17 The ENEC symbol (European Norm Electrical Certification) is a European test and certification symbol for luminaires and electrical components in luminaires.
Luminaires with the F mark can be fixed to normal flame-inhibiting materials (EN60598/VDE0711).

The performance specification of the electrical circuits and fusing guide represents typical values obtained in accordance with accepted test methods and are subject to normal manufacturing variations of lamps, control gear and luminaires. They are issued as a technical service guide, but are subject to change without prior notice.
Circuit Protection for Multiple Luminaire Circuits (Non LED’s)
Within the electrical characteristics table shown on page 19.2, standard individual fuse values are quoted against each lamp type. These can be used when looking to fuse individual luminaires, however we cannot recommend fuse sizes for multiple luminairesdue to the individual nature of each installation.
We have no control over many variables. Therefore we would recommend that all installations are planned and installed with reference to the IEE wiring regulations (17th edition) which take effect from 1st July 2008. Using section 533 which deals with fusing, and section 559 which deals with lighting and luminaires, and any other sections of the regulations which are relevant to the installation.
Our only recommendation can be to use a type ‘C’ or better MCB, which will prevent nuisance tripping due to inrush currents.
When calculating fuse ratings please keep in mind the following points;
- High inrush current at initial switch on (as much as 25 times that of normal running current - although only for a few milliseconds)
- Running up currents
- Hot re-strike conditions
- Lamp rectifying during stabilisation and with aged lamps
- Peaks in supply voltage. In order to compensate for these high currents it is recommended to rate the protection device larger than those stated for normal running conditions.
The LED luminaire protective device, MCB (supplied by others), has to be able to withstand the inrush current of the luminaire(s) without tripping. The inrush current of LED luminaires is determined by the driver(s) and is not proportional to the luminaire wattage or running current. LED luminaire inrush currents can be as high as 400 times the running current for a very short time, generally less than 500us. This inrush duration is significantly less than the 10ms lower limit for conventional MCB tripping. However, some MCBs have a second tripping functionality, for inrush durations less than 10ms, having an increasing tolerance to high inrush currents related to the logarithmic inverse of the duration. Therefore Holophane recommends the proposed MCB manufacturers should be consulted regarding the tolerance of their products to the expected inrush current parameters. Holophane publish a table of inrush current parameters for each luminaire so that a suitable MCB can be identified by the lighting circuit designer or specifier.
Circuit protection is the responsibility of the electrical installation designer, as such, Holophane cannot advise on the sizing of circuit protection devices to be used, other than to make available the relevant luminaire inrush data, available via our web site or upon request if not listed
The inrush parameters, using the above link, are obtained from the driver manufacturers. As LED driver technology is in its infancy, the specification of drivers is likely to change more frequently than the lighting industry has become accustomed with similar products. We would therefore recommend that the inrush parameters are confirmed using the link, at circuit design, and again immediately prior to luminaire ordering.

In today’s ultra-competitive environment, it is becoming increasingly important to reduce operating costs to improve profitability. Holophane is your expert when it comes to delivering the most efficient lighting solutions to help you achieve that goal. Taking advantage of the most advanced technologies available, you can achieve an energy saving of up to 60%* over existing installations based on a point for point replacement.
