The most gangster trick is the wire manufacturer shorting you 50 feet on that new spool.

Most gangster shit ever when I pull this trick out on the field and leave the rest with their jaws on the floor amazed how smart I will look.

Actually the most gangster electrical trick is running an extension cord from your neighbors house...

1st- Get resistance rating 2nd- Divide 2 ohms by measured resistance. 3rd- Divide 1000’ by second step answer. 1st-.4 ohms 2nd- 2/.4=5 3rd- 1000’/5= 200’ You’re welcome

This is why i love hanging with the elders..... they got experience, knowledge, and the wisdom to know when to apply that knowledge...

You’re the only dude that actually read the manual. Great advice

Here's another trick: If you have a wire with a broken conductor but you can't find it visually, check the capacitance across each end. The ratio between the two values will give you a *very* rough position to check. It is most likely to be useful if the break was caused by metal fatigue at one end or the other, as just _bending_ the wire will change its capacitance. It has saved me a lot of time because I knew which end of a power cable/etc. to cut back and redo. Cheers!

Every electrical engineer is rolling his eyes

I’m glad there’s people like you because even after you explained it I have no idea what to do when it comes to electricity. Thank you for what you do

My boss is always like walk this out and find out how long it is. Not anymore buddy haha

If you really want accuracy and just want to use basic tools, get a power supply capable of supplying a constant current of one amp. Connect it to the wire with an ammeter if your power supply doesn't have an accurate readout. Put your DMM in low range DC volts and measure the voltage at the wire itself. The voltage is the resistance, and you can reliably measure down to single millioms with the percent accuracy of your DMM. Even the cheapest DMM should be within one percent.

By that logic the accuracy of 2 decimal places can be as much as 90 feet give or take. Weighing the roll gets you within 5 feet per 1000 foot roll. Weigh an MT spool, weigh 1 foot, weigh partial roll. Subtract MT spool, divide by weight of 1' of wire. Done, within 1 foot give or take.

im the kind of guy who just bring much more cable then i need

_"According to my meter and all this ohm calculation stuff, I've got 200 feet of wire.... plus or minus 150 feet."_

you're also measuring your own resistance if you hold the leads. so you have two parallel resistances, the math may be complicated so better to just use alligator clips.

The most gangster shit is buying yourself a broom and cleaning up your own mess. (Of all the electricians I've known in my years in construction, I've only met 1 that cleans up after himself 😂)

I usually write on the roll how much I took and subtract it from the original lenght

AS a retired tradesman I can tell you the old guys have all the tricks they don't teach you in school.

Yep that's real talk was I was thought that by a young fella myself, one of the biggest reasons we need to share the wealth. Otherwise the knowledge is wasted. It gets lost. Definitely one of the reasons why we need to stay in touch with the older generation it is not a waste of time. It is a learning experience. They have so many stories to tell and so much knowledge to share if we would just slow down and pay attention, their knowledge is priceless

Sjeezz, been electrician for long? This is the most basic knowledge you learn at school. So proud... 😂😂😂

Couple of things to consider here: 1) The graph you were showing specifies resistance/distance at 75 degC and since the copper resistance is dependant on temperature by the following equation: R = Rref*(1+a*(T-Tref)), a = 0.00393 Which means that the resistance you are measuring, lets use the ~1Ohm measurement as an example, at what I would assume is room temp = 25 degC means that the resistance of this wire at 75 degC. R = 1Ohm*(1+0.00393(75-25)) = 1.1965 Ohm This would mean that your measurement corresponds to L = 1.1965 Ohm * 500 feet/Ohm = 598.25 feet ~ 600 feet. 2) Typically multimeters are not good for measuring low resistances this has to do with the low supply current combined with a two lead measurement approach which does not account for the resistance in your measuring lead. Let me give you an example with the ~1Ohm measurement. It looks like you are using a Klein MM400 multimeter which in the measurement range 0-400 Ohms has an accuracy of +-2% + 5 digits which means the actual resistance is anywhere between 0.48 ohms and 1.52. If I was to use this directly with the resistance/distance figure you gave, even without accounting for the incorrect temperature, this would mean the length is anywhere from 240 feet to 760 feet. Which makes the measurement almost useless. If you want to use this method to estimate the length of cable I would suggest you connect a DC power supply capable of providing a couple of amps, set the current control to a relatively high value (2-10A depending on wire guage) and then using a multimeter connected in parallel measure the voltage drop over the entire cable. Then compared this to a resistance/distance value for the temperature you are testing at or calculate the equivalent resistance at the temperature of the resistance/distance value you are using. 3) There are other factors of error like varying resistance within the cable due to factors like changes in conductor cross section etc.

It’s times like this where i NEED the bookmark to “My Favorites” button. I watched it 5 times in hopes of remembering it for the future.

Some call it gangster shit, some call it science. The old man who found it 200 years ago was called Georg Ohm.

Valuable info. 2-ohms per 1000ft & finding with a device's value to determine the length in a remaining reel made it simple. Thx ✌🙏🙏

Remember to make sure your meter is accurate enough for these kinds measurements. This should not be assumed. Ton of cheap meters are way off with small resistance measurements.

I worked with a retired electrician at my dads place. He showed that to me one day. Pretty neat! Miss you Jerry. Rip.

Another trick is to not hold both ur tumbs on the measure pins to avoid parallell resistance true ur body which actually lowers ur measurement giving you a false range of the actual spool.

“From an old man” the elderly also got the secrets.

It’s more accurate if you don’t add your body in parallel with the circuit. You can hold one end of the wire with the test lead, but the other end you want to wrap the wire around the test lead and then make sure your not touching it. Since your hand to hand resistance is significantly higher than that of the spool of wire, it shouldn’t change the value much, but it does affect it. Resistors in parallel: RT = 1 / (1/R1 )+(1/R2) + … (so on) The resulting resistance will never be greater than that of the lowest resistor in the parallel chain. That is why it doesn’t matter a whole lot if your in the circuit in this example because the spool of wire has an insanely low resistance compared to you. It’s just good practice to remove yourself from the equation because depending on the value of the resistor (spool of wire in this example) that your measuring, your body resistance can make a huge impact.

Now you’re the old man passing it down too me! All jokes aside, I never thought I’d watch a short with LEGITIMATE information.

The realest gangster electrical trick is stealing those partials out your truck and selling for scrap

this is actually a super useful trick that ill keep in my head from now on

I love how you went and added your body's resistance in parallel 😂

You need a milliohm meter. Your example with 0.4 ohms ignored the fact that if you put your meter leads together you read 0.3 ohms. As long as you're ok with being off by a few hundred feet, have at it

"Buys 200 feet of copper wire, get sold copper coated aluminum wire, uses trick, house burns down." 😂

Going to send this to all my Electrical Inspector friends. i do Structural and it's cool to me. They will love it.

Most gangsta shit ever would be teaching an electrician how to cut sheetrock without using just his hammer.

similarly for any auto or diesel technicians, the milivolt selection on your multimeter and a trusty chart you can find online that converts fuse amp rating voltage drops to miliamps, you can find which circuit is the culprit to an out-of-spec parasitic load by checking the milivolt drop across a fuse on a fuse panel or box

So glad I found this channel, apprentice lineman and finding your videos explaining a lot of my applied knowledge and helps me better understand everything. And they make me want to learn more. Keep it up boss your doing great

The most gangster shit is going in my glove box and grabbing the wire extender.

The resistance per foot will be slightly different between OFC (Oxygen Free Copper) and CCA (Copper Clad Aluminum) also, be sure you're testing clean copper (not tarnished). either sand clean or cut to expose fresh wire.

Damn dude you're a baller! So glad I randomly found this channel

Most gangster shit is running a backfeed while grilling during a hurricane gloating to your neighbors.😎

When he took out the chart table i was like : Daaaaammm thats gangsta!!

This is good stuff. I went to an estate sale the other day that had a whole bunch of roles of wire. My thought was wondering how much wire was on the used roles. So I passed them up. Note to self: carry multi meter in car at all times.

Most gangster shit would be seeing an electrician use a broom and clean up after themselves 😉 Edit: Damn you can tell who the sensitive electrician are in here

Oh wow...an electrician actually learned about electricity. So proud 😂

I feel like this is basic electrical knowledge that I learned in highschool physics class.

Gangsta until you are 4 inches short as you finish your project and all the hardware stores are closed

Read the numbers written on the wire sheath. They label the wire with footage marks, and numbers. This way you can just take a quick look and know what you have left.

Actually the most gangsta electrical trick is using broom and a bin when your finished 🤯

The most gangster thing is unravelling the roll, and getting the tape measure out.

Damn this was the most helpful KZfaq short I’ve ever seen. Great job!

I don’t do electrical work, but I feel like I’ll need this knowledge eventually.

Brilliant! I install under tile heating cables and ohms are part of the process! Didn’t know it would work with certain wire being copper or aluminum…Thanks

NOT EXACTLY, R is a function of Temperature, at room temperature you may get that reading, but as soon as E is applied, I goes up, THATS WHY THAT TABLE SAYS AT 75 degrees CELSIUS, you're sitting there at room temp which is only 21 degrees C. put that T90 through EMT with 600V applied and watch the R go up. LEARN THE AMPACITY of a conductor, that gives you the true value. not this gibberish.

Don't forget to short the probes so you can subtract the internal resistance of the meter.

I'm gonna need another gangster trick to show how to fish out the opposite end of the wire from inside of the roll.

😂😂 that is a new one for me you was right that is one of the most gangster electrical tricks I’ve ever seen

my brain is too smooth for this

My man just measured how tall he was with both his thumbs on those leads.

Awesome tip Dustin, numbers are on spot. 0.9 equal to 450ft, 1.0 equal to 500ft. Love it!

Gets to job site, pulls wire, 15 feet short because physics 😂

in electrical shop back in the late seventies we had to repair our plug fuses when we messed up in our circuits...lol. Using those tables and motor wire. lol this is a great trick...thanks for sharing

The resolution of the multimeter is not enough. You are having nearly ±100ft tolerance or more with a regular multimeter. Low resistance tests are performed with higher current for this reason. Regular multimeters pass too little current to measure accurately. Even some dirt in the dial can throw your readings off by hundres of feets. Be sure to "rel" the multimeter if it has the option. Otherwise read the reading with the probes shorted and then reading the reading with the probes on the wire and then minus the resistance of probes.

The only thing gangsta about electricians is how you get everyone else to clean up your mess 😂

That’s preschool calculations for electrical engineers 😂

This is mighty complicated math for most of the electricians I've known.

Multimeters are bad with low resistances. You get better results with continuity mode of installation tester. Basic multimeters measure resistance usually at about 1 mA, when installation testers do 200-250 mA. And installation testers have ways to zero out your test leads. With thicker wires I have used constant current source at couple amps and measured voltage drop with multimeter to get bit more precision.

Should verify your meter is actually accurate at this point and also measure the leads alone first to see the offset.

Your body has resistance so test without touching leads to fingers. Many multimeters will read greater than 0 ohms when shorted. As a Radio and SATCOM tech I also used a Simpson 260. That meter could be zero'ed and calibrated for greater accuracy on low resistance. A spool of wire is a giant induction coil. Steel benches, UV lamps, close proximity to AC outlet and many other factors can influence the readings.

My most gangster shit was turning my outside receptacles to 240 when my neighbor kept plugging in when he didnt ask

"We're been living most our lives wiring up a gangsta's paradise."

He should have first put both test leads together and push the REL button to remove their resistance which normally is 0.2-0.3(Ohm).

I have that same multimeter, I love that thing. I've owned multiple flukes and this remains to be my favorite meter so far.

Everyone gangsta until you try it on a transformer

Make sure that you're not touching at least one l lead on your meter, or you'll be measuring your body's resistance in parallel to the wire spool. Won't change much, but you're measuring a small resistance value. Good tip, though.

That’s physics. And the table is at 75°C. Resistance is lower at 25°C.

if i had been given access to whatever that book is id have learned more in a few days than i did in four months of electrical engineering training

No way. No more trying to find if there are feet markings. Or manually counting every foot mark. Thank you! Too cool.

Works, but I wouldn't trust the multimeter's accuracy too much for that low resistance values. Tip: to measure really low resistance fairly precise, hook up a lab power supply to the cable and set it to a constant current (not voltage) of 1 amp. The voltage reading you get equals your resistance.

Right on time for my internship (electrical engineer) and apprenticeship (electrician) Edit: Sadly, my school only teach theories. There's a separate institution to learn practical skills (which is as expensive as college in 1 year). Hence, why I just take apprenticeship

Whats more gangster is knowing how much is left on the spool just by looking at it

The most underrated video ever!!! Thanks 🙏

I mostly spend 50% of my time troubleshooting shorts to ground on Fire Alarm Cable. I have a whole scenario of distances in my head like 0.6 Ohms to ground equals around 50'-100' away on 16 awg.

Cool !! .. I think it would be close enough for truck stock, but since your doing it in the shop anyway, just use a milliohm meter with Kelvin clamps and compensate for ambient temperature. An actual wire length meter is basically the same setup with some preset wire specs onboard. These two methods are more expensive, but extremely accurate for checking warehouse stock. 👍

1974: A thing on an electrician’s exam 2024: Gangsta shit

I'm not even an electrician and even I think that gangster AF

Adding body resistance with parallel is called the real gangster shit

My lineman buddy sent me your TikTok the other day, good shit Dustin

The most gangster electrical trick is sticking your finger in the socket YEEOOOOWWCCHHHH

Wow, I didn’t know there was anything gangster about being electrician😂😂😂

When you clasp the the ends of the meter leads like that, you're creating a parallel path through your body and getting a lower resistance reading than if you were just measuring the wire by itself.

Meanwhile, network cable has the measurements printed on the jacket. :-)

The most gangster shit is eye ballin it and being correct within a foot.

I was taught this in the first week of my training, this is a basic part of electrical testing in the UK

I'm pretty sure the "most gangster way" to tell how much wire you have, would be walking into a hardware store, pulling an entire new reel of wire, and walking out with it. You know exactly how much you have. Now you just gotta bug out before the cops arrive.

Heck yea. I like the code refrence Chapter 9 Table 8. I have learned alot from you keep it up

Im out here learning shit I'll never use but I'll remember it longer than the shit my wife tells me

We would do TDR, Time domain reflectometry , you send a pulse down the wire and the machine will measure how long it takes to see the reflection and that tells the distance. The phone company uses it to find breaks in underground cables sometimes.
