What is the difference between a machine with 240 voltage and another with 110 voltage?

Question

in most site,machines with 110 volts are normally accepted.what is the difference between two machines with 110 and 240 volts respectivelly.

Answer 1

The normal supply in the UK is 230v.

Building sites use appliances made for 110v.  This forces workers to use transformers.  These are isolating transformers, which ensure that if you come into contact with a live wire, you are the only ground connection and as such, no current will flow through you to give you a shock.

Answer 2

110 volts on site are there because it is centred tapped, and only offers 55v per live condutor, so the most you would ever get is a 55v shock

if they turn into 230 they will have a Step-up transformer

'old know all' it is the amps that kill, if you remeber 0.4s domestic and 0.2s for site

Answer 3

well not taking the pi$$ here but one in 240 and one is 110 .

the reason sites use 110 in that it is safer

Answer 4

volts are not the problem its the ampage that does the damage,

110 volt equipment is considered safer to use in adverse (wet)conditions,,240 volts is generally used in safer conditions,

also some continental countries use 110v all the time,,in the uk its 240 volts

Answer 5

One just needs more power than the other to function. In the home you have 240 vaults which is excessive for most of our power needs but is needed in most cases by the cooker which draws lots of energy.

Hope this helps explain.

Answer 6

about 130 volts.

Answer 7

More power.  You can only get so much power from a 110 volt motor. Bigger motors need more current which requires more volts.

Answer 8

can kill, won't kill.

Answer 9

the 240 have more voltage then the 110

Answer 10

110 vaults is safer because there is less voltage hence less of a shock!!!

Answer 11

The amount of power a machine uses depends on voltage and current.  A 110volt machine needs more than twice the current of a 240 volt machine.  It's made differently so that the power is the same.  If you tried to run a 240volt machine on 110volts, it would run at about one-fifth speed (if at all).  If you tried to run a 110volt machine on 240volts, it would burn out.

Depending on your build, a voltage of about 80volts is lethal.  The UK domestic mains is single phase, one wire is grounded and the other is at 240volts.  Poke a scaffold pole through that and you're dead.  

Site equipment is split phase so both wires are at 55volts to ground, but out of phase so they're 110volts relative to each other.  Poke a scaffold pole through that and you'd survive.

Answer 12

On construction sites in this country the voltage is 110 volts for lighting and powered tools, the reasons for this are two fold obviously there is less potential in 110 to kill somebody also by going through a transformer you can isolate the the supply from a an earth return which will possibly kill,

How ever there are moves a foot by the gnomes from the HSE to further reduce the voltage to 55 volts

Answer 13

thats easy AC/DC
