Street Lighting

[the blur]

Residential street lighting. HID's on top of 8 foot poles. I watched a crew install some. There is no ground, they just grab a secondary, and a netural, and drop them down a pole, using direct bury wire, no ground, no service entrance, no fuse, no protection. no metering, no nothing.

How do they get away with it ?
What if something shorts out?

Sounds like it must be the POCO setting them up.

Shorts to what, the wood pole?

That is what I was thinking too.

we use something like this to fuse the wire in the XF or at the pole where the run originates.

Also we bond any metal parts to the neutral, usually it is just the light head itself unless we use aluminum poles

The town is responsible for the street lighting, and they sub it out to an ec.

That explains it better than I ever could. Except in my neighborhood, there is no meter, no service entrance, no ground. They just grab a secondary and a neutral off the POT, and away they go.

If fact, they use the virbrating machine to drag the wires through the ground. I know some lawn sprinkler guy will eventually hit one of those UG feeds, as they are not deep enough.

They need to be at least 18" to meet with NESC.

Being 8' poles, I would venture a guess they are metal decorative, unless there fiberglass.

Its the difference between the NESC and the NEC. NESC is a performance document, you engineer to create what we do per the prescriptive rules in the NEC. IE the NEC tells us exactly how.

The NESC leads to this
