[QUOTE=TippZ;37319151]where you from?[/QUOTE] Finland [editline]20th August 2012[/editline] [QUOTE=Reserved Parkin;37323644]Electricians make da big bucks, no?[/QUOTE] Depends where you are from ofcourse.
So I was droppin a dump, and my bathroom happens to be right above my boiler room where the breaker panels are, and I noticed that for about half a second, the lights dimmed and then was a moderately loud hum coming from the panels. All of this occurred within half a second. This does happen quite often and I forst noticed it many years ago. Do any of you know what causes this?
my guess is its most likely to be that the boiler is starting up

[QUOTE=No_Excuses;37319042]I've been electrocuted twice and had a capacitor explode in my face. I accidentally reversed the polarity on one when charge testing a bunch of them and it blew its contents all over my face and hand.[/QUOTE] I put a barbecue lighter up to a watch battery and watched it expand and blow up if that counts for anything! Had gunk all over mah face and arms. It was old though. Didn't matter.
[QUOTE=TippZ;37345204]my guess is its most likely to be that the boiler is starting up[/QUOTE] The boiler dosen't start when that happens.
WELLLL, I'd suggest that maybe there's some kind of large draw from something, either from a neighbour (grow op maybe? :v:) or something in your house like a furnace/computer/hairdryer/oven
[QUOTE=VistaPOWA;37318034]The only radiation coming from them is EM and Geiger counters cannot detect that.[/QUOTE] geiger counters can detect gamma and x-ray
Because gamma and xrays are the same thing. It's just that gamma rays come from decaying elements and xrays come from other sources. Anyway, while a meter could produce x-rays, they would have an energy under 240/110 volts and thus would be blocked by only a few cms of air. The x-ray/gamma rays emitted by x-ray machines and radioactive materials is in excess of 30kV, with radioactive materials usually emitting in excess of 1-2MV So yea, that meter thing killing a garden is complete bullshit
Woo FP Electricians unite! I'm from California and on my second year (about to be my third) of apprenticeship. I have a question for the guys in Europe, do all you countries deal with the same voltages? From what I remember the UK runs of 230. In the US we have 120/240V for residential and 120/208V and 277/480V for commercial. I'm just really curious as to what it's like being an electrician in other countries.

I have no idea what the meter would be producing that an analog wouldn't. A radio call to the company, perhaps? Also being afraid of EM radiation is mostly silly. It's like, everywhere. Though there is substantially less in the National Radio Quiet Zone (in the US, though surely there are similar places globally). That's about as low as it will get.
[QUOTE=munky91;37352536]I have no idea what the meter would be producing that an analog wouldn't. A radio call to the company, perhaps?[/QUOTE] They wirelessly communicate with the power company, and they allow the power company to shut one's power off without sending someone out there to do it manually. If you have health or privacy concerns about this you are literally delusional. [editline]22nd August 2012[/editline] Electrical Engineer here, by the way.
I'm a student :D
[QUOTE=Runar;37352511]no no no TippZ no no, we have 230/400 just like you do![/QUOTE] you do? my teacher lied to me then
Wait so do you guys use 230/400 for everything?
yep
I'm building a clock with nixie tubes and it involves electricity
did some work on a fusebox today at small house weve been renovating. shouldve taken a pic of the old one but fuck that starting off, all cables hanging loose... marked them up so i know which one is which [IMG]http://dl.dropbox.com/u/7391317/Random%20bilder/2012-08-22%2010.31.04.jpg[/IMG] set up the main switch and the "Residual-current device"(?) dunno what its called in english but google told me that [IMG]http://dl.dropbox.com/u/7391317/Random%20bilder/2012-08-22%2011.24.59.jpg[/IMG] adding some fuses and starting to connect some cables [IMG]http://dl.dropbox.com/u/7391317/Random%20bilder/2012-08-22%2011.55.43.jpg[/IMG] more fuses! [IMG]http://dl.dropbox.com/u/7391317/Random%20bilder/2012-08-22%2012.46.53.jpg[/IMG] all done! too bad the last fuse somehow got a fault somewhere which makes the "Residual-current device" go off, gonna check up on that tomorrow! [IMG]http://dl.dropbox.com/u/7391317/Random%20bilder/2012-08-22%2014.43.47.jpg[/IMG] the guy who lives there is gonna build some kind of cabinet to cover up the fuse box, so thats why we didnt bother covering the cables and stuff
weird looking breaker box. [editline]22nd August 2012[/editline] wait, breaker boxes are the same as fuse boxes right?
yea i only knew the word fuse box though its hard to remember all the terms in another language
[QUOTE=TippZ;37353374]you do? my teacher lied to me then[/QUOTE] Yes, we do. He lied to you. He betrayed you. You must get your revenge.
hes retired and im not in school anymore so..............
[QUOTE=TippZ;37362525]hes retired and im not in school anymore so..............[/QUOTE] maybe you should go back
why would i go back to school if i got a job and earning money

[QUOTE=Adelle Zhu;37361257]weird looking breaker box. [editline]22nd August 2012[/editline] wait, breaker boxes are the same as fuse boxes right?[/QUOTE] Yeah. It doesn't have the outer metal casing, which is why you're kind of questioning it.

Aren't gamma rays a significantly shorter wavelength and more energized?
