changing 277 volt ballasts, electrical

- Always use proper safety equipment when working on live circuits. when at all possible turn the power off. So I thought I had a couple bad ballasts, I didn't check power first because i change so many that 95% of the time that is the issue. Turns out it was something different.
About a year ago i was changing one of these types in a factory. I unfortunately was trained wrong and was hooked up to a hot wire for roughly 8 secs before i blacked out and the weight of my body caused me to break the connection. I still suffer from issues in my muscles as well as shoulder and neck pain. Always work safe and always double check your safety.
Work safe and cut power when possible. 277 will kill you quickly
Good ideas- break one of tabs off. Will help my maintenance crew
great job , good luck 🥰
And you shape surfboards too!
I do, but I am a better electrician....maybe??
LED????
This video is a few years old and since then all the lights have been upgraded to ballast free LED fixtures
Are there 58W T8 1500mm lamps?
13 watt t8 4 foot lamps
@@paulalbus491 We have 36Watt this size lamps in Russia at factory. Inductive ballasts are 220-240 Volt. And starters 36-80 Watt.
@@sergeiparkhomenko5542 wow! those are huge wattage. LED lamps are really taking over in U.S. i have not changed a ballast in over a year. now I just by pass the ballast and wire the lamp sockets direct. the LED lamps are rated for 100 volts to 280 volts they are so much brighter, and last years longer. I used to have a video on upgrading those to LED but didn't get a lot of views so I deleted it. I will see if I still have and and re post it.
@@paulalbus491 I agree fluorescent 36 Watt lamps are huge wattage. But there is no possibility to replace all fluorescent fixtures for new LED - fixtures. In fact we try to use 9,18 or 24 Watt 220-240 Volt LED- lamps in old fluorescent fixtures by Your method (if lamp sockets are not broken). If broken, we install 32 or 45 Watt 160-260 Volt alluminium LED- fixtures. Power supply sistem in Russia is 380/220 Volt that is nominal. Usually we have 380-420 Volt (three phases for motors, heaters e.t.c) and 220-240 Volt (for lighting, recepticls).
Could of used a 4 lamp ballast ! Lol
I could have, but the building manager wants them to continue to be switched separately, despite the building automation controlling therm. Don't ask me dude, I'm just a solider in his army and do what he wants.
I have put 4 lamp ballasts in without his knowledge In a pinch.
See this ballast its covered in PCB's. I'm going to toss it to you and DO NOT drop it.
pcb ballast havent been used in 40 years....but u may come accross one in an old warehouse..
@@SlayerHawkX I was tasked with removing them from several facilities. Some jobs were written off as complete but never were and were left to be found decades later. Ever see a pcb plume dust from a fixture installed in the 1960’s? I guess you haven’t. One guy said don't talk about it another guy warned me they sent me to get sick cleaning up after them. I couldn't of imagined how sick I was going to get but I knew if I did I earned the right to speak up about it. Last time I handled a pcb ballast was about 2010 for the DCR.
@CrazyEyesGaming been doing this 25 years...iv seen it all...20 years ago, id have the oils all over me
@@SlayerHawkX Some of it’s hard to get off the skin isn’t it? The experience left me a bit aggravated is all. I went through a lot of hazardous work I had to refuse some of it. Heard nobodies going to look out for you but you a lot. In my research trying to understand why I was getting such horrible inflammation throughout my body I read about several kinds of pcb’s one having dioxin being especially nasty. Some chemicals were altered according to profitability of course. ‘We don’t pay you to be safe’ haha. You’d have to live it to believe it.
@CrazyEyesGaming ya..it was like stickum....1st thing recycling plants ask...how old are the ballst..lol
Just change them to led
Since that video, they have all been upgraded to L.E.D.
thats not how u do it..heh...took way to long.And the wiring?? ...how is it , there was a blk(120v)..red(277V).white neutral and grn( ground)on the fixture(power input).and u used both powers?..one ballast hotwire on a disconnect with no neutral connected to the 120..then the other disconnect u had the hot and 2 neutrals on the 277...?..put both ballast on 1 disconnect..thats why they have four inserts..at 16:19...im floored..ima bet u figured that out and did a lil editing...blamming it was unhooked up top...the forgetting to turn camera on thing..lmao...ur boss mayb watching eh..
Well they were quick disconnects, and the inside lights were one 1 switch, and outside lites were on 1 switch, actually 2 different circuits. So you're actually wrong. 1 neutral because when building was built it was code to have 3 lighting circuits on 1 neutral, sorry grounded conductor, no such animal as a neutral, that's a trade term.
@Paul Albus ah..makes sence now then...i hate that...they should just do every other lite instead of maken lite half n half...i couldnt make since of the wiring at first..lol
@@SlayerHawkX plus the evidently ran out of 3 wire quick connects when they rebuilt from t-12 to t- 8 lamps so that makes it look weird also. But now they are all direct wire LED lamps.
@Paul Albus yup. We been doin those for over a year now...job security!!..lol...iv been to places we done 15 years ago..
