circuit information on drawings

[ph196]

For those familiar with electrical design of buildings and creating CDs....is it required to show the panel name and circuit number if you are reusing an existing breaker for a different application, i.e. a renovation project? Or is it more a matter of what the owner requests?

If I understand your question correctly, I will ask you a rhetorical question...

Is it necessary to update your panel schedule when you use an existing breaker for a different application?

If you don't tell the electrician where they have to go to shut off the circuit, you increase the chance that he'll try to work on it hot - never a good work method.

Yes, it is required, so the work can be done safely. If you can't tell where the circuit is fed from, at lease put a note on the drawings telling the electrician to trace it out and shut it off, and update the panel schedule.

I was in a building that had breakers, in three different panels, labeled air compressor, old air compressor, and old air compressor. All of the breaker were wired and on. The current air compressor was located next to and fed from the service switchboard.

I am showing the location in an existing panel schedule, but I am not showing a new homerun going off of an existing device, Its showing a wire with a continuation symbol and a keynote, the keynote elaborates what the circuit is intended to be used for and the breaker requirements, which are reflected in the schedule. I thought typically you only show a homerun with panel name and number off of a new device...these are all being reused.

The existing electrical drawings do not align with the panel schedule photos I have, so I'm taking an educated guess as to where they should be connected to the panels, the contractor will still have to verify much of this.

Thats kinda a backwards then forward then backwards kind of explanation...
If you are simply extending a circuit then it isnt a homerun. But the existing should still be spec'd and marked for allowable use... Otherwise, just note "find any ol' circuit" then off to the races...
