The disorder results from overproduction of collagen, a naturally occurring protein found in the skin. It is unknown what causes this overproduction of collagen to occur but the immune system is believed to play a significant role. Morphea is not contagious or passed down in families.
A typical US household voltage is 120/240 V, 60 hz, single phase. There is a tolerance and the actual measured voltage is rarely exactly 120 volts. A common reading at my house is 117 volts. Industrial motors are made and rated in multiples of 115V (115, 230, 460, and 550Vac) for use on line voltages in multiples of 120 V (120, 240, 480, and 600 Vac).
The average voltage being used in our homes to day is around 120-130 volts but all of the out lets are the same and all modern electric house hold items run fine on anything between 110 volts to 135 volts.But be sure the spa isn't a 220 volt. If it heats the water it most likely is 220V.est Answer: There is no difference in the two. Originally the voltage in the home voltage was 110 volts. As the power company's learned they could stay with in government safety guide lines and run up to 130 volts and use a smaller thickness wire in the power lines leading to our homes.
