Photocell controlled light

Recommended Posts

What is the proper symbol to show on a 2D residential plan for an exterior wall light that is controlled by a photocell?

 

Many thanks!

there is such a symbol in the Library Browser, you may need to add that particular symbol to your Electric Legend though.

I just annotate it.  I would not trust a contractor to know what a symbol ID meant, other than maybe GFCI, and DM.  When specific types or brands are involved, I prefer a fixture schedule.

My copy of the NECA national standard is old (2006) - it was updated in 2013, but the 2006 version addresses photocell controls only in section 5.0 Motorized and HVAC Equipment - Controls:

If the photocell is independent of the fixture (maybe it's controlling multiple fixtures), then the NECA standard symbol may be appropriate, but realistically it makes more sense to annotate the fixture symbol with 'PC', and define what 'PC' means within your own electrical symbol schedule:

Or, if you're publishing a fixture schedule (or specification), identify the fixture on the plan, then specify within the fixture description that it is to be controlled by a photosensor:
