I have a 1” PVC conduit feed from the panel to a pole light. This is existing. I want to pull another separate circuit thru the 1”.
The separate circuit will run thru the pole and feed an EV charger. Two Questions: Can I use the pole as a junction box and can I run a conduit from the pole to the EV charger. No splices. I would have to pipe near the hand hole cover and down the caisson. Not sure if this makes sense.
 
I don't know of anything prohibiting this in the NEC however the installation instruction may have something on it, IDK. There are others here who have worked on these lights -- I have not done many at all.
 
What voltage is your charger this could apply
210.6 Branch-Circuit Voltage Limitations. The nominal
voltage of branch circuits shall not exceed the values permitted
by 210.6(A) through (E).


(D) 600 Volts Between Conductors. Circuits exceeding
277 volts, nominal, to ground and not exceeding 600 volts,
nominal, between conductors shall be permitted to supply
the following:

(1) The auxiliary equipment of electric-discharge lamps
mounted in permanently installed luminaires where
the luminaires are mounted in accordance with one
of the following:

a. Not less than a height of 6.7 m (22 ft) on poles or
similar structures for the illumination of outdoor areas
such as highways, roads, bridges, athletic fields,
or parking lots

b. Not less than a height of 5.5 m (18 ft) on other
structures such as tunnels

(2) Cord-and-plug-connected or permanently connected
utilization equipment other than luminaires

(3) Luminaires powered from direct-current systems where
the luminaire contains a listed, dc-rated ballast that provides
isolation between the dc power source and the
lamp circuit and protection from electric shock when
changing lamps.

Informational Note: See 410.138 for auxiliary equipment
limitations.

Also you would have to ask your AHJ if drilling a hole in the pole will void it’s UL listing
 
It would be a challenging pull in and out of the pole.
On drilling pole, I have seen it done a lot, but this is on large signal poles
Can you expose conduit next to pole, cut in 2 90s, add send 90 over to charger, and then set handhole over 90s? This means of course cutting pavement, etc, but pull would be much easier.
 
Thanks Tom. The 1” conduit run is over 75ft. Underground. It feeds a pole that’s only 8’ away from the location where I’m setting the EV charging station. The 1” conduit only has (3)#10’s. I was able to pull the wire back and forth so I know the pipe is not compromised. I need to pull in (4) more # 10’s (2) 208 single phase circuits to supply the EV stations. I’ll just need to come out of the pole and trench 8ft. I’m just not sure what the inspector will think of it. I’m trying to avoid having to trench through rock and clay that is the Colorado soil.

If the pole flange is raised high enough off the base, you can run conduit between the base and the flange, and notch the bolt cover. That way you do not have to drill the pole. If it is subject to damage, and you need rigid, I use a bond bushing on the end inside the pole.
 
I'll take a look and see if I can squeeze a 3/4 under the flange. I don't want to drill the pole if I don't have to. And yes it could be subject to damage. I'll use rigid for sure.

This is the my first forum so thanks for all your help.

That's six or seven CCCs. What are the lighting and charger loads? Just curious.

Should you use #8 for the charger circuits? The conduit size is not an issue.

Any chance you can build a concrete curb above ground to encase the conduit?

If not, remember that RGS only requires 6" of cover if it won't get driven over.

If they didn’t pour the concrete over the leveling nuts, you should have enough room. Sometimes they grout around under the flange, then you have to hammer drill a hole.
 
Hi Larry,

The lighting load is small. Retro fitted to LED. 30W LED X 3 =.75A EV charging stations load is 24A. Using 30A 2P breakers. I'm adding an additional circuit for future charging station.

I’m with Larry go with 8s a #10 ground will work for #8 hot
