How To Work on LIVE CIRCUITS - Replacing Circuit Breakers in Old ZINSCO Panel

There are many old-school breakers out there still working today, even though their companies have shut down, and these materials have been outlawed for safety reasons. Many of these terrible breakers...are in my house currently. So today we swap them out, and talk about WORKING ON LIVE CIRCUITS SAFELY.

Connecticut Electric reached out to me about a year ago and we sat down and did an episode together talking about many of the products they offer. They manufacture brand new breakers for old legacy electrical systems like Federal Pacific, Zinsco, Wadesworth, Pushmatic, Challenger, and Murray.
When I told them I have an old Zinsco panel they asked me to snap a picture of all of the breakers and they offered to send me all new replacement breakers so I could test out their equipment. I happily agreed and thought it would be a great opportunity to test out my new GoPro 9 in the process. Many of you have asked that I strap on a GoPro and work so you can see first hand how I work. So I went and bought one so I could replace all my breakers.
I found, in the process, that one of my busses was damaged, and it was the spot on the bus where the existing 100 amp main breaker attaches. You can tell that there's been some heating issues over the years and when I tried putting the new 100 amp breaker in it's place it gave me a lot of trouble. But that's not a flaw in the breaker, it's a flaw in the bus. All of the other breakers went in just fine and now I have a practically new panel...except that I'm going to be ripping it all down and replacing it soon lol. That damaged bus makes me a little leery, even though I haven't had any issues with it in the past.
Once I got all of the new breakers in I began working on the live main breaker. I didn't have the luxury of the power being disconnected on this one, so I put on hot gloves and a face shield because of the environment I was working in. I don't recommend working on live wires if you don't have to. It's extremely dangerous, even when you're fully aware and paying attention. But every once in awhile you do need to work on live circuits, and there are companies that make PPE just for the occasion.
There are full flash suits that can be worn, however I chose not to wear them in this situation. I have many years of experience in this trade, I've worked on live circuits for years so I used the amount of PPE that I wanted to for the situation. This is also my own home, my own company, my insurance, so it was my liability to work with the level of PPE I did. Some would say I shouldn't have bothered wearing any at all, others would say I should have had the full suit on. Every electrician is the smartest electrician on the planet, so take what they say with a grain of salt. Just be careful working on live circuits. Make sure you wear proper PPE (information can be found in NFPA 70E), and don't do this kind of work unless you are a licensed and insured electrician, or are under the direct supervision of one.

[@apituraga9488]

Been an Electrician for 20 years and never worn insulated gloves... until last week when I opened a 415volts 200amps DB, I looked at the crowded wires and I just felt I need gloves on. Have to delay the job for about and hour when I hunt around for gloves... something in my guts just gave the feeling that something bad is going to happen if I don't take care. Sometimes when you get more experience, you can begin to just 'smell' the risks... and it begins with testing the circuits with multimeters over and over and over again. Regardless of experiences, we should always trust the meters.

[@garbo8962]

Hope you send gloves out every 6 month to be tested. Each sparky thetefore needs 2 pairs of gloves. We rolled rubber gloves up to check for leaks before each use. In summer always wore thin white gloves inside ofvrubber gloves to absorb sweat.

DIYer here. You have no idea how valuable videos like this are--I only wish they had been available when I owned my home and often DIMS. That house (wired with fabric covered 14ga) started out with a ZINSCO panel; had to replace a breaker once with a modern upgrade, which was nice but pricey ($20 back in the 90s; regular breakers were $5 or $6, as I recall). A couple of years later, I was able to have the 100 amp service upgraded to a 200 amp Siemens. Watching the pro do that was a great education--although I still get shivers when I remember him replacing the live service drop cable down from the pole--in a light rain. He was an old guy, which to me means he had survived his mistakes--better than any license or certification in my book. Key tip: replace the wires AFTER pulling the breaker. [smacks forehead]. How did I not figure that out?] I noticed you clipping a couple of wires with excess exposed conductors. What is the deal with guys baring so much of the conductors? I see that on a lot of outlets and switches I replace.

@Thomas Heydrick For me, the hype for Leviton panels have worn off. I'm not impressed the main lugs are smaller than most other panels, barely accepts 4/0 aluminum under normal 200 amp services. God help us if the service requires 250mcm for voltage drop, there is no way to change the lugs on leviton panels. For some strange reason, the lug for the neutral Buspar is larger than the phase lugs. WTF. I stick with EATON now (I used to swear by Murrey for the last 15 years) Good breakers, good panel guts, but God dam the cans are made of tin for residential grade.

Chances are nothing happens anyway, and I don’t believe there was a problem before NFPA 70E in fact I hate it. but I find the arc flash equipment with short sleeves so interesting.

[@doctordev97]

this is why, in my opinion, it should be required by code for there to be a dedicated separate shutoff switch between the meter and the panel, not just a main breaker. if you had a shutoff switch you wouldn't have to worry about doing hot work to swap the main breaker.

[@Vanilla_Icecream1231]

Thé problem with that is many places like here have a meter lock meaning the city requires you to pull a permit for a panel change, and if there was a disconnect it’s to easy for someone unauthorized to change the panel

[@doctordev97]

@@Vanilla_Icecream1231 Well, the shutoff would be after the meter, so changing the meter would be exactly the same regardless. Besides, making the meter itself safer to work on wouldn't be a bad thing imo, if someone does fuck with it illegally they should be fined, sure, but they don't deserve to accidentally turn themselves into a crispy critter.

My favorite panels are the Siemens and QO types with bolt in breakers. There's something exciting about putting a metal screwdriver directly onto a live bus.

I’m an electrician, and I love when other electricians act like changing breakers with the busbars off is like disarming a bomb LOL. You gotta be careful, but calm down….I had to change a panel the other day and the meter was seized in the meter box, so I had to both remove the SE cable from the old breaker/panel and then install the hot SE cable into the new panel and main breaker. Just relax (as in don’t build it up as some catastrophic event), use common sense, and have quality gloves and a way to safe off the ends. I find that most people I work with that have trouble working hot have trouble MOSTLY because they’ve built it up in their head as this monumental task. Think about everything he did here other than the main breaker. When it comes down to it, he was changing breakers on a dead busbar….easy. As long as you are smart with your movements, it’s the same as putting breakers in a completely dead panel. Then you get to the main breaker install, and that’s when you have to be smart and calm. If a main breaker that turned off has you hesitant to install breakers on the dead busbar, I venture to say you shouldn’t be doing panel work at all. He did a great job.

Now I don't think he is saying this is how to protect yourself when doing this kind of work. However. If I saw this work being performed on any of my sites or even as a contractor working a job, I would question if that electrical contractor or company deserves their certifications and qualifications if this is their Master Electrician. I've worked on my own circuits for my house hot and I wore at least CAT I Arc-flash hazard PPE. Use the right tools. Wear the right PPE. Or don't. But don't slack on those two things then make a video of yourself doing it and making yourself look an ass for public consumption. Is that harsh? Depends.

Can you please make a video explaining how to check for stray voltage and what we can do to fix something like this?

[@jfbeam]

W.r.t. to PPE, I would recommend keeping the PPE on until the main breaker is closed. There's no protection device between the panel and the meter, or visible anywhere upstream of the meter. So, if that breaker malfunctions, there might be 25kw there, and there might be 500kw. Earlier this year, we had a new 150A 480v breaker explode when closed, third time it had ever been cycled (by us, one would assume Eaton tested it) -- in a 1000A panel. The electrician was in full PPE, but he was still "pretty far from happy." (and yes, it's live work, that panel isn't so easy to power off.)

[@doodlez2439]

Been following for awhile and good content my man.

[@ElectricianU]

Thanks my dude!

[@elioselectric468]

Great demo. Most people need to understand that the voltage in residential is far less dangerous than industrial and commercial. The arc flash from this equipment(120, 208, 240 volts) is nothing compared to 277, 480, 600 and up. I try my best to pull the meter if possible, insulated tools prevents accidents big time and when in the danger zone or working space, everyone must keep out until I say so. Licensed experienced electricians only... when in doubt shut it down and test, test, test. Always treat equipment like it's live even when you know it's not

With any zinsco breaker you can reverse the bussing clips, (2 screws on back side) Doing so would have allowed you to avoid the damaged bussing section.

🇬🇾 Looking from Guyana, South America . I really appreciated your hands on info of how to handle/ hold live hot wires & not get shock. Safely first then you explained the rubber gloves as needed essential. Also you showed close ups of how to screw in the brakers with there safety tips. How to firstly isolate a hot main wires so as not to accedentially touch them while working. Basically you showed me how to work around my house and NOT get SHOCKED , providing i understood to use ( ALL ) the safety measures. Protect my hands with dry rubber gloves, rubber boots dry . It's best not to work with an active live main but if i must work , then employ these safety measures . Thanks . Close ups video shots are always better for learners continue to use them as they helps us to see & understand best . Thanks . I feel more confident now.

As a electrical design engineer since 1983, now retired, I can say that you are correct about Zinsco breakers. They sometimes just would not trip. Very dangerous. Most of the rest of the companies you named in the beginning of the video, just got bought out by other companies, not because their breakers were unsafe. I can't believe you said A phase and B phase. Respectfully, Kevin

I am also surprised at how often he describes the separate legs of the phase as different phases on single phase residential. In practice doesn’t cause any real issues, but is factually incorrect.

Depends on the transformer feeding the house. Alot of POCOs run 3ph OR 2ph in their distribution and use 2ph xfmrs to serve the house so the house is actually using 2 separate phases from the utility. Its 99% of the services in northern California.

I have observed to many near misses working on live electrical installation. One which l recall at a NHS UK hospital where l was called to the loss of all the kitchen electrical power, turned out to be an electrical contactor had unsuccessfully attempted to install a three phase circuit breaker in a live panel. It had tripped a 400 Amp. main supply C/B which had taken out all the kitchen power, the panel he was working on was now internally copper clad and he had suffered severe burns to his arms. The rule is always work on electrically isolated equipment when ever possible. Keep up the good work and stay safe.

Thanks for a VERY helpful video! I am only at 3:11 and already you helped me understand why my research is so difficult. I have a weak (mushy) 30 Amp breaker on a paired 240V circuit for my water heater. I see Sylvania on the breaker box and keep seeing Zinsco online when I see breakers that look like mine. They are expensive and seem to show up more on Ebay and mostly used or refurbished, especially when reasonably priced. Since the box is old (bringing some question to the age I am told from landlords of the house I am renting) and now I learn it is no longer approved for installation and the dangers of developing hot connections... a cause for pause. I will pull the cover and look at the bus connections for these 30A breakers and may inspect them all. Seems that Connecticut Electric, Inc. (thank you VERY much!) may have alternatives, hopefully that are plug and play replacements offering a safer install at least for however long I live here. Regardless of whether you make money at this I want you to know how helpful you have already been and may God reward your helping others!

One of the breaker contacts had completely vaporized, and there was carbon on the bus bar that they also filed smooth. Working great now, $100 learning experience, money well spent.
