I can't find 16 gauge heavy duty extension cord!
 
I recently purchased a 1/3 hp drain cleaning machine, and the manual says it needs a 16 gauge heavy duty extension cord. But at the hardware store all the 16 gauge extension cords are labled 'light duty' and only the 14 gauge extension cords are labled 'heavy duty'.

So should I just get a 14 gauge extension cord, or keep looking for a 'heavy duty' 16 gauge extension cord? I want to stick with exactly what the manual wants. Also could there be problems with a 14 gauge cord, could it 'overdraw' on power and pop a circuit breaker?

I'd buy the 14g cord myself
You can't overdraw power
The motor will only pull as much as it is rated for

The gauge provides the current handling capability - a physically larger gauge than specificed is ok, and a good thing especially in longer extension cords.

The "duty" typically speaks to the ruggedness of the extension cord in relation to abrasion and cutting, connector robustness, etc.

I like the Bosch XC series extension cords - rugged, stay flexable at low temperatures, and have a light in the end to make it easy to know you have power on the cord.

. . .of some maximum length

Just curious: what is the rated amp draw and what is the max. length #16 cord you're allowed?

What seems to be constant with the cord-size/length tables is a ~5% voltage drop@rated current, but that doesn't always work.
That link to the 100' 16 ga. 10A gives a 7% voltage drop at 10A@120v if it's copper, worse if it's aluminum.

Heh, did it also say that you should go hunt snipes? 14 or even 12 is fine. The bigger the wire the longer cord you can use.

Ah the good ole days of snipe hunting!!!:thumbup:

Farm Supply stores have the heavier gauge cords.

I got a 100 foot 12 gauge cord at Harbor Frieght for 38 bucks last year. It's heavy, but I use it to run lighter gauge cords when I am a long way from an outlet. Go with 14. It's a good compromise: not so heavy and plenty of capacity for high amp tools.

Owner's manual causing confusion

The term "16 gauge Heavy Duty" is self contradictory. #16 AWG. wire can not be applied for heavy duty use. You don't have to be concerned when using #14 wire. Maybe you're not aware (as are many people not familiar with Electrical terms and standards) that AWG, which stands for American Wire Gauge, works somehow in reverse. (There's a logical explanation for that, too). The higher the #, the thinner the wire. The largest sizes of wire (past Zero) are measured in Number of Zeroes, or in MCM. (Which stands for Milli Circular Mills). (No matter what) :yes::no::drink:Don't Drink and Drive!!!

The first "M" in MCM is actually the Roman numeral for 1000. That's why it has been replaced by kcmil (kilo-circular mil). Who the hell uses Roman numerals? (except at the end of movies!)

Thanx. When I went to school they were still using Horse and Buggies to get around. Just kidding! (No matter what) :laughing::no::drink:Don't Drink and Drive!!!

I hear you on how heavy a 100' #12 ext cord can be. My wife was at Lowes and called me about a sale. I told her to get the 100' #12 for $40.00. I never ever remembered using a cord this heavy. But for the price it was a good deal. Got to get some sun on it so I can roll it up properly.

Haha, try lugging around a 100' 6/3 extension cord! Now that is heavy! I think I have probably 5 100' 6/3, a 75' 6/3 and a 50' 6/3. I use them with portable sub panels; they rarely get used but I had a wedding I ran sound and lights for once and used almost everything I had. I am wiring up some outlets near my service panel to make use of them at my house for when I need that extra temporary power.

Scuba_Dave 08-04-2009 01:44 PM

Yeah I bought (2) #12 100' cords when they were marked down to $38

I used them in my Christmas display plus a couple hundred moire cords :eek:
Also used them as Temp power to my shed to keep the pool running while I ran a new sub
