do you guys usually work with the circuits live?

In canada we use 600V phase to phase/ 347v phase to ground in industial/commercial applications and sometimes we are put in a scenario where we have to work live in a junction box.

So my second question is, how often do you guys get shocked?

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?

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.
