For non-industrial sitting on the power pole
H1 and H2 transformer line voltage input
L1, L2, L0, output to the service drop.
L0, of course, is neutral
SPLIT PHASE motors do not need start or run capacitors. Their startup draw can be 5 to 8 times that of run current. Just the thing to not connect to a new digital demand meter. Split phase motors are 120vac like vacuum cleaners.
Wanna have fun? Take your meter aboard a trawler and start searching for low voltage leaks. Or ground interfaces between dock power and generators. Exposes self-declared EE's in mere seconds. Zincs and propellers are not inexpensive. Another way to expose a fraudulent "EE" is to turn him loose on a bank of transformers trying to resolve an earth ground eddy loop.
Analyze a 50 amp 240 service
L1 to LO volts
L2 to LO volts
L1 to L2 confirmation
L pick one to earth ground
L0 to earth ground
Most campgrounds have 3-phase and 99% of the time you will discover by moving around and checking the weak sister phase lowest voltage of the three phases. The problem is when you suck down 2 of the 3 phases the third tends to rise.
Carlos had me wire up a Scott connection for the heaviest loaded spaces in his Mazatlan Park.
