Explanation of Voltage Drop at Ranch Properties & Shed Wiring Project

[@EdisonElectrical]

Oh look who rose from the dead. Great to see you’re well man.

[@avsrule247]

Really enjoy your videos, glad you're back! I love seeing the subtle differences between your electrical code in Colorado vs mine in Canada

[@anthonys7534]

Also remember that voltage drops don’t show themselves until you put a load on the circuit. Bigger the load, the more drop you get. A non loaded circuit will show full voltage

[@sparkyofsocal]

You can predict every aspect and every voltage on paper. Right down to 3 or 5% and 1% nowadays.

[@darbyl3872]

Is there a tester to find actual VD under normal load? Can you use a normal meter?

[@anthonys7534]

@@darbyl3872 Yes it’s Very Simple, just measure the voltage at the load while the load is running.

[@darbyl3872]

@@anthonys7534 Cool, thanks. I guess, by that time, the wire is either big enough or not (a little late, but if it needs to be redone, it is what it is.)

[@anthonys7534]

@@darbyl3872 exactly, but it let’s you know where things are at. Try to shoot for no more then 5% drop.

Glad you are back Josh, we missed ya. Good vid.

[@WeatherNut27]

Josh can be huge on KZbin like Steven Lavimonier with 163k subs. Keep these videos up. Not many worthy electricians filming and uploading their jobs. Great camera work too! Thank You!

Many years ago I did a ohms law ( yeah only for DC ) calculation on believe it was for ten 75 watt LPS luminares that were 100' apart on a long 1,100 driveway. Guys sparky dad said to only run #12 from panel. Had him run #8 to first luminare then #10 for maybe next 5 luminares then #12. With all the luminares on he had 108 volts at last luminare. Was within one volt of what I calculated. On large transformers they usually have 5 taps 2 @ + /-, 2@ 2.5% +/- and center tap at rated voltage. Had to up taps to adjust for excessive voltage drop at older like you stated much added on remote building.

[@KevinCoop1]

Is there a ground rod at the first shed panel and the new shed as required by NEC? I would suggest you do a voltage check from ground to neutral. If there is a voltage measured between N&G, then the ground rods are not there or the connection is not good. Once you get the voltages settled with grounding fix you need to turn on the lights and what an assumed number of people can be using at the same time to see if there is a voltage issue. Respectfully, Kevin

Glad you are back.

[@alfredoleandro8260]

Good work 👍 Enjoy Your work ethic

[@rupe53]

personally, I'd be working my way back to the house to see where the voltage difference starts. Might be as easy as balancing the 120 volt load at the home panel.... and double checking the neutrals there too.

[@jasonault3511]

You should have ran your 12/2 in shed vertical. People could hang stuff on wire in my opinion. Also sharpie markers? Why don’t you use stickers for labeling. Outside understand but inside panel I would use sticker.

[@oddjobz9858]

Would have ran MC just incase they don’t live up to covering everything.

[@joshk2181]

It's even worse on a modular synth when you're depending on the voltage for an exact pitch

[@sparkyofsocal]

What’s the voltage at the service? Curious as where the voltage disparity starts. Point being the issue could be the utility company.

[@rupe53]

I thought the same. It would take some leg work but finding where it drops can be a game changer, especially if it's easy to balance the 120 volt load.

[@antarsantiago]

Hey man! Happy to see you!

[@williamwallace732]

The champ is back

[@tallbrian100]

Sub panel to a sub panel to sub panel. What could go wrong.

[@joehead1294]

Maybe fire suppression?🤣

[@Bryankrall8090]

The man the myth the legend is back.

[@jasonault3511]

Also I would suggest solar for barn and shed

[@stephenb5757]

So glad you are back!! Great job

[@lloydmills9619]

Huh, I've been studying the NEC for decades and thought a panel feeding a seperate structure had to be service rated and had to have its own GES. Of course I never heard of not being allowed to use an approved wiring method horizontally. So ...

[@stillthakoolest]

It does. Use a MLO panel too or bolted main breaker

[@R900DZ]

What are the possible causes for the imbalanced voltage for the two sides of the phase coming to the shed?

[@WeatherNut27]

When I had my imbalance a loose neutral and an old crusty service drop feeders was the issue. Also noticed dimming and disco lights when washer was on. Tell tale sign of loose neutral. Once I upgraded, everything got fixed including the voltage difference

[@matthewrichards5941]

This looks like a loose neutral to me. There are a lot of terminations between that shed panel and the transformer.

[@JasonEDragon]

I had an imbalance like this that I primarily noticed when my sump pump kicked on. I then measured the voltage and saw one leg would go high and the other low. I called the electric company and they sent someone out and pulled my meter. Turned out a branch had broken the neutral in the service drop cable and one of the hots was damaged and partially energizing the neutral. I have a few UPS backups for desktop computers and now I keep the display on to show the voltage all the time.

[@johnhershey4010]

Great Video Peterson. could they run 480v to the Big shed and then with a step-down transformer 120/240 would that work?

[@illestofdemall13]

That isn't necessary, all they need to do is size conductors accordingly. 480 is only practical when you need it for special industrial machinery.

[@sparkyofsocal]

Utility companies don’t typically supply two different systems anymore. You get one service and you make it work. As a reminder the voltage drop actually starts at the utility transformer. So just bumping up wire size without the math is not the best option sometimes. I agree that the conductors from assuming the service at the house may be to small already. The conduit is already in and paid for. To get larger conductors in would be a tough sale to owners without them being open to facts and understanding math.
