Great cord for my generator
Very substantial cord for use with my generator. I just wish Southwire or someone would make a "FLAT" version of this. That way I could run it under my closed garage door.

Works well
I keep it coiled up on my generator when it's needed. Used it twice and it runs the well pump, fridge, and freezer just fine.

Electrical cord for use with generator
This cord is very well made and easily fits into the appropriate 30-amp Reliance Controls Generator receptacle. Keep in mind you are required to push in and twist to get the proper seating in the outlet. I am pleased with the purchase other than the cost for a twenty-foot extension cord seems a bit high (as do most things these days). Would recommend to others.

Fantastic Value and Very Heavy Duty
I looked at 'more buying options' and found a used one (10') for $17 fulfilled by Amazon. I'm not sure what made it 'used' but it came in the original box with all the labels attached. I'm sure it would have passed for new. I only needed about 2' of this cord to make a short run. I also needed to put a L5-30P plug on the male end. I cut off about 8' and put the L5-30P on the short cord. It's being used to bring 30 amps into my house from a 4500W generator. Works Great! For $20 I was able to custom make what I needed with 8' of wire left over. If you found this review helpful, please let me know. Thanks.

Great Generator Cord
Pretty simple. There are more expensive cords and less expensive cords. Southwire is an established company with a good reputation. I chose it on that basis. Face it, you likely will not use this cord all that much if you have a reliable power utility, so do no over-spend for something you may only use a couple times in your lifetime!
