Mixing LED and HID
Mixing LED and HID
(OP)
Can I run the LED EXIT signs (Crouse-Hinds CCH UX..)in the same 120 VAC emergency circuit of HID fixtures (C-H VMVS..)? The circuit is fed by the emergency panel.
NEC 240.83(D) states "CB used as switches in HID circuits shall be listed and shall be marked as HID". Does this mean LED is not permitted in the sole HID circuit?
Thanks.

But pay heed to HTNeighbors comment. If your HID fixtures are to remain on 24/7/365 along with the exit signs, remember to lock the breaker down. If you intend to switch those HID fixtures on and off, the exit signs need a separate circuit.
Best to you,
