Use your whole generator
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.
Is it unfair that you have to buy this somewhat (~$25) expensive (but very sturdy) “cord” to fully utilize your generator that you paid so much for in the first place ? Maybe so….but at least it solves the problem easily! You can check your generator’s owner manual to see if all the 120V outlets are attached to only one winding. Some more expensive units may have 120V outlets on both windings. However, I have a fairly expensive Yamaha 6600, and all my 120V outlets are on one winding / one breaker. I had built a homemade cord to perform the same function, but this item looks more professional and is more sturdy. Spread the word to your friends and neighbors who may have bought themselves a nice generator, but may not be utilizing it to the fullest extent, or are facing damage by overworking just one of the windings.
Perfect for 30 amp 120V/240V generators
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.
EASIER TO USE THAN 25 FT
PURCHASED THIS 3FT Y ADAPTER L 1430 TO USE INSTEAD OF THE 25FT THAT I’D BEEN USING.NO NEED TO WIND THIS ONE UP AND IT USES A LOT LESS SPACE TO STORE.HAPPY WITH THE 3FT ADAPTER.
High Quality Power Splitter
This Y adapter splits your generator’s full power 240 VAC to 2 – 115 VAC outputs. The price is amazingly LOW for such a HIGH quality product. Be aware this has a 30 amp twist lock plug and will NOT fit a 20 amp twist lock jack. Check your generator. If it has a 30 amp twist lock jack this is a must buy.
Increases the output of a generator
I was sold on this adapter after reading about what I’d suspected, that the 220V side of most generators are separate windings from the 110V side. So, unless you have a need for a 220V power supply, the generator is being under-utilized, and the windings that comprise the 110V source are being used solely. I gave this adapter a try-out on my little 4500 watt system, hooked two space heaters to it and ran them at low, then high settings. The generator definitely pulled down and was struggling with both on high, but it did the job. The cable warmed up a bit, but worked flawlessly. So now I have more outlets available if the power goes down again like it did here in SoCal last year for about 12 hours.
generator 240 side twist plug
This is a great buy and solves the power problem. this splits the 240 1ph to two 110v stnd house plug ins. Now I can run two 18 amp grinders off the generator and not blow the breaker. it takes 110v from each side of the windings on the genset.
Results in more power!! arh arh arh! This is the only cord you need for portable power. Great price too
This adapter is solidly built and fits perfectly in the DuroMax Elite MX4500 generator’s (also purchased thru Amazon) 4-prong 250V female socket. Allows use of the generator’s two 125V windings to take full potential of the generator’s max output. Adapter is a little stiff when first used due to the heavy gauge wire construction. Lighted 15/20 Amp female connectors (when current flows) are a nice touch. Would purchase again.
Due to flooding and power outages this year I decided to invest in a portable generator. I need to run two sump pumps during heavy downpours. This splitter allows me to do that. Yes, it works.
Great adapter cord.
These Y-adapter cords can be very expensive and very difficult to fabricate yourself. This one was about $18.00 and too good to not get. It is built very solidly and worked great.
Super heavy duty!
This cord adapter is built like a tank. I was really surprised when it arrived. and I thought they had sent the wrong item until I inspected it. The photos don’t do it justice…it is almost ridiculous how dense and heavily made this item is. It could double as a medieval mace! I must say I’m not used to getting more than I bargained for!!
