Permanent Barrier

[bfingland]

I have a situation on a hotel project where normal and emergency lighting circuits are switched at the same location with different switches. I would like these switches to occupy the same back box so that a single cover plate can be used. Per NEC 700.9(B) this wiring must be separated, but per NEC 314.28(D) they are considered separated with a permanent barrier installed.

Can anyone point me towards a 2-gang or 3-gang product that has such a permanent barrier?

Or is this something that is typically field installed? If so, is it welded to make it permanent?

Thanks.

Emergency lights are usually not switched.
It sorta defeats the purpose

Your local supply house should carry dividers that fit in your boxes.

I am seeing a ton of emergency lights that are switched.
They are wired with relays that switch the power source from switched to constant hot in the event of a power failure.
A lot of schools are doing this to save on energy costs. There will be one or two left on 24/7 in the corridors and the remaining will be wired with relays either already factory installed in the lights or they are using RIBs.

Our AHJ approved the barriers for switching as you described, but this might not be the case elsewhere. The barriers were adjustable in depth, used with a special mudring, field installed.

Bodine GTD emergency lighting relay control devices were used for the switched emergency lights.

i actually have a similar project where lights are on a dimmed circuit and also elrs [em lighting relays] from inverter source.THis is a high end lobby where the em circuit picks out every fifth light.Should these conduits feeding the lights be seperated?which btw is unacceptable.[all work is exposed]

I wouldn't take a chance, I'd use one of these:

I'm not fully picturing your installation, but there is no exception for "unsightliness" in 700.
