Still cannot make the distinction from here, without assumption. Is it a legally-required emergency system? If it is, you are likely in violation of 700.10(B).The site is a data center the em power is from a emergency switchboard backed up by a ATS (generator).the job is part of a transportation system.
Thank you
If the standby power were for the actual computers and the transportation system would be shut down in a hazardous (to life) way if the computers failed, then it might well be emergency power, or critical operations power, or whatever.
Hi I am on a job were the site lighting has emergency power and normal power in the same raceway . Is there any code issues I should be aware of ? The voltage is the same.
You need to ask the design professional,
Nothing says that the normal egress lighting for an exit has to be mounted to the building.
If for instance the parking lot light is providing normal lighting by an exit instead of a wall pack.
I do no of any requirement that dictates that a pole fixture cannot provide the correct level of lighting to be considered egress lighting. This came up on a rear exit at final a while back.
The loss of the panel for the wall packs no emergency lighting, yet when the pole lights where lost the emergency gen kicked on. The pole lights provided enough normal lighting source to be considered egress lighting.
I am going to disagree here, if the lights are not required egress lighting they can not be added to an emergency supply. They would be optional.
In what scenario are parking lot fixtures required egress lighting?
If they where required they had better be equipped with re-strike lamps as well.
