Emergency Lighting Cable?

Emergency Lighting Cable?
I've just read on another post that emergency lights should be wired in fire proof cable.

I can see the point when there is a central battery backup involved.

But whats the point in wiring a self contained fitting in FP? Surley its benificial to have the fitting supply cable burn through?

Have I missed something here? Rules

I was under the impression that self-contained could be in normal cable but the central battery systems had to be in FP.

I am certain that self contained units can be wired in non FP cable, unless the regs have changed recently , but cant see any benefit in FP cable

the only reason would be to surface mount the cable?

however you can get white non fp "earth protection" or whatever nowadays ?

RE: Emergency Lighting Cable?
unless it CBU then you cant use FP, it has to be the same as the cable that is used in wiring the lighting circuit.

Then, if you have 3 hour duration to maintain, how TF do you comply, standard fp is out the window, and enhanced is only an hour or so if memory serves us correctly.

RE: Emergency Lighting Cable?
Can't find my 5266 but I know it specifically states that self contained EL should be wired in similar cable to the normal wiring.

Simply because if there is a fire and the normal lighting cable burns through you don't want a fire proof cable maintaining the electrical feed to the EL fitting thereby preventing it from turning on.

Hi might have been me that started this discussion, I have been assured that it is all new cabling to any emergency light. I will go back to my font of all knowledge tomorrow to get chapter & verse (unless Lance reads this and confirms my statements)
