Southwire Extra Heavy Duty Extension Cord, 50Ft, 10 Gauge, 3 Conductor, High Visibility Outdoor Cord, Lighted End, Yellow, 2688SW0002

This extension is beefy and feels solid from the connection points to the materials used. Highly recommend for heavy duty or hard use.

We are using this cord for an portable inflatable hot tub. The resistance on this cord per Southwire provided specs is about 0.5W loss per foot, which is very manageable. There is not noticeable heating on the cord. 10 AWG is properly overkill for the 12A the tub pulls when heating, however, what one has to keep in mind is that heating could accumulate during hot weather, and these small heaters may turn-on for many hours at a time. Also to keep in mind if you consider such installation, to put the joint between the female end of the cord and the plug of the hut tub away from wet areas - you do not want to splash on the coupling between the tub cord and the extension cord and get shocked. And you want to make sure it is protected from accidentally falling into the tub as well. Perhaps elevate and secure it via a stake and some zip-ties. Make sure the entire run of cable is properly grounded. The hot tub has its own GFCI and you also MUST have a GCFI at the outlet where the extension cord plugs in - and use the test button from time-to-time to test whether the GFCI still works. GFCIs are mechanical devices that have a life expectancy and wear out. I picked Southwire because it is a trusted brand. I had bad experiences with HD extension cords where the female end welded to the plug of the load on a golf cart charger application because of too much resistance. This cord is rated for 300V, its jacket is PVC, and it is outdoor rated. PVC is no good for applications where fuel or oil could spill on it, such as in the shop, but a good application for running over the lawn.

Best extension cord I've used so far. I use it to charge my golf cart and EV at 12 + amps

well made

Works well for charging our new electric vehicle. Very heavy; only time will tell whether it will last.

Given this is a 20Amp 10 gauge cord, I expected it to have 5-20R TBlade connectors. It doesn’t, it has standard 5-15 connections.

I've had this cord for several months now and I am very happy with it. I use it with a power inverter/battery back-up set-up I have in my apartment in case of power outages. I can supply electricity anywhere in the apartment without having to move 300# worth of batteries. I chose this heavy duty cord to reduce the voltage drop that occurs as the batteries are depleted. Plus with a heavier gauge wire you get less line loss compared to thinner wires. With cheaper 16 or 14 Ga. cords you can actually lose some of your precious wattage in the form of heat because the wire will heat up slightly when powering high wattage appliances like microwaves, air conditioners or power tools. This loss doesn't occur with a fat 10 Ga. wire.Even though this cord is about 9/16" in diameter it is surprisingly flexible and easy to roll up after use. It doesn't kink or twist either.The lighted outlet is very handy to know if it is live or not. Probably the only thing that would make this better is a triple tap at the end for the same price. (I think that is available as a separate product that costs more.)I know a lot of people will be considering this product for use in construction and the trades for power tools, etc. It will certainly take a lot more abuse in those situations so I can't personally speak to the product's durability under those conditions. It has a fairly thick vinyl outer sheath but I understand there are more durable materials out there, but of course they cost nearly twice as much. But for my uses, and that of the average homeowner, it will probably last for many years.

I use a lot of Drop over the years. Sure wished this was around when I was younger.If you're needing a drop cord. Then STOP looking.This drop cord will be ALL you need. 50' & 30'

Runs my welder no problem it’s built well looks like this will last really good quality and you don’t see that to often anymore. Thanks Southwire

Excelente producto, robusto y de buenos materiales, he tenido bastantes extensiones y esta es de muy buena calidad. Recomendable.

Excellent cord at a great price

I am charging my EV with this while I wait to get my permanent set up. Works great.

Great cord, but very stiff and inflexible. Other than that it is a good cord
