[GreenKeys] 2 1/2A SCREW IN FUSE

[Bruce Gentry]

Most ulilities in the USA are extremely reluctant to provide three phase 
to single residences unless the customer is willing to pay thousands in 
installation costs and agree to a signifigent minimum bill regardless of 
the amount used. They will do this even if the three transformers are 
already on the pole in front of your house feeding an apartment building 
across the street. Many people needing or wanting elevators in their 
homes or wanting to restore and install pipe organs have been seriously 
discouraged because of these policies. Many air conditioners, larger 
appliances, and residential elevators today have three phase motors 
powered by inverters that convert single phase to three. Single phase AC 
motors are less efficient- sometimes drastically- than a three phase. 
Their windings are more complex, starting switches and condensors add 
cost size and complexity, and they often will not start under load and 
will be damaged by repeated attempts to start.
