Help, I have a situation where the City was to cheap get a new service. We replaced the Controller and spliced into a un-meter PGE Line as was the previous controller. At issue is we have wires for traffic signal inter mingling with street lights from two separate City meters, blocks away.

You would think common sense would say you can't do this incase a Traffic Signal Tech get hung up on a Street light from one of two places, or visa verse. Looking for code to back me on this.

Any help please
 
I appreciate your concern. This forum is about the NEC, and the NEC only applies on the customer side of the service point or meter.
I can’t tell from your description who owns the wires that are intermingled.
Are they overhead or underground?
Are there service disconnects?
 
All underground, we have traffic signals, that is using the street light pole for signals for a remodel. These are lights are on the North and South of the Median and fed from two separate locations, but not connected. We have connected to both these poles from a traffic controller that is being feed from a unmetered, unprotected PGE feed.

So we have a potential of three two sources at each pole, or in the case of an accident a chance to have several locations to turn off. It does not seem safe. There must be a NEC code against it, I am an contract tryin got protect the public on this one.
 
The wires a am working with are all downstream from the Cities Two Street lighting services, and traffic signal wires down stream from the cities controller cabinet.
 
We need to be careful about terminology.
When you say street lighting service, is that a circuit breaker box?
IE can the power be turned off to the wires in the conduit with the wires from the signal cabinet?
The wires from the signal cabinet, do they go to the signal heads?
Are there fuses on each phase to the heads?

The street lights are controlled by (2) different service locations with circuit breakers that are about 3/4 of a mile away from pole. The controller cabinet is a MLO with circuit breakers for the different phases of the traffic signals. This cabinet is located at the intersection. So at each of the poles there is a pull box, where we have the Street light wires from 3/4 of mile away and the Traffic Signal (right there) go into the conduit into the pole and up the pole.
 
One more question.
Are your traffic signals and wiring installed per the NEC, with permits and inspections?
 
So what I can determine is you have OCPD protected circuits from the signal controller and PGE wires that are hot all the time in the same raceway.
My experience is limited to one POCO, but PGE may be similar in not allowing unfused wires in the same raceway as fused wires (on the load side of a meter) as a short could by pass OCPDs.. The NEC rule is section 230.7
Your are dealing with NEC rules under the City of Berkley, and the POCO rules. POCOs mostly write there own rules under the scope of the NESC.
PGE likely has a customer service handbook that may say what they have done is not allowed.
And I am guess this is in a developed area, lots of concrete and pavement, and was done to avoid digging up and running new conduits.
I may not have the situation correct as it was a lot of back and forth. Start with Section 230.7, and who approved it. Also get the rules from PGE,. Put your concerns in writing and submit to supervisors.
A drawing with code references would help in making your case
 
I guess the added 230.2 E) Identification of Multiple Services. Where a building or structure is supplied by more than one service, or a combination of branch circuits, feeders, and services, a permanent plaque or directory must be installed at each service, feeder, or branch circuit disconnect location denoting all other services, feeders, and branch circuits supplying that building or structure and the area served by each

That would cover the street lights. But The controller has no disconnect so they are violating 230.70 Thank you let me know what you think
 
Thank you I think we both answered that at the same time. They screwed up and are trying to pin it on anyone else. They forgot that they are required to add metered service when they upgrade an existing intersection> PGE Construction takes a year before COVID and now even longer. but thank you again
