The guy on final test stood on a rubber block but still used to get blown across the floor once a month
Sure I expect my line voltages to vary especially given that the actual spec for my line voltage (UK) is 230V +10%/-6% – my nominal voltage where I’m sitting is around 242V and I’ve seen it go as high as 252 and as low as 220.
Don’t blame the Chinese for this one! They are more than happy to sell us any quality we want. For example, you are probably reading this on a very well built, Chinese made, smart phone.

There are split-phase premises supplies and three-phase. Split-phase is used for residences and small businesses, and three phase is used for larger businesses and some larger multi-tenant buildings. When using two of three phases, they’re 120 degrees apart and the nominal voltage is 208 volts. When using both sides of split-phase, the two are 180 degrees apart and the nominal voltage is 240 volts. The nominal voltage from one phase to neutral is 120 volts.
The run and start capacitors provide the phase shift for starting torque because their capacitances add up when wired in parallel. In fact, both capacitors are wired in series with the start winding and in parallel with the run winding.
