This cord/splitter item is critical to make full use of many 120/240V home use generators. Say you have a 5000 Watt 120/240V generator. This means it has two separate 2500 Watt 120V windings. Many generators give you a single 240V outlet and two or three 120V outlets. However, all the 120V outlets are wired to the same winding on the generator. So if you only plug in equipment to the 120V outlets, you really only have a 2500 watt generator. If you load it up with too many connected items, it won't stall... but the single 120V winding in use will eventually melt/fail. Using this L14-30P 4 prong plug with 2 - 120V outlets allows you to use the 240V outlet on your generator and convert it to two 120V oulets, but each one is now connected to a different winding on your generator. You can take power from both windings in your generator and use the unit to its full capacity. Using this cord with a couple of "triple taps" would allow you to plug in 6 household items and spread that load evenly over both windings in your generator.

This splitter has a L14-30P plug that connects to the 240V/30 Amp socket on my PowerMax/DuraMax XP4400E generator. The other end is a Y-adapter that has two NEMA 5-15 or 5-20 120V outlets that can be used to draw 15 Amps (5-15) or 20 Amps (5-20). There is an LED in each of the outlets, so you know when it is live.
As stated my RJB "Engineer at Large" in his excellent review of this product, using the 240V/30A output from the generator is the best way to ensure that both windings on the generator are used equally.
The only thing I want to add to his review is the Y-adapter is built well, has 10-gauge wire at the L14-30P end (necessary/required for 30A), but has 12-gauge wire at the 5-15/20 end, which is sufficient for 20A.
