do you guys usually work with the circuits live?
Only when trouble-shooting in emergencies, then the power gets cut anyway, before any real work happens, that requires tools.
In canada we use 600V phase to phase/ 347v phase to ground in industrial/commercial applications and sometimes we are put in a scenario where we have to work live in a junction box.
does it say that you have to
So my second question is, how often do you guys get shocked?
The smart electrician never gets an electric shock.
One other thing, people outside of the trade, always ask me when out on a job "How many shocks have you had??", this really annoys me to bits, it's like the general public seem to think we are a bunch of numb-skulls that fly into a job without any testing or isolation procedures.
I received a s brief shock at 347 the other day working in a live J-box where conduit was installed right under it and I guess i grounded my elbow... it was a surprise more than anything but makes me wonder at what point can i hurt myself?
You want to go and get a lottery ticket, mate, a lot of people have been killed with a "brief shock" of lesser voltage.
BTW, having bare skin showing when working on anything that could be live around a lot of grounded metal, is, to say the least, silly.
I know people that have been dismissed after accident investigations, finding that even though they were wearing gloves, they had bare arms.
Wearing insulated gloves (and outers) sets some people into a false sense of security, they are NOT an excuse to work live, in fact, anyone that has used them to any great degree will tell you they are more of a nuisance than anything else.
I only use mine when I have
to, aside from that, they stay in the truck in their proper container.
We always try to be careful, but mistakes do happen and I just want to see how frequently this happens to you sparkies out there.
There is also an idea called "minimising the risk", this is what the LOTO system is designed for.
One concept I was offered during my apprenticeship, was that "All wires of any type (even ground wires and neutrals) shall be treated as live, until such time as it is confirmed with proven test equipment, that they are not"
I've never forgotten that line.
