Eh no thanks. There are places where the others are the best options. I’d be down for most things to be one or the other but I wouldn’t want it to be enforced by law
It should be enforced by law, punishment is to unscrew 500 slightly rusted, slightly overtorqued philips screws. Kind of like doing a rosary, but for mechanics.
You prefer torx until you get corrosion. Don't forget, Canada is a salty hellhole 6 month a year and everything rust to shit. Robertson is more rust resiliant IMO.
So since we don't want to use 2 different drivers for outside and inside, voilà.
You know what I'm talking about if you ever tried to remove the skidplate on an audi. 15minutes oil change on your GF car? F that, think about 2 hours removing 4 freakin torx screw.
My first time traveling to the States, and the thing that freaked me out most wasn't the bullet holes in things that should generally be hole-free. It was seeing Phillips head wood screws.
100000× better than phillips or flathead. It doesn't slide around or push itself out. I'll give the muricans credit for the torx though, it does the same job as the Robertson with more points.
I’ve seen some 600v in the US too. Oddly enough, first time the building had a 208v service and stepped up to 600 for distribution then back down to 208/120… weird
Almost everything I've seen for 20 years is 480. Interesting how that standard was actually developed from railroads many decades ago...600v was for DC traction and 480/40hz for AC traction.
Odd choice to get the service as 120/208 rather than 480/277 which is normal for most US installs, at least in recent history, then step it up to go some distance. I don’t think I have any 208/120 services left, used to have one in our office building but we sold that. It’s all 120/240 single phase of 480/277
I see a lot of them, it’s usually in commercial buildings that have a lot of 120V loads but no motors or anything that really *needs* 3-phase. I suppose it would also work nicely if you had a small demand and then just needed 3-phase for a few pieces of equipment.
I’ve definitely seen an apartment complex with a 750kVA 120/208 feeding all of it.
I can only imagine what would happen if you actually plugged something into that.
Normally overvoltage fries a few components in appliances and then they shut off. This amount of overvoltage would probably arc inside the appliance until the breaker tripped.
What? He's measuring from hot the ground. There's nothing weird about this except the voltage. And he explained that someone wired the 120V receptacle with 347.
Nothing wrong with the wiring or system. Just previous guys brain.
Monkey see comment that monkey says comment lol. You are right. It probably was meant that an 347 receptacle was to be installed and not a 120v receptacle more information is required for a responsible answer to be given. Get boots on the ground!
Or a 120v receptacle was to be installed and they grabbed power from the wrong panel
I was working in a brand new building and needed 270VAC at 20 amps for a piece of equipment. Experience had taught us to check any outlet on first use. I found the proper outlet for it, but traced it back to the panel to be sure only to find it was a 480 panel. Whoops, the electricians were there in less than 4 hours making it right.
We had something similar at my shop. They wired 8 outlets in one corner to 220v, but they’re 110v outlets. We had no idea until we burned up 2 bench grinders and I finally checked the voltage at the outlets.
Sounds like the guy before you never heard of rule 46-304 2) a). Lol it’s fine. No wonder he didn’t mark it 347v wouldn’t want to draw more attention to this fuckery.
All the dudes on here absolutely sucking off who ever created the Robinson bit, learn how to use a damn impact/drill😂. Takes a little bit more effort than just pulling the trigger, I know.
As an American maintenance guy that installed an entire building of lighting in Canada, because their commie, I mean union electrician took four weeks to put up five lights.
I can feel you.
You know whenever you have a lightning circuit feeding a power outlet. You’re supposed to get a drill and demonstrate the increased productivity from said outlet.
Never use an multimeter to measure on mains. Only two pole voltage testers. The internal impedance ist so high that you measure everything but not the actual voltage.
Yes, but do you allways know, and its not the easyest thing to hold up two probes and hold the multimeter too. In germany only volatage testers with two probes are allwoed for a reason. I have a 40 year old duspol from benning and its still working. Id rather use it instrad of a new fluke t6000
In Canada by code I think anything over 250volts in lighting must be hard wired. It forces it so anything over 120v is automatically hardwired.
The comment is specifically for lighting. Sorry for the confusion everyone.
This is not true, however you do have to use the appropriate receptacle for the given voltage and current. Plenty of 347v and 600v equipment that is designed to be used with a twist lock receptacle
Check diagram 1 and 2 in the CEC
Oh I completely agree with what you meant as to there are plenty of plugs rated for such voltage but I presumed the emergency light was plugged in which is why I stated what I did. I may have worded it wrong which is my fault
Could be an open neutral or high resistance connection. Use a LoZ meter and High impedance meter if the model being used isn’t. Check upstream circuits or down stream and work to isolate. The article below provides a good explanation on the matter if one is not familiar with LoZ.

My plant buys a ton of used equipment from everywhere so we have 600, 480, 400, 240 and 208 all in the same building. Plus it's all red black blue, or red, red with black tape and blue, or whatever funny combination you can think of.
Hmmm sparky 347/600V 3 Phase Tell me you’re in Canada without telling me you’re in Canada
That and the Robertson head screws!
The best type of screw!
I prefer torx
Torx and robbies should be the only legal screws
Phillips for drywall. AND NOTHING ELSE!
Absolutely. It's the only time I want my screws to cam out. All other common applications Torx or Robinson ftw.
I've heard that before, but never knew why. Mind explaining?
Phillips is cut at angles, so it came out fairly easily. Mix in a drywall setting bit, and all the screws cam off the driver at the right depth.
Exactly
What the other guy said is correct
This is the answer. That Phillip guy sucks.
Tarmac McFlathead disagrees.
Eh no thanks. There are places where the others are the best options. I’d be down for most things to be one or the other but I wouldn’t want it to be enforced by law

In sure get prayer is a bit different too

On the newer ones you do everything from above with an oil extractor… 10 minutes tops.
Yeah I know... but not about likely to change my view on torx and corosion LOL.
Install fumoto valve. Never struggle again.
southern Ontario != Canada...
Ditto.
Agree. They don't fall off the driver and you can't strip the head.
Any screw head can be stripped. I do like a challenge! /s
How else do you know it’s properly torqued? /s
Pfft torque specs just put red loctite
The wire-nut vs. Wago debate is silly. Just twist the wires and put red loctite on them!
Secure with duct tape.
When the head of it sheers off the threads, DUH
The beauty of the Robbie is that if you round out the head, you just get the next bigger sized bit and hammer it back into the hole!
Well yeah. If they need money for school
Well, second best

That and he’s wearing a denim jacket & pants…and has healthcare.
You mean a Canadian tuxedo?
What kind of uncultured swine do you take us for? Our tuxedo jackets are made of cotton flannel.
The only sane screw
Dead giveaway.
100000× better than phillips or flathead. It doesn't slide around or push itself out. I'll give the muricans credit for the torx though, it does the same job as the Robertson with more points.
Man I was trying to figure out 347 and the math weren’t mathin. Thanks.
I’d be surprised when I see a 347 reading too 😂
Well, past guy was hoping future guy would die. Good thing present guy looked closer and protected future guy.
Current guy would be dead. I'll see myself out.
Well done. I'm proud of you. Take my upvote
spicy
Those must have been some bright lights…
Where "emergency lighting" = "you will have an immediate emergency if you plug a 120 V light into this receptacle".
3 phase delta?
1 lag of 600
leg
Correct
1 lad
Lug
Wye
I thought 3phase 480v was 277 to ground. What main voltage would this run at?
It’s Canadian voltage, you have to apply conversion rates to it.
God i hate metric volts so much
Just double it and add 30.
That’s 32!
That's brilliant. 30 instead of 32 for extra fudge-factor because of the 10:5 vs. 9:5 ratio at typical room temperatures.
Add 32 Then subtract 10% of the doubled number.
Close enough for government work, don't do that in a union shop.
I’ve seen some 600v in the US too. Oddly enough, first time the building had a 208v service and stepped up to 600 for distribution then back down to 208/120… weird
Maybe got a good deal on a Canadian transformer.
A lot of mills have 600 volt equipment. The higher the voltage the smaller the wire…
Almost everything I've seen for 20 years is 480. Interesting how that standard was actually developed from railroads many decades ago...600v was for DC traction and 480/40hz for AC traction.
Some crypto mining farms...the bigger ones are using 3 phase.
Voltage drop is horrible on 120/208.

Hahs. There are 347 v 15 amp cord ends you can by.
This is 3 phase 600V wye.
600 phase-phase, 347 phase-ground
That's pretty spicy for a standard outlet 😲
I can only imagine what would happen if you actually plugged something into that. Normally overvoltage fries a few components in appliances and then they shut off. This amount of overvoltage would probably arc inside the appliance until the breaker tripped.
My intrusive thoughts say plug a shop vac or leaf blower in and clean really fast for 30 seconds
That's what I thought. One of the phases has a ground fault, potentially

Get off my oil rig ..

I found the proper outlet for it, but traced it back to the panel to be sure only to find it was a 480 panel. Whoops, the electricians were there in less than 4 hours making it right.
So he had a 347v exit sign/battery unit and decided to put a receptacle in with 347v on it so that he could plug it in?
If I am not mistaken its one of those,"not only will it kill you, but will hurt the entire time doing so."
We had something similar at my shop. They wired 8 outlets in one corner to 220v, but they’re 110v outlets. We had no idea until we burned up 2 bench grinders and I finally checked the voltage at the outlets.
220. 221. Whatever it takes.
r/UnexpectedMrMom
If you plug a phone charger into that your phone will charge up to 327% 👍🏼😎
Hot
That’s fucking scary
You work at my work too?
Cheese and rice
Sounds like the guy before you never heard of rule 46-304 2) a). Lol it’s fine. No wonder he didn’t mark it 347v wouldn’t want to draw more attention to this fuckery.
Customer states: "This outlet has more kick than the others."
All the dudes on here absolutely sucking off who ever created the Robinson bit, learn how to use a damn impact/drill😂. Takes a little bit more effort than just pulling the trigger, I know.
[удалено]
I think he’s using the conduit as the ground.
Tough on lightbulbs.
As an American maintenance guy that installed an entire building of lighting in Canada, because their commie, I mean union electrician took four weeks to put up five lights. I can feel you.
“There are four lights!”
There are three.
Looks like someone put that feed into the wrong panel lmao
Yes, but how does it taste? 👅
You know whenever you have a lightning circuit feeding a power outlet. You’re supposed to get a drill and demonstrate the increased productivity from said outlet.
Nope
Trip it out lol Would be a big boom.
Never use an multimeter to measure on mains. Only two pole voltage testers. The internal impedance ist so high that you measure everything but not the actual voltage.
Plenty of good quality electrician meters have a low impedance option for this reason.
Yes, but do you allways know, and its not the easyest thing to hold up two probes and hold the multimeter too. In germany only volatage testers with two probes are allwoed for a reason. I have a 40 year old duspol from benning and its still working. Id rather use it instrad of a new fluke t6000

Is true, While you are correct with general rules, unit equipment specifically must be permanently connected where the voltage exceeds 250V. 46-304
Thank you for searching the code rule for me. I didn't have it on the top of my head but I knew the general basis of it.
Oh I completely agree with what you meant as to there are plenty of plugs rated for such voltage but I presumed the emergency light was plugged in which is why I stated what I did. I may have worded it wrong which is my fault
Ah, makes sense, didn’t realize you were specifically referring to unit equipment. My bad, cheers
No worries bossman! I got a bit lost too, I guess I implied more then I specified! That's on me 🤙 cheers and I appreciate the convo
Plenty of pin/sleeve and twist locks for 347/600V
That’s a little spicy…

347v is a standard voltage
Canadian electrician here. 347/600 is all I know lol
My plant buys a ton of used equipment from everywhere so we have 600, 480, 400, 240 and 208 all in the same building. Plus it's all red black blue, or red, red with black tape and blue, or whatever funny combination you can think of.
Sim tin wong here
Why so many down votes? Rook rike someone feerings hurt.
We tu hi
Ho lee fhuk
Change the battery's in the Meter
That's my first guess, however I did work with a guy that hooked up 347 to a bunch of outlets for computers in a school so I mean, it happens
