4-prong receptacle, locking receptacle

[iren121]

The voltage selector switches the main power carrying windings of the generator to produce "120V ONLY" or "120/240V". If a 240V appliance is connected to the 4-prong receptacle, the switch must be in the "120/240V" position. If a 120V appliance ONLY is being connected to any of the 120V 3-prong receptacles, select the "120V ONLY" position. The benefit of this is to get maximum power from the 120V 30A locking receptacle.

Еще, как это beyond the circuit breakers?
In the "120V ONLY" position, the power of the two main windings are connected in parallel (beyond the circuit breakers) and full power can be obtained from the 30A 120V receptacle. It is important that the power connected to the different receptacles be applied equally to avoid overloading any one main winding.

здесь это 4-контактный разъем/розетка, запираемый разъем
beyond the circuit breakers - после автоматических выключателей

Cпасибо, вы как всегда меня выручаете. А locking plug это тоже что и locking receptacle получается?
