platform for electricity meter unit, has rapid coupling for connecting unit electrically and mechanically without tools; unit is moved parallel to platform to locking position.
Roofed swimming pools and open air swimming baths. In the lamp itself, the lamp current circuit is connected to either the constantly applied with voltage circuit or to the controlled by the switch-circuit according to the invention depending on the method of connection of the luminaire. For this purpose, in each output circuit of the junction box fuses are arranged, which cause not a short circuit in one end circuit further supplied from the distribution end circuits to be disturbed.

In undisturbed panel power supply is located on the supply line to the mains voltage, an optionally present protective conductor is not shown.
This predetermined internal wiring can be replaced by a selector switch which selects between the two circuits, depending on the type of luminaire.
