The plugs on this cord seem to be nema 6-50 which are rated for 50 amps. But you only claim 40 amps. Why is that?

Length of extension and ga of wire dictate actuall amps that should be safely carried through wire. This is for a 50A circuit but continuous used should not exceed 40A with a peak of 50A but I am not sure at what % duty cycle. Note, any rated electrical cord is rated @ 100% duty cycle under UL. ie. air conditioner could have a FLA compressive load of 50A an running amps of 15A @ 240VDC and the 40A rating of this cord would be safe in my opinion

I believe it to be rated at 40 amps due to the length of the cable. although I have seen it other places saying its rated for 50 amps go figure.

It is due to the length of the cable and the gauge of the wire in it. Lots of 110 cords with 15A connectors are not rated for 15A.

You probably shouldn't be messing around with electrical if you don't know the difference between a NEMA 6-50 plug with 8/3 wire vs. a 120 plug on your welder, you're going to get yourself hurt.

You can use this surge protector on a 50 or 30 amp. But if all you have is a 30 amp surge protector, it will not work on a 50 amp. Most places we stay we request 50 amp service but if all they have is a 30, this surge protector will work. If all you have is a 30 amp camper, then all you need is a 30 amp surge protector. If you do get this 50 amp surge protector you will have to buy adapters to 30 amps.

I just was checking my 16 FT SMD5050 LED rolls and they run about 1.7 Amps each. For good practice, calculate power supply needs at 2 Amps to allow for some spare capacity. So for 2 cords, that is 4 amps. Since watts are equal 12 volts multiplied by 4 amps. P=VI 48 watts. Probably rated 50 watts. Since this supply is rated 6 Amps, it should be plenty robust.

There is a difference. The cheaper one has to be hard wired to your breaker box. I chose the plug in model because that way, I can take it with me if I go to certain places that have a NEMA 6-50 plug available. Other that that, they are the same. Works just fine though.

No, it has a NEMA 6-50P plug. It looks like a normal three prong grounded plug, but is much bigger. It is Generally used for small welders and such on 50 amp circuits. You probably need a "normal" 15 or 20 amp extension, the thicker the better if it needs to be long -- thee are charts for gauge of wire, length, and amp loads.

That's not a 14-30 plug, it's a 14-20 -- the difference is the 30 is for 30 amps and the 20 is for 20 amps.

As a 50 foot cord it is pretty manageable. It is the medium duty, heavy gauge wire so it can certainly can get in a tussle if you let it. The heavy duty cords are the real bear. If you are running 15 amps or less this is the cord you want. Anything more than 15 amps you need the next size up. Less than 10 amps, you may want to step down and get the more flexible cord at a higher gauge.

Before you consider putting anything in excess of 20 amps through this cord, you should measure the resistance of its wires. Are they really 10 gauge? I measured my cord and got 170 milliohms for the hot/neutral and 270 milliohms for the ground connector along the full 100' length using the three outlet version of this 10/3 cable (http://www.amazon.com/Contractor-Grade-Foot-Extension-Cord/dp/B000BMFWC8), indicating that its fictional 10/3 really means 12/2 for the hot/neutral (with either 19/25 (more likely) or 16/30 (less likely) stranding) and 14 AWG for the ground! The reason I bothered to measure is because it was way too thin and light to be a true 10/3 cable, so I decided to verify, something all of the five star reviewers of this cable haven't bothered to do. Think about it, can a true 10/3 well insulated copper extension cord that is 100 feet long weigh only 18 lbs? Answer: No! There is a reason why this cord has NEMA 5-15 connectors on it and is officially rated 1875 W/15 A - 12 gauge wiring is used for hot/neutral and an appalling 14 gauge for ground.

40 is going to be pushing it with this one.. it seems mostly for standard extension cords. i'd say pass on this one for a 40.

The extension cord I purchased is a 50amp 30' cord. However, this picture seems to show a much shorter cord that the one I have. My cord is heavy and seems like a much bigger coil that what is pictured. Hopefully, this just a misprint for the picture. The price is about what I paid for my 30' cord.

Good evening. You can install one of three different plugs with this unit. It will work with 15, 20, and 30 amp cords. The cord is purchased seperately from the unit. If you have any other questions, feel free to give us a call toll free at 855-770-7195. Happy Holidays from Next Day MRO!

Thanks a lot for your answers folks. I actually contacted the seller and they are sending me a replacement cord! That should fix the whole problem in itself and save us from the hassle of determining the right specification. Appreciate your answers here.

i used it for a heavy duty extension cords and it works perfect. I don't know what size a 40 amp wire is, SORRY

As the other users commented, it's either your stove (not so likely) or your outlet (more likely). If you run low voltage the amps will increase and you'll get a very hot cord. Or, if the outlet is in poor condition your not getting good contact between the plug and the outlet. This also can heat things up. Could be a short in your heater too. But whatever the reason, it should not be that way. My cord has no overheating issues.

Clothes dryer at home usually has NEMA 14-30 Wall socket, whereas this charger comes with NEMA 6-50 Plug.http://en.wikipedia.org/wiki/File:NEMA_simplified_pins.svg

The blades on plugs are arranged various ways for different voltages and amperages. This device NEMA is 5-15 receptacles and cord, which is for 110-120 volts at up to 15 amps. It will not plug into 220v recepts and devices designed for 220v will not plug into it. For a 220v PDU check out the Tripp Lite PDU1230
