what wiring method do you guys use from the exit light to the egress light.
I have been using thermostat or bell wire, should i be using conduit, or thhn?
its only 6volts


A 50w lamp at 6v is 8.3 amps, would you run your refridgerator using bell wire

Just curious -- Indoor exit sign, outdoor light? Or is this an indoor remote head powered from the exit sign? If it's indoor exit, outdoor light it would violate 700.12(F).

Thank you for pointing that out. :cool:

For battery unit load side conductors I have never used less then 12 AWG and often we use 10 AWG, voltage drop is a killer when your only dealing with 6 VDC to start with.

What size fuse is in the output circuit?

Normal conductor overcurrent protection rules still apply to 6 VDC circuits.

BTW our method is to use the same method the line volt is done in. EMT, MC, NM, etc.

not getting many responses on what others use.

My answer, then, would be "I would not do this at all." IMO it's a Code violation to supply an outdoor emergency head from an indoor exit sign. I would require a separate battery pack for the exterior emergency light head, supplied from the outdoor lighting circuit. In general, unit equipment has to be fed from the normal lighting circuit for the area that the emergency light serves, so unit equipment for interior lighting has to go on an indoor circuit and unit equipment for outdoor lighting has to go on an outdoor circuit. I guess it's possible that the same normal mode circuit could be used for the normal lighting on both sides of an exterior door, but I don't recall ever seeing it done.
