I was just reading the Mike Holt?s newsletter from yesterday and item 14. (?The flexible connection to emergency system equipment in hospitals?) is something I?ve seen allowed in my area. Part of the commentary reads:

?The intent is clear that it is only permitted "where necessary" not where convenient, possible, preferred or easier! The option to use a flexible wiring method would have to be "identified" as "necessary" where it relates to the connection of the equipment and "approved" by both State and Local Authorities Having Jurisdiction. If the intention to use a flexible wiring method in this application to connect emergency luminaires is for reasons of convenience, preference, ease of installation, or financial, it is not considered "NECESSARY!"? (see www.nh.gov/electrician/14_2005.html for the complete commentary and code references)

I have never had an inspector point this out and not allow flex to emergency fixtures. I?m curious if other AHJ interpret it the same way?
 
Re: Mike Holt's "Most Common Installation Deficiencies

Neither the local or state A'sHJ have a problem with flexible connections to EM system luminaires in my area.

IMO it pretty near to rediculous to require hard pipe connections for these luminaires.

If an event has occurred that would damage a ceiling or wall to the extent that a metallic cable has been damaged behind or above it, it would be necessary to evacuate the area served by the circuit(s)anyways during the repairs.

What could damage a concealed cable to a luminaire in a hospital that would not damage the structure or finishes?

If I am following this correctly I would prefer and believe code would agree using Flex or MC to exit/emerg.,etc. would be acceptable. Ex. "Grid caddy" removal of panel or grid versus EMT, etc. les chance of damage ?

I was in a hurry when I posted that hope it made sense?
