[GreenKeys] 2 1/2A SCREW IN FUSE

[Ralph Mowery]

The standard US 120/240 volt system has been called many things by people
that 
Don't know the system.

At the power pole for most homes is a transformer that has a 240 volt 
Center tapped winding feeding the house.  It is often called a 
Split phase or center  tapped single phase.

Some try to call it a 2 phase system, but that is not true.
There is a real 2 phase system, but the phases are out by 90 deg.
And would not be common in most homes.

Not sure if it is still used but there is that 3 phase mess
That is 120 volts and 208 volts.  Just not common in the 
Area I live in.
