might be good for powering 3 small under 10A heaters in the house when the power goes out in the winter should work good with the champion gen we have.

I believe this would work well for helping me use my table saw in the drive way (because of higher wattage), would anyone have a thought/advice to share?

Double check the plugs this has via the pics b/c they may NOT FIT the receptacle you are thinking of using. That said, both plugs AND outlets/receptacles can be changed relatively inexpensively with limited to moderate DIY skills. Adapters can also be made, so options do exist if it's not a straight plug & play solution for your set-up.

How long are the individual cords? Is it one 20 foot cord and three 5 foot pigtails? Or is it one 5 foot cord and three 20 foot pigtails?

you got me curious too. looks like the pigtails could only be 2-3 feet, but pictures can be deceiving.

edit: PRICE DROP TO $31.30 June 8 , 9 AM PDT


Uses:
Some generators which have the smaller round L5-30r 120 volt 30 amp twist lock outlet.

Most light duty 120 V generators have the TT travel trailer flat blade 30 amp outlet which is annoying. Vibration causes TT plugs to come loose on generators. As the plug becomes loose the resulting surges can damage the generator or connected equipment. If you have this problem you may be able to replace the TT receptacle on your generator with a L5-30 receptacle.

OR, for you generator with a TT outlet:
Cut off the L5-30P and replace with this 30 amp TT plug, This one is of good quality and easy to wire with built-in strain relief: https://www.amazon.com/gp/product/B013GGAD24/

Leave 6" of wire on the cut off L5 plug for re-use.

yup, i just went and checked my champion gen and it has the 3-blade twist/lock 120 and the RV flat-blade in addition to the standard 20a 120 outlet.

champion 4-blade twist/lock cables going back. 2 sets of adapters would run about $30 or about $7.50 an adapter. then there is always the chance of overheat and fire at adapters. grrrr.

Your generator is a 3-4K watt 120 volt? Great that it has the L5-30 120 V receptacle. This 10 gauge cord is made for your application. Return the L14-30 120/230 volt cord and the adapters.

For generators which only have the 30 amp 120V TT receptacle it is worth changing that out for a L5-30 so this cord can be used. Much better than using a bunch of adapters or running multiple cords to the duplex outlets.

yup, just checked return window and right under the 30 days!

im still learning all about generators and right now i have no plans to wire in a transfer switch and buy a huge generator. id rather have 2 or even 3 smaller generators.

neighbors would absolutely love me with 3 fired up around the house and probably show up with their own extension cords in hand! laugh out loud
