What does this symbol mean?

[Madison]

The attached image has a symbol in it that appears on a sort of electrical schematic that is part of blueprints for a new building. I am awful at dealing with anything having to do with electricity and working with architectural prints is stretching my skills in the first place.

Can someone tell me what this thing means? It's all over the drawing and appears, conveniently, everywhere we'd like to have power outlets. I'm trying to do as little repeat work as possible, so if this happens to mean "put power outlets here!" then I'll be very happy.

Very interesting. I never seen this either. I'll check around at work for ya.

I'd have to see it in context. Are the numbers the same, or sequential, or grouped (like 10 of #27, 10 more of #28...). But, I admit, it's not a symbol I have ever seen before.

Online references don't show anything like it.

Good example of a bad drawing symbol...

Maddie,
I have occasionally seen symbols like this but it isn't a standard that I can tell. When I have seen it before it was indicating a three bulb/tube light fixture and the 27 indicates either the lighting circuit or the lighting panel to which it is wired. Again, it would help to see it in context with other parts of the circuit.

Thanks, everyone.

A coworker that's more experienced working with architects told me it's a light source and the subscript represents the circuit it's on, but it's on a drawing that has no other light sources and it's a non-standard symbol, so I'm skeptical that's the case.

Also, several of them appear in the middle of structures that stretch from floor to ceiling, so it'd be peculiar to put in a light where nobody will see it.

The search continues...

It may be a safety light. One that remains on when all other lighting is turned off. It also may be a power failure lighting device. Since it is an archetectural drawing there should be other schedules attached in the drawing bundle. Find the one (or several) that list electrical details and look for the symbol in that list. There should be a reference to the fixture type and there may even be a bill of materials.

This maybe to obvious but could you just ask the people that made the drawing? I've ask several people at work and even checked our own prints for our facility. Which is a chemical plant with several differant types of structures and various levels of safety exposure.
