That picture seems to have a problem with addition.
'electric doctor photos' needs to take an actual measurement instead of just creating graphics from stray images.
I don't know what math you are using, but the picture is correct.
Plus add a note that the actual voltages can vary.
Very true!
Some areas of the country will have 110/220.
Some will have 115/230. This is what many appliances are rated for.
And, some will have 120/240.
Those voltages may vary anywhere from plus or minus 1 to plus or minus 5 VAC.
However, for those who wish to install a 30 amp RV outlet, be advised that even though the outlet and plug look exactly like old-fashioned 220 VAC equipment, the RV is wired for 115 VAC! That is; L1, Neutral, and Ground.
