Let's be honest here. I am curious as to how many of us work with live power? As in making live connections, working inside panels and switchgear, removing receptacles etc. Is there a threshold? Only up to 120V? 347? higher?
On residential work, I'm pretty bad about working hot. If there's a switch near by, I'll turn it off, but I'll replace that same switch while hot. I'm very carefull, rarely get shocked, and my tools don't have burn marks on them. However, while I don't require it, I do encourage my guys to turn off the juice.

Sometimes you have to work it hot when troubleshooting. I work hot up to 120 Volts. Anyhting hire power has turn off. I remember reading somewhere that majority of electricians get electrocuted by 120 volts vs higher voltages.
When you turn the power off that does not mean that it is off. You have to check it twice. I got shocked last week when i took wires off of three brakers in a panel. Apparantley there is a backfeed.
I hate it when that happens.

I allways work it dead. I have the Amprobe Pasar meter. It has a great record so far in telling me what ckt. breaker operates the device I need to kill. Cost a few bucks, but it's real good. Also, if any one is working on a computer at the time, I would ask them to log off temporarily, just in case I knock that off too. Better to work it dead when ever possible. You only go around once.

The standard is to work in dead circuit for safety.But sometimes we need to work on live circuit but an extra precaution must be made.If only in resedential wiring it is safe to work on circuit which is dead.But in some cases where I worked wherein power is essential and not to be interupted I become more safety minded, I see to it that I have a long sleve/cover all, safety shoes, gloves in short I isolate myself to earth by puting extra essential clothing.But I limit the voltage to 240V otherwise it is very dangerous working with higher voltage unless you are wearing proper protective devices.
DON'T MEDDLE WITH ELECTRICITY... THINK SAFETY FIRST...
