For personal safety reasons. In the UK the line voltage is 230 volts and this voltage can be lethal in a wet construction site. The step down transformer used has a centre tapped secondary winding of 55v+ 55v make 110 volts.The centre tap is earthed to the power tool etc, thus making the maximum potential for electric shock at 55 volts:-sub lethal. <><><> Supplies of 110 volts are recommended for use on construction sites for personal safety reasons, on the basis that, if any wiring or equipment casings become "hot" or "live", the danger of electrocution is greatly reduced compared to the certain dangers that would exist if supplies at higher voltages, such as 230 volts ac, were used. In countries running a 50 Hz power supply service, 230 volts ac is the common voltage supplied for use for normal lighting, appliances and small electrical tools and equipment - except on construction sites, where the use of equipment running on 110 volts is now mandatory to meet the requirements of Health & Safety laws.

Can a 2-pole circuit breaker be used for 110V 220V or 440V?
All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.
Can you use 110v 60Hz supply for 110v 50Hz equipment?
If the load is non inductive and straight resistive then there is no problem. Inductive loads like motors, a 60 Hz device can be used on 50 Hz but it is much harder on the equipment if 50 Hz is used on a 60 Hz system.
What is the voltage and frequency used in US and why?
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
What is the Scope of work for Site Electrical Engineer?
Site engineers perform a technical, organisational and supervisory role on construction projects, setting out and determining the location for above and underground infrastructural installations involved in construction operations. Site engineers apply designs and plans to mark out the site and can be involved in projects ranging from small scale to multi-million pound ventures. This may include civil, road, rail and other infrastructure projects. A site engineer works as part of the site management team liaising with and working alongside architects, engineers, construction managers, supervisors, planners, surveyors and subcontractors. They share responsibility for site security, health and safety, and the organisation and supervision of material and human resources.
What is the US calculation of 110V 60hz?
Do you mean definition? If so 110V = 110 volts-60hz = 60 hertz. Hertz is the cycles that the electricity runs at. 60hz. is the US standard. Europe is at 50hz.
110v electrical wire color code for construction site?
black

What type of motor is used in a 110V ac drill?
The motor for a 110v ac drill is a 14 amp motor. The 110v drill is used for household products and construction work. This is a tool that is not limited to wholesale purchases.
What is meant by the term construction site?
Construction site is an area where something is being built. It can be used to describe anything from a building, road or even website that is under construction.

What are some uses for iron metal on a construction site?
Iron is rarely used in in its pure form for construction due to the ease with which it corrodes. However, it is frequently used to make steel which is then widely used on construction sites for things like girders.
