This single-phase three-pole 4-prong 120/240V 20A locking socket is found in some low-power (typically under 4,000W) portable generators.Its pinout is similar to that of L14-30 except the notch in the ground hole is reversed. If you follow UL and NEC 2014 80% loading guidelines, you can draw from this outlet up to 240x20x0.8= 3,840 VA. The mating plug L14-30P is normally wired with #12 AWG. As usual, red and black leads go to X and Y, white to the neutral, and green to ground (refer to this diagram for the configurations of the terminals).
Does this make sense to anyone? It's an L14-20.
I honestly did not notice that line. Been watching Sky Sports and the game at Soldier Field so distracted a bit..today was not a good day for my fantasy teams lol...
To me it is (incorrectly) showing that there is 208 or 240 volts between red and white.

What if you had run something other then red or black, or even two reds or two blacks?:huh:Yeah it is the voltages that were making me scratch my head. This was a factory installed male. I had to put in a receptacle. I was a little paranoid at first that this was perhaps from China and they were being the (unconventional) decider on which pin is which. After some cogitating, I realized to get those voltages between those conductors, you would need two phases of a 120/208 system (white and red) and a neutral (black). Figured that was a stretch even for the Chicons I wired the recep normally, held my breath and plugged it in and it worked!

Maybe with 3-phase but not single-phase. Can't imagine they are using the high leg for single phase loads.Perhaps the 208 - 230 is not poor signage, perhaps it indicates that if you were to use a high leg, to put it on the Y terminals and, that the X leg to neutral supplies the 120 volt loads.

If that were the case, it would read only 208, not 208 - 230.Perhaps the 208 - 230 is not poor signage, perhaps it indicates that if you were to use a high leg, to put it on the Y terminals and, that the X leg to neutral supplies the 120 volt loads.
