INSTALLING POWER FOR TRAFFIC LIGHTS!!!

Haha 13:00😂, that cold weather must be stiffening your hands. Great video!

As long as you can find things in the back of your truck, it isn't messy. 😁

Just wait until next week, Steve. Bundle up, Brother.

25 kVA is a pretty small transformer. Metal weatherhead on PVC? Interesting. 18:39 The signs in the weeds there are funny to me.

[@jsncrso]

It's running a traffic light and some street lights. My house and three others (all 200A electric) are fed from a single 25kVA transformer and there has never been an issue, even when I ran a 27kW electric tankless water heater). They are made to output 3x of their rating for 3 hours minimum

[@jovetj]

@@jsncrso I never stated it was too small to run a traffic signal and some street lights. I'm pretty sure 75kVA is the smallest residential transformer used in my area. Different utilities have different levels of optimism.

@@jovetj in the past year this area has grown a lot and more neighborhoods are being added so I expect upgrades in the near future!

[@thebozkin5087]

In my area if you do an underground service it has to be 200 amp service installed no smaller even for a traffic controller

[@jsncrso]

This most be a small Co-op power company. Bigger power companies, at least in the Eastern US, requires everything up to the meter or service disconnect to be installed by them

[@Trafficlightdoctor]

How would you ever get anything done in a timely manner!! 🤣 it’s a fight to get them out here to complete 15 minutes worth of work half the time!

[@mikel9567]

That's not exactly true. It depends on the installation requirements. Aerial wire, poles and transformers are installed by the power companies. Underground lines are typically ran by electricians. Power company hooks up to the main line and also installs the meter since that is their property.

Comment on the messy truck ? We're pretty used to it! haha

It’s a fight to have the guys keep up with them! In a perfect world I agree but 90% it’s a waste of money.

A very good Thursday afternoon to you in the USA from Wellington Somerset in the UK

[@jadenalexander1153]

So do you think our fire trucks look weird compared to urs?

[@kyleftw1679]

Also do you know what that antenna looking thing is next to the power pole you were working on is for? I've been seeing them lately and dont know what they are. Thanks!

[@Trafficlightdoctor]

That one is a cellular repeater tower! They look pretty similar to a modern tornado siren though so it could vary depending on your location!

[@kyleftw1679]

@@Trafficlightdoctor True! , thanks.

[@JustAnOldMan56]

As mentioned by jovetj, 7200 is an often used single-phase distribution voltage. The secondary of the transformer produces 240 volts (Primary voltage ÷ Turns ratio = Secondary voltage. 7200 ÷ 30 = 240) and the center-tapped neutral provides the 120 volts. A to Neutral = 120 volts, B to Neutral = 120 volts and A to B = 240 volts. Single-phase power split into 2 legs; A and B. Good luck with Entergy. They are a dictionary-example of obdurate. Truck: What counts is how it looks when you roll up to the first job of the day.

[@Trafficlightdoctor]

@@JustAnOldMan56 this is what I love about sharing this stuff with you guys! Let me not say my opinion on entergy until they finish the work! Lol

I wonder how cold? 50f? We just hit 0 this morning, might make it to 10f today.

@ yeah that’s a bit chilly, we have been below zero, and teens the last couple of days.

[@diegojines-us9pc]

people should know. a simple 4 way traffic light costs about 10K a year to install, operate, and maintain. someone getting rich.

[@Computist40]

12:20 Hey missy cool your jets. LOL, I'm just joking, I can imagine that's quite annoying, especially when it's cold outside.

[@BartlettTFD]

From all of the wind noise, that would have to be a miserable day in the bucket😩

[@jeffreykornspan9053]

I'm surprised that you are using such a small size and a manufactured cable for Service Entrance instead of using single conductors in your conduit and a larger size even though low amperage service for your traffic controller system.

[@jovetj]

Why spend money on heavier cable that just isn't needed?

[@jeffreykornspan9053]

@ Aren't these inspected by authorities? I do know sometimes you guys are considered a utility contractor with no inspections Funny!

[@jovetj]

@ "You guys"? I'm not Steven and I didn't make this video. I don't know how inspections work in this jurisdiction. I presume as long as they follow the utility's standards and practices that the utility will be fine with the service drop installation. I was surprised the existing service on the pole had conduit standoffs and the new one he installed didn't use them. I'm pretty sure Aaron from Bobsdeclline would have some things to say about Steven being so close to the transformer's lugs and high voltage feeder, though.

[@jeffreykornspan9053]

@@jovetj Yea, no 1000volt gloves ! I'm surprised with no inspections.

[@mxslick50]

@@jovetj Why? Because they are directly connecting to a transformer without any fuse or breaker protection sized to that tiny cable. Did you notice the title text "Joke's on me?" I'm betting the power company made them pull out that skinny cable and install at least a #6 set of wires, as that is the absolute minimum size most power companies allow for ANY feeder tapped directly to a transformer, no matter what the load is. The OLY time they allow smaller wire will be directly to a single streetlight on the same pole, as was done on the one in the video. The idea behind #6 minimum is even at the full current of that transformer, a short will not instantly turn the wire into a glowing heater element. That wire he pulled, if it ever shorts, WILL turn into a red hot heater element just like in a toaster. (It's resistance would be just high enough to do that, rather than blow the transformer primary fuse.)

[@thebozkin5087]

That is shorts and T-Shirt weather

[@michael_horsley]

Trying to figure out how 110+110=220V. Seems like it should double the amps, not the volts, but it does.

[@jovetj]

U.S. single-phase service is 120/240, not 110/220. (Yes, it matters) It does double the amps. If you halve the voltage, you double the amperage for the same amount of power. This is why transmission lights are such high voltages-more power can be sent down the wires without having as thick of wires. Single-phase transformers typically transform 7200 distribution voltage to 120/240 voltage for homes. The secondary winding of the transformer has 30× fewer windings than the primary winding, so the voltage is reduced by 30. That secondary winding provides 240 volts. If you only use half of that secondary winding, then the voltage is reduced by 60 and you get 120 volts. This is made simple with the neutral secondary connection tapped into the middle of the winding so that you can utilize each half of the winding for 120 volt circuits, or the whole winding for 240 volts.

[@michael_horsley]

@jovetj It's not the math, 110, 120, whatever. If 2 outlets in a home were used to power something, voltage would remain the same. Could draw twice the amps if they're on separate breakers. Volts stay the same. Series vs parallel in battery terms

[@uzlonewolf]

It's because it's a center-tapped transformer with the neutral halfway between the 2 hots. Think series, not parallel.
