How to Control Lights?

You might do a Google search on "light switch" or "lighting contactor".

look at powerline carrier control.

I used to do a lot of work with a company that was great with commercial equipment, but they've switched.

good luck

I suggest you look at so-called "smart relays" (e.g. (click here>), with the outputs connected to contactors to actually switch the lighting circuits.

Something like this maybe...

"What I have to add to the Feeder Pillar to control the lights and switch the specific lights off?"

Add a timer.

a timer at each light.

It would be interesting to see them flicker on/off at a closely synchronized time.. And inexpensive

I think most lighting is 277V.

120v or 277v or a 1,000v, seems we have another troll or someone not wanting to do their own HOMEWORK! Oops, I can't say that anymore

Again, we have an OP with a handle insinuating they know what they're talking about.

The OP needs to take Redfred's "free" advice and hire a qualified electrician.

I don't know, maybe I'm suffering from PHSD (Pre-Holiday Stress Disorder) (Post Holiday Stress Disorder), my wallet has been shot-out and my credit cards max'ed out!

Now, only if I get to next weekend

Where's the Trump relief fund?

Relief fund?

Maybe you could try selling some au naturale pix of his latest wife?

Never mind, everybody's already got 'em.

I'm an engineer since 2007, but I was working in a field totally different than what I'm doing right now. and I don't have any one to help me in this company regarding the street lighting.

Please grow up in answering people!

To switch off street lighting when it gets light in the morning & on at night when it gets dark most places use a daylight switch usually 1 on each light. A Timer would possibly have to have the time reset after a power failure unless they have a battery backup built in.

In the case of having some lights to turn on when others are turning off or off when others are on, You could use a relay with a double throw contact controlled by the daylight switch.

If you have a group of lights all on the same circuit to be turned on & off at the same time, a contactor controlled by the daylight switch could save the expense of a daylight switch on each light.

Using a contactor with normally open & normally closed contacts you would be able to have 2 sepperate circuits.

use the normally open to turn the circuit on for the lights you want on

& the lights you want off at that time use the normally closed contact to supply the second circuit

sorry I misunderstood the original post after rereading it I realized I was off track

Thank you for answering the question in detail. you are the only one who understood what is the question exactly meant :)

the point that i suggested to the client to add at each light, but they refused they need a solution from the Lighting Panel itself. as the network is an existing once and they don't one to touch the poles. they want to have a solution from the Lighting Panel itself. the timer as most of the people answered may help to dim on the lights, but it will dim it all or turn it off all at the same time, what i want is what you answered is to have on-off at the same time, but without touching the pole.

A standard timer is an on/off control, not a dimming control. Use a timer to control one or more lighting contactors (depending on the circuit layout and loading as a standard timer's switching contact rating may not be high enough). Locate all of this back at the lighting control panel since you cannot touch the poles.

This is how we control our distributed building air conditioning system but the principle is the same for a centralised controlled lighting system like yours.

You will need to hire an electrician to do the work for safety and legal requirements.

Note - This may not be possible depending on how your pole lighting is wired up, so don't forget to check (or get someone qualified to trace the circuits if building wiring drawings are not available). For example you will not be able to switch half a string of parallel-connected lights from a central location.

It is not possible to do so unless your street lighting have double set of the ABC cable running along all the street lamp pole and each street lamp take separate power supply from each set of the ABC cable. With that, you can have alternative street light up according to the timer you set.
