It would be best to speak to the lighting manufacturer for details although I guess seperation by 50mm will be sufficient. (although 100mm may be prudent) I guess as the cabling all goes to the same point anyway there is little little interference from the emergency power and data but there will be other power cables to consider.

As far as I know that if the emergency lighting cabling is not contained within the fitting then it must be segregated by a earthed screen capable of withstanding a fault current from other circuits.


Why do we need Vernier Calipers when we have container ships?
