- This was a service call on a set of reach in freezers that were not working at all, I found the system had a bad circuit breaker and a shorted out drain line heater.

Today was my first day brazing thanks to your videos I already knew how to do it!
Good fix, as always. FYI, since that was an actual double pole breaker and it says on the side it said "common trip" you need to close both switches at the same time. Since the tie bar was missing and you were only closing one pole at a time you could hear it trip free, that's why it was easy and didn't sound right. Once you pulled it out and opened and closed both poles together it sounded much different, more solid. But, regardless, the breaker was cracked so good call on replacing it. Also not a bad idea to exercise the breakers like you did, but in an old panel like that make sure you're not doing it on a Friday night when the supply houses are closed. I am sure you have shut off a breaker to only have it not close again, I know you know this, just putting that out there for the next guy.
Cutler- Hammer Type CH are common in FL... sold at HD, Lowe's etc.
whoever used terminals on the ends of the wire should be strangled... I've repaired many panel fires from just that kind of stupidity, it generates more heat from poor contact than just putting it directly under the screw for which it was intended.
I love that I've watched enough of your videos to think "hey that rack looks familiar" at the beginning of the video, right before you said you'd been there before.
Great video.... fan cycle and defrost term switches bypassed in the cooks freezer evap.. pencil drain line heater killed the breaker...
We also have to call an electrician in pa! Doesnt mean I haven't replaced breakers for a good customer!
Im in the HVAC Union in NYC, technically we have to call an electrician because it's on the panel.
Same here I'm a union pipefitter in Chicago anything before the disconnect is an electricians work.
One reason unions are going the way of the dinosaur.
I cant believe United didnt have that heater for you. They usually always stock that cool stuff. Nice vid!
Ch breakers are widely available even Lowe’s and home depot carries them, the older ch breakers are interchangeable with a new one, nice finds one so coil!
I had a main breaker fused together on 1 leg and I couldn’t turn off the power completely. Half the house was hot except 208 appliances. The home owner said at one time the service was struck by lightning. I packed my tools and left and they eventually replaced the service panel and lines to the pole. Set them back 4K. I see that sometimes in the field.
That was code back in the 80's to have the conduit as the ground. I always try to check the amps when I startup a suspect unit just to watch for high amps. I like that electrical shop with the old panels. That's a great idea.
Sorry, no ..
this is a Sub Panel, it has always required an insulated,isolated separate ground
@@embreesmith7613 And I do not believe liquid tite qualifies as a ground for anything. Always run a ground wire from box to box or box to connection when liquid tie is in use. Older codes allowed emt and rigid to be the ground.
@@tedgerstenslager2949 You, Sir are CORRECT :)
a grounding conductor is always required in steel liquid-tite
I love Western Enterprise, they have everything you need. Nice find and video 👍
Thanks bud
I have discovered in my travels that breakers can and do wear out. It's just a resettable fuse, but they can corrode over time......
Fun times. Love refrigeration calls
Hey Chris thanks for another good video 😀 (I'm also handling the Friday thing awhole lot better)
Those Cutler Hammer CH series panels have been around a long time. I know in my area I do have to special order those when I need them.
This 10:00 reminds me of Jurassic Park 1 scene turning stuff on at the electrical panel one by one.
another gr8 one chris. keep it coming buddy.
it puts the lotion on the skin or else it gets the hose again.
Also we have to deal with this issue constantly due to all of the historic bldgs. However we dont always have to deal with high occupancy bldgs. Like you have to in nyc.
Nation Circuit Breaker in Santa Fe Springs specializes in obsolete Circuit breakers and other electrical components. I have had to use them before
M&M circuit breakers in Rancho Cucamonga. Hard to find breakers, they saved me many times
Thanks for the info.
Anther good video like always thanks
I just came acrossed your channel last week. Really like your vidz so I subed.
Thanks bud
@@HVACRVIDEOS What I really like about your format is how you give a detailed explanation at the end of the video of what is going on.
Nice job brotha! 👍🏼 There are times where we do electricians work for our customers
Another good vid Bud ... Lol ... Much appreciated ...
Seal tight ground, 20amps or more needs a ground wire.
Looked like Liquidtight Metallic Flexible Conduit, not the Nonmetallic type so OG installer using the conduit as ground was GTG.
Seeing your ring hand in that panel made me wince lol 😂
I believe Chris wares a rubberized ring?
Yeah I wear a silicone wedding ring.
I figured by the color lol reflex response
Bad bus bar??? LOL.... Bad breaker, still love ya man
I hope everything grabbed a shot at the right time.
GOOD VIDEO ,, THENX
Our country has 415 vac between phases.
MEN Earth or ground wires keep the electrical grid at zero potential to earth.
(Multiple earth neutral systems.)
Otherwise you get stray voltages between buildings and metal objects.
Earth wires also provide alternative path to neutral busbar incase a live wire earths against the metal enclosure allowing the over current protection to operate.
Auckland NZ.
Nice 1 boss
Love Western, pulled me out of a jam many times
You are right, single phase sucks, 3 phase is best. That panel must have seen better days👋
If there equipment was 3 phase how much money they could save in energy in long run. Maybe when they change that crap out nice upgrade or selling point.
That breaker failed from prolonged overheating, you can tell by how the casing dried out and cracked.. that being the case I would’ve taken an amp reading to see what’s going on
a Neutral, is a current-carrying conductor
not a Ground, Sonny .. :)
that should be a 5-wire feed to that sub panel, it is not "service equipment"
It is the grounded conductor according the NEC and is bonded to the grounding conductor/grounding system at the service entrance load center.
@@embreesmith7613 techicaly you dont need a neutral if there is no 120V equipment.
Great 📹
While it is nice to pretty things up! Form does follow function!
Chris what safety glasses do you recommend and also gloves thanks
Great video Chris. Did you get a chest mount for the Go Pro?
I have a chest mount but I've never used it. In this video I used a head mount.
I have to laugh at all the comments about calling an an electrician. Changing, diagnosing a breaker is not brain surgery. Electrical work is a thousand times easier than HVAC.
Not when it comes to staying certified and keeping bureaucracy happy, but yes there is more work involved when it comes to the thought process in troubleshooting HVAC systems.
What insulated screwdrivers are you using? Looking to get a second set to build a rooftop bag and a bag for homes
why not just do a continuity test on the breaker when you took it out? with all that corrosion inside, it could have just had a really bad connection.. but nice job either way! half electrician.. half plumber... all HVAC?
Continuity will screw ya. Can be a totally different reading under load
I see your point, and agree. but you can always do continuity under load by hitting the bus and the input line.
rick w very true. I’ve been bitten a few times on appliances with pinched wires and stuff lol. Voltage never lies is my new lifestyle 😂
Just replace it, don’t waste any more time on it.
@@charlesmurphy1510 that's if you have the part on hand. If you have to run back to the shop or supply house to get it, testing doesn't seem longer to me
Nice work Chris ! I see that you're using GoPro ?
Yeah I still use my phone for most of the videos but sometimes I pull the go pro out for some footage
How often, after you've told a customer that you can't immediately source a part, does a customer say that they need the operating right now and how to you handle a customer that doesn't understand unavoidable delays?
Anything is possible if they want to pay, so we politely let them know the cost difference between doing it now and doing it later. They usually pick later
Bro thanks for all ur work and lessons, I have a quistion, how do you heat ur lunch? When ur out in the field, or you just buy food? I'm about to start working out doors, any advice?

@@HVACRVIDEOS thank you, cool, I guess I'll get this and the Walmart portable little stove, since I don't have an inverter yet in my van.
Can you show us how to wired up limit switch please thanks sir
Does your area allow you to work in a breaker panel? Technically in my area we aren't allowed to. Me personally, if I don't have power to the unit and resetting a breaker doesn't work its electrician time.
The OCD Electrician's apprentice in me is trying not to pass out.....plz ignore this but have to vent the OCD.. just change the panel it's not safe!! a 200 amp subpanel is only $100 at lowes and if you get the right style you can use the old breakers..... Sorry HAD to put that out there....i know it's not Chris' fault.... Mr. big picture would have changed it if he had found an excuse to justify it to the customer.
Hah. 3 phase 100a mainlug sub panel for 100?$
The panel is cheap but 4+ hours of labor on that job is no joke.
Why does a small reach in freezer, have a giant Tecumseh AWG4542EXN reciprocating compressor?
Dear Sir, this morning I worked on a Traulsen Freezer, it run short cycles. I replaced Start kids (Potential relay, run capacitor, start capacitor after found bad on run capacitor, potential relay, low to minimum rate of start Cap.. I checked Ohms on compressor 3 terminals seems good C to S = 4.7 Ohms; C to R = 1.9 Ohms and S to R = 6.7 Ohms . When restart, the Freezer operates in Short cycles as before. So what Can I blame to : compressor, Time clock, or temperature control.
Please explain. At 3:30... Their is a condensing unit with ducting going to it on one side. I've installed hundreds of rooftop units but the curb adapter routs the ductwork?
Are you allowed to get that deep into the breaker panel? Or is there a certain place where one as a Refrigeration tech has to call an electrician
Its what your comfortable with, this is tiny stuff. (Respect it) As a 35 yr. service tech more than half your problems will be electrical in this field.
No wire termination for flex wires?
You mentioned that breaker was off , I have found that those older Cutler hammer breakers tend to trip to the off postion, was that the case with your breaker ?
It's a very good possibility that it was tripped. The owner had tried to reset it before I got there so who knows how he found it.....
On all main p. Or sub. Go side to side n stand to one side not in front
Pencil Heater. First time I see one 🤓
Nice work chris! Hey is your merch available now for order?
So I haven't received samples yet, I realize they show up as available to order but you would be better off waiting until I have received them and verified that they look good. I am expecting to receive them next week
Sweet man thanks, I’ll check back next week!
I don't know about California but what you have there is a subpanel feeding those units they don't want a dedicated ground at the sub panel they only want the main pricipal bonded I believe that's how are electrical code is sounds crazy but there is sound reasoning behind it and I can't remember exactly what it is
Totally different issue. The neutral is not bonded to the ground bus at subpanels to avoid unbalanced current flowing across common metal surfaces or fault current to have to travel across the neutral during a fault event. An equipment grounding conductor should be taken to all equipment, especially with flexible conduit that may not be able to provide a proper path to ground.
Yes understood I couldn't remember exactly what I kept tucked away in my head👍
Interesting you have stranded wire going into the breaker panel - you don’t see that much!
sure you do. Everything above 8AWG or 6 comes stranded most of the time.
Did you get free lunch?
If I shut off the power AND I will be working on the lines, I put a sign over the breaker that I am working on it, so that nobody comes up with the clever idea to turn that breaker back on.
why not do a continuity test on the old breaker itself? those parts runs kills so much time in a day...
Why does something small like that have a giant Tecumseh reciprocating compressor?? That's a 30000 BTU air conditioner compressor
Elec chicken if i ever saw one...
👍👍👍

Oh wait..........nevermind
Man you post early lol
I scheduled them I'm actually on vacation for a family wedding right now. But typically I post them at 6am east coast time
What kind of van do you drive
Chevy express
HVACR VIDEOS Awesome those are one of the best vans out there
actually, 2 pole breakers need to be connected together as well
Installing wires back into the breaker without an electric wire ferrule? It's compulsory in europe.
Since most wire here is copper and most ferrules are aluminum, they should not actually be used because of corrosion due to electrolysis.
@@anthonycaron2265 that literary only counts if the connection gets wet. Plus, if the connection gets wet AND you dont use them, the changes are bigger that you short the circuit and cause bigger problems
Absolutely false. Look up electrolysis, before you have an opinion about it.
No requirement in the UK to have them.
@@anthonycaron2265 the ferrules over here in Eurpe are tinned copper.
👍 Great video. Tnx for sharing. I just Unfollowed the southern dude who starts his videos with a minute of advertising. And seems to think we want to see his spitting in a bottle as he talks. Goodbye Israel! Tnx for being a professional HVAC tech. 👌
since when did he spit in bottles??
What's his channel?
@@whitesheatingairappliancer7101 isrealhvac
Ok thank you. Have a good day.
Saw a guy get knock on his ass from messing with a neutral 🤕🤯
How many times has that ring gotten you zapped lol
It's a silicone wedding ring, I dont wear anything conductive
HVACR VIDEOS not trying to troll ya lol but thanks for the video they are always useful keep up the good work
No worries bud, thanks for watching! By the way my name is Chris
Safety ---Lock out tag out main breaker for that panel anybody could turn that breaker downstairs .In are state trade licensed we are allow from equipment to the main breaker then it's an electrical job. Really you don't have any electrical safety gear like gloves while inside 3 phase panel live .
The pain oooooo the pain..... I got shocked by 480 because the owner forgot I was working on the system. So she just turned it on even though I put red tape over it. She said she was sorry, she thought i had left. She has bad memory. The worst shock of my life, but I'm kind of glad it happened. I had a second chance to change my life around. Because now, I locked everything out and remove fuses. I will never take that chance again. To anybody out there that works on electricity everyday, it just takes one sick person to kill or maim you for life. Then under your insurance policy it states did you lock it out. They look at it after you died. NO!!!! So your policy does not apply. NOW YOUR FAMILY ARE SO DOOMED, NO LIFE INSURANCE. Look at your insurance fine print it's in there. The only Clause that you might be able to get around if you locked out a other source by accident.

That breaker was no good, whether it was good or not, both phases should shut off instantly if there is a a short, one on and one off would damage the equipment it's servicing.
Double pole, double throw, no service ground is not good.
No electrical panel should be on all at once old ornew
Here in europe it is not legal to connect a flexible power cord (containing many small copper wires) directly to a breaker. You have to use a clamp like you snipped off. Maybe code is different where you work.
One can allways use ferrules.
Not to speak out of turn, but you really should take your ring off before working near any electrical wiring or contacts, especially in that evaporator with the broken heater. Beyond the possibility of arc flash or a spot weld that you might not be able to break, you'll lose your finger if the heat cauterizes the blood vessels and nerves feeding it!
It's a silicone ring
I´m sorry but at 12:46 I thought you had found a strap on.
Ha that's funny!

You could save someone's life just for a few seconds. Most guys have had very mild shocks. They really do not understand how bad it can be. Imagine losing the use of your hands. Guys in this trade treat it like an art, and it is it's kind of fun. But so so dangerous. Water, oil, gas, etc........ all mixing with high voltage. The complacency bug will bite you. If you cannot see the disconnect from where you're working lock it out remove the wires or the fuses don't trust anybody even your partner. We all have bad days...............
