120/220, i am still confused

its just basically so you dont get killed. id rather have someone ground out with the same hand than let the current pass thru the whole body.
i personally dont really work like that anymore, but some of the younger, inexperienced guys should.

Just a question bro I'd say 90% of my experience working hot circuitry was tapping into 277V lighting circuits in existing office bldgs,the ladies and lawyers can become quite frightened if you kill their lighting circuit for a half a fuckin second lol,so you do it hot.If your right handed,you use your left hand to hold the new wire to the hot wire and your right hand to twist clockwise,unless you have three hands how do you pocket one lol?Theres a lot of commercial/industrial work I've never even seen much less contemplated though,I'm sure the one hand thing applies to a lot of these.Working large feeder wires in a trough "luggin and buggin" might be one of those one handed situations,that would make sense.Tapping into a energized branch circuit one handed would be Houdini like lol.

I've worked on tri-phased circuit and I don't see how you can use only 1 hand. You need to be in control, not handicap yourself. Wear gloves instead, you lose dexterity but not as much as having only 1 hand!!

If you work on high voltage you need boots that have good electric isolation, that way you eliminate a path for the current to flow through your heart, if working standing up.

Single phase-one hand.three phase-three hands!Seriously,I dont know how a person can do it.Even thinking about my "bugging" situation yesterday,it takes one hand to secure the hot wire in the bug,the other to tighten with allen wrench.If this is some kind of common practice these days in certain areas or something,it wouldn't surprise me if insurance companies have a hand in it.One too many apprentices let the smoke out of himself maybe lol.Really though I'd be laughed right off the site if I were caught trying to work something hot with one hand,or sent to a loony bin.On the other hand if Thorodee says its a practice,then its a practice.How good a practice it is is definately open to debate.I need an example of when one handed splicing is preferable or even possible!

obviously you cant splice wires with only one hand.
i should have reworded what i said originally.
1 hand when working in panels/ switchgear. if applicable.
for instance, if you are adding or removing breakers of the bolt on variety.
or tapping off a set of lugs in the enclosure as well.
not everybody has fully insulated screwdrivers or nut drivers. (handles are insulated, just not all the way up the shaft to the tip of the driver)
so if the driver is on the bus screw, you dont want an extra hand there to help you get wrapped.

Thats what I'm talkin about!I can see that just never heard of it or considered it.Always too busy trying to not get ceiling grid fried lol.That would be a good name for a punk band,"one Handed splice".

ok, you can't change the bulb with one hand. i see that you don't understand what thorodee and i were talking about, so i won't try to explain. just use both hands if possible. even if just screwing a wire with screwdriver - use both hand to hold the screwdriver, so that it doesn't slipp away.
