If you don't care about turning off other breakers, you can find any breaker very quickly by using a strategy that programmers call binary searching. First flip half the breakers in the house. Light off? It's in that half. Light on? In the other. Then take the half it's in and flip half of those. Repeat until you've found the breaker. If you have 40 breakers, flipping them all one by one will take 40 flips. Flipping them in this way will identify it in 6, maximum.

[@thinktank8286]

What an interesting practice! I'm curious as to how this is used in the programming world of work.

[@MichaelBarnathan]

@@thinktank8286 lots of ways, it's very handy! The most common usage is searching for a number in a sorted list. Even if the list is large, you can pull out the middle number and cut it in half repeatedly depending on whether it's greater or less than your target. The number of steps you need is the base 2 logarithm of the list size, much smaller than the size of the list itself. The principle is also used to partition data into "binary" trees (two branches at each node of the tree), where going down either branch cuts the problem in half, recursively

[@JL-uc7xp]

That is an interesting concept, but it’s not accurate to say 6 flips vs 40. You mean 6 “rounds” or groups of breakers operated. For example if you have 40 breakers, in the first round you flip 20, in the second round you flip 10, in the third round you flip 5, etc. So far 20 + 10 + 5 = 35 plus the last few rounds of 1-2 breakers each. Compare this to flipping all one by one. In both cases, you have to flip almost 40 breakers total (maximum if you are unlucky)… Or less if you are lucky. Right?

[@MichaelBarnathan]

@@JL-uc7xp that's true, but if you're working alone, that might be the difference between 6 trips back and forth to the panel and 40

[@chrisE815]

@@thinktank8286 it's used for searching. Say you have an ordered list of data, say customer names. If you want to find a specific customer, you can use this method to find the customer name dramatically faster than looking through the list sequentially

You're doing parenting correctly and they will have those memories for life. They have a great example of what a dad is supposed to be. Huge props to you (and the kiddos)!

[@SavageVoyageur]

And thats why you test the circuit after you turn off the breaker.

[@paulnevins]

I labeled every outlet and switch in my house with circuit number, amperage and if it was gfci and or afci. It has been very helpful through the years.

[@Jdw6848]

I ran into a breaker for an electric furnace that was off but the circuit was still live. Never assume the circuit is dead until you check with a meter

[@adammorgan9304]

So the breaker wasn’t off evidently. Always assume the power is on until you’ve tested otherwise.

[@pbarnrob]

Moved into a nineteen-fifties’ “starter home” ($US~15k) in ‘78, with a garage-bedroom conversion (obv. by a previous owner/helper) that popped a breaker reliably. Replaced that old Pushmatic breaker, found one that popped on the other phase. They had double-fed that loop from both strings of outlets !

[@dracula3811]

@@adammorgan9304 not true. I've seen a guy get shocked on a circuit while the breaker was off. Not a shared neutral either. We replaced the breaker and the problem went away.

I’ve seen multiple ways that the breaker is off but there’s still power to the device. Yes, there’s always an explanation, but that’s kinda the point. If you check for power before working, then you’re alive and healthy when you’re figuring out how the thing was wired.

[@warlock529]

Sometimes when I'm being lazy, I simply short the conductors together with pliers or something after turning off the breaker I think is the one. or before... 😮

[@ibeleaf]

they just write that for insurance purposes, the handle is most certainly insulated because i often work on 600 with mine, just gotta know where the spicy parts are and dont touch em

[@rupe53]

have done this chore many times over the years. One or two helpers, tops. If you are by yourself and don't have fancy tools / testers, just use a long extension cord and a radio turned up so you can hear it from the basement. Start with breakers off and when the radio comes on you go up and see which outlets are working via the long cord. This way you don't have to carry the radio around so much. Leaving light switches on will aid in finding those circuits along the way. Do the big appliances the same way... turn them on one at a time.

[@outlet6989]

Great idea. Ensure the radio plugs into the outlet and doesn't use backup batteries for power.

[@jaybird4095]

I've done this a few times. I first make a sketch of the floor plan, and note each receptacles location on the plan. While checking, I note the breaker number on the sketch. This ensures, I don't miss any, sometimes there is an odd breaker in the mix that you don't realize.

[@TunafishSmoothie]

For my house I created a spreadsheet that lists every single outlet, switch, etc. For example, "Bedroom 2 outlet on west wall", or "Bedroom 2 all outlets", followed by the breaker#. I keep this on the wall next to the panel (along with the basic floorplan from the purchase documents / appraisal). It has been quite useful over the years. Doing the investigation to set up the spreadsheet also helped us identify abandoned circuits (we also live in an old house) which we were able to remove from the panel. The spreadsheet detail also made the panel labeling much easier. Over the years this has saved us a lot of time.

[@bwbw1341]

We have the same thing. Our previous owner had identified each breaker. But recently we had an electrician came in to replace a lot of receptacles. We discovered that the original list was wrong. Our living room and master bedroom are connected to one 20amp circuit. Kind of disturbing, but that’s how the house was originally wired. Built in 1981.

[@intheshell35ify]

Then you can line the litter box with it.

[@tylerwatt12]

I need me some crazy lights 😂. I did this to my whole house. Every outlet. Took probably 4 hours. Also labeled the MWBC and gauge used. (There weren’t any handle ties). Put it all in an excel doc and printed it out. Very helpful for finding code violations and working on upgrades

[@Jeff-xy7fv]

Exactly! Every time I do a panel upgrade, labeling is not only a Code requirement to pass inspection, it also allows me to discover things that are wired to circuits they're not supposed to be wired to. I can use that to sell more work in the future.

A super nerdy way I did this recently was to use an IoTaWatt whole house monitoring system (the kind with the clip-on CT) and walk around the house with a load like a hair drier. Just flip on switches as you go into rooms to see the spike for lights and plug the hair drier into each outlet you want to test. Way fewer trips back to the panel since you can watch the graphs on a cellphone or similar

An excellent and informative video- subscribed. I just picked up a Klein ET450 circuit tracer kit as my home (built in 1978) could sure use some mapping out of the circuits. Nowhere near the complexity of dealing with sub-sub-subpanels as you had there, but definitely a couple of unique configurations to put it mildly. I know of two Edison (multiwire) circuits, one of them in the basement where they originally used the clothes washer receptacle device yoke to split it up... I corrected that fiasco a number of years ago. The other one on the main level is a REAL head-scratcher! A few others are puzzling to say the least.

Man... Just last week, I completed identifying all my circuits, deleted abandoned wiring as far back as my opened walls gave access to (then taped and labelled "ABANDONED"), tidied up wiring within the panel's gutters, then created a detailed (and date-stamped) panel schedule for my 30-space Square D panel in my 60s house. Since I was adding circuits, I decided to snip pieces of Romex insulation to also put labels on the wires at the breaker termination so that there's less guess work to do during servicing. After watching your video today, I feel good about having not missed a step. Thanks for documenting and sharing the master electrician's process! Also, working around 7 sub-panels must be extra time consuming... Glad you got quality help!

[@gregchambers6100]

Nice work everyone! I know you've done this Joel, at least by accident, but we've resorted to the Blue Flame Test (dead short) IDs and tests breaker! I understand why you chose not to mention it. We had a commercial building with multiple panels sharing circuits (color to color joined illegally in j boxes) all over the damned building. Iding the circuit, BUT, it was still hot at the open breaker, so my advice is to add the step of checking the terminal with the breaker OFF, just to make sure. YOU ROCK BROTHER!!!

[@mayorb3366]

Excellent video! I just ordered a Klein circuit tracer.

[@electricboyo]

I identify breakers connected to receptacles with a plug-in radio. I turn it up loud enough to be heard from the panel location. Then I flip breakers in the panel one by one until the radio goes off. I label receptacles with their associated breaker number. When a visible label isn’t desirable I put it behind the wall plate. For labels on the panel I use N-E-S-W plus room ID. A code hint I learned from this video is to label unused breakers with the word “spare.”

Here's a tip: Start with a floor plan of the house, or office, large enough of a print-out you can mark where each outlet and device is located, and their circuit number. It can also be helpful to indicate which switches go to which devices. With older homes you would be amazed at what is on a circuit: I found out, the hard way while installing shelves, outlets in my room, in the basement, are on the same circuit as the television in the living room, on the other side of the house!

Fortunately, these outlets are labeled as being GFCI protected.

[@corazontopangalive3905]

I second the floor plan! It can give a lot of insight, and also it's completely unambiguous. I got lucky with my current house- although it was built 30 years ago, the developers had created a brochure with floor plans for the various models, and someone had put it online! I was able to put the drawing into my CAD program, and with a couple of actual measurements, I could scale it to real size and trace over it, verifying actual dimensions as needed. Then I drew all of the circuits and numbered them to match the breaker numbers. It was kind of fun . . . and the information is very useful. Especially now since I am going to install an Emporia Energy Monitor and I need to know what is on each breaker!

On a whim I bought the circuit tracer at Harbor Freight. Other than the soft button that likes to get bumped ( i fixed it by adding a manual switch ) it does fairly well for somebody on a budget. The only downside other than the switch is that it can occasionally lock out on testing and give a false negative on all circuits, to remedy this just restart the thing and start over. the time saved getting things labeled will certainly make up for an extra 10 seconds running down all the breakers again. I have actually used it on an actual an fuse panel and had great success, on some older breaker types it is a little iffy.

Hi Joel, I’m enjoying your videos. Just noticed the dryer ducting on the wall. All the ells, I think I count 3 including the one at the back of the dryer, effectively add about 15’ per ell to the overall length of the ductwork. Like the flow of electricity, it adds resistance to the air flow creating lint buildup and blockage. I run a diagonal, smooth aluminum piece from the back of the dryer to the last ell. Just a suggestion.

[@sjpropertyservices3987]

A time consuming process, but one I recommend to all home owners. I recall doing this without help using a radio and running back and forth to the panel. Inalky buying a Klein circuit finder has been well worth the investment. Even with the circuit finder having a helper is a time saver. I now mark the circuit breaker # inside the receptacle or switch plate even when the panel has been properly labeled. Even with a panel properly labeled I sill use a receptacle or non contact tester to confirm power is off to an outlet before working on it. Learned this the hard way many years ago when working on a receptacle when I found the hard way it had been used as a junction box and had two live conductors. Fortunately just startled and not injured, but learned a valuable lesson.

small note; i've got that same klein circuit tracer and the plug in tester/transmitter is rated for 120v, if it gets 240v, all three lights appear to be on, so if you're tracing a 240v circuit you might want to alligator clip to one line and the neutral instead of both lines when possible. these circuit tracers can act weird occasionally as it is, you don't want to damage it and make it more uncertain

Just the other day I located the circuit that powered the coal-fired water boiler that hasn't been used in probably 6 or 7 decades. Of course, it was live. And the dishwasher was correctly labeled on one of the equally old fuse boxes ... someone had scratched "Dishwasher" in the outside of the fuse box case. It was easy to see once you're no more than 5 inches away from it. :)

I picked up the same Klein Circuit Breaker to confirm and label the panel in my house. Albeit my house is a single panel, but I wanted to take out the guess work while I was replacing all the old light switches and receptacles.

I had to swap out 2 panels out. 1 - 300amp and 1- 100amp. Nightmare!!! Rigid, pvc, 3 sump pumps. You get the point. After 2 days I had to come back to label the panel. Which wasn’t labeled to begin with.

Nice video. Many great comments below. I label the face of every box, outlet and fixture I work on with the breaker number using a Brother label maker label with white letters on clear tape for dark color plates, and black letters on clear tape for light color plates. Inexpensive, reasonably discrete and easy. Same stuff also used to label cords and cables for AV and IT equipment. Panel labeling is an art to be concise, unambiguous, and terse enough to fit the space in the directory. It can be difficult for catch-all circuits that have lights and receptacles scattered all over the place. A floor plan showing all the devices is a tremendous help both for maintenance and for remodeling. Watch out for multiwire branch circuits where the breakers are missing handle ties. Also never assume, always test, that when you open a disconnect or switch off a breaker that the power is actually off on all hot legs. Don't ask me how I know that.

Have you tried plugging in a bunch of wifi smart outlets and then just looking at the smart home app on your phone to see which ones go offline when you flip the breaker?

Also suspicious on the loadcenter directory is the CIRCUIT RELOCATION of the DISHWASHER from panelboard position #23 to position #30 with the RANGE HOOD. If that HOOD is cord-connected, per NEC® 422.16(B)(4) list item 3 the hood’s receptacle outlet MUST be on an INDIVIDUAL BRANCH CIRCUIT, i.e., the DISHWASHER CANNOT BE ADDED; it won’t be an INDIVIDUAL BRANCH CIRCUIT anymore. - former CMP-17 Principal, present CMP-15 Principal, present CMP-2 Alternate.

One son and cell phones in a 1771 /early 1800's house with apartments added in 1970. The joke became, if it's not on the other circuits, it's on #24. One main panel for of the main house, one panel (in the apartment cellar) for the main house kitchen and 4 panels in the apartment cellar (one for each apartment).

[@imark7777777]

I was helping somebody who is having difficulty seeing and they needed the breakers labeled. The brand new apartment that they moved into was nice enough to print out a sheet identifying what was what however they failed horribly on distinct there's at least two things that registers as hot water heater and more circuits than what I could identify Outlets of and this is only an 12 breaker panel. I was simply able to enlarge what was there but what really needed to happen was re-identification into identifiable names with no ambiguity.

Joel better order up 8 more service vans...cuz those kids are ready to head to the job site!

The forklift scrapped a 4x4 double receptacle 115VAC box off the stanchion. Still live, not labeled. The last time I had this problem I did one breaker at a time and shut down the sales department computers in the course of finding the one I needed. This time I took an insulated solid 10ga wire and crossed the contacts, not recommended. Boss caught me, chew began, I asked him should I shut down the sales department again? The breaker I wanted was tripped as I expected. Locked out and he left me to effect the repairs. Proper labeling would have made this unnecessary. Now I have a GFIC tester, works for me in these kinds of casualties.

I’m a master, and have my ICC electrical inspector license. I would only add to your descriptions a caveat that you should follow the manufacturer nameplate on breaker/fuse and wire size. Yes, this will make grown men scream and cry, but there are numerous times when the nameplate calls for something like “20 amp wire and 40 amp breaker”. This breaks all the rules in my head, except it’s correct. Follow the manufacturer’s instructions.

[@andrewwhite3793]

In the UK its standard to label fuse boxes . Another point is you will not catch a UK or European Spark without insulated screwdrivers. So waving an uninsulated screwdriver in a fusebox is a no no

[@jjjacer]

for my panel as im in a mobile home, i made a drawing of the home with all the outlets marked with a number then i had a table with all the breakers with those numbers. so not only is the breaker panel labeled i have a visual sheet to where which outlet each breaker controls

[@cfgdr3]

Love it

Lol, sounds like you got a few electricians on board.
