Why is 110v used on site

I'm not sure the same rules apply to kitchen fitters though because most of the ones I meet use v tools!! There are a couple of factors that will affect which transformer is best for you. I've always bought v power tools because even though I have to carry around a heavy transformer I know I'm not going to get turned away from a job by the site agent for health and safety reasons.

I use a twin socket transformer which is plenty powerful enough for the carpentry v power tools I use. If you are only going to use the transformer yourself for things like a mitre saw, Hammer-Drill, planer, jigsaw and other normal v power tools then this 3KVA V Transformer like mine will be more than sufficient for you too.

Been in Norfolk, now back in Ethics. Your body's inherent resistance doesn't know what the voltage is. So if you stick your hand across v, X milliamps will flow. It's very risky, unless you're like me, with unusually dry skin and hence very high skin resistance.

Then you swear very loudly. I've probably done it four or five times in my lifetime and have now given up the idea. Personally, if I were in a situation where I might grab hold of the electric supply, I'd rather it were something like 24 volts.

Even can be a nasty surprise if you grab one pole with each hand. I've had hold of something that was at something like , volts - but there was no power available, and virtually zero milliamps. It was amusing to see the inch-long spark leap to my finger, and it tickled a bit. Do that with the overhead national grid at the same voltage, and you'll be smoke.

At V this gives a current of 2. Does that help? By BlueRobin - Sat Jun 09, BlueRobin wrote: My shed is full of v power tools, apparently it is to do with site safety. My shed is full of volt power tools. It's to do with living in England rather than the USA. You get far better performance at the end of a long line with volts rather than volts, because you need less than half the current to provide the same power.

That's not an issue with small stuff, but most big stuff in the USA has to be 3-phase because they can't pull enough current through practical sized cables at volts. The threshold in Europe where 3-phase becomes essential is a long way further up the scale.

Whether it's advisable from a fashion point of view is a different matter, though. What is V? Do you Need V? Like this story? Please Share! Like our site?
