Extension Cords Amp Rating, Amps, Amperage Chart
1XTech Fig. 1. Refer to Sec. 400.5(A) and (B) for guidance on the ampacity of flexible cords.
We can see the various types of flexible cords and cables in Table 400.4, which takes up seven pages and comprises more than half of Art. 400. The first rule of working with flexible cords and cables is to always use that particular table when determining the extension cord amp rating.
Some other basic NEC Extension Cord rules to always keep in mind include:
- Always use a cord and fittings identified for the application [400.3].
- Never use a flexible cord or cable in place of a permanent wiring method.
- Replace instead of patch or repair a damaged cord or cable. Don’t chance it!
NEC 400.5 Extension Cord Ampacity Rating
NEC PDF ART 400.5 Click to Download PDF
NFPA NEC Tables 400.5(A) and 400.5(B) list the allowable ampacity for flexible cords and flexible cables with not more than three current-carrying conductors at an ambient temperature of 86°F. The tables assume copper conductors.
The ampacity from Table 400.5(A) or Table 400.5(B) may need to be adjusted as follows:
- If the number of current-carrying conductors in a cable or raceway exceeds three, adjust the allowable ampacity of each conductor with the multipliers listed in Table 400.5.
- If the ambient temperature exceeds 86°F, the temperature correction factors listed in Table 310.16 are used to adjust the flexible cord or cable ampacity

Extension Cord Question and Answer Q&A
This section of the 1X Technologies extension cord educational resource will answer many of the questions we receive on extension cords each day. We will continually update and refresh this list of questions and answers to help serve you better.
If you find that your question is not listed feel free to contact us to get the question and answer added.
We would love to help you.
Are Extension Cords Safe?
Question: Are Extension Cords Safe?
Answer: Yes, extension cords are safe. but it depends on you following good OSHA and NEC safety protocols and using the extension cords properly!
Extension Cords Safety YouTube Video (1 minute 16 seconds) – Click to watch
Are Extension Cords Waterproof?
Question: Are Extension Cords Waterproof?
Answer: If your portable cord that is used to make your extension cable ends with the prefix W than YES it is water-resistant or waterproof!
Additionally, if we manufacture a custom extension cable for you we can ensure that the cable style we make is rated for submersion in water.
In the United States, letter codes have been defined by Underwriters Labs (UL) to describe various attributes and ratings of portable cords. The Canadian Standards Association (CSA) also has defined similar letter codes, and ongoing standards harmonization should eventually resolve minor differences.
S = Severe Service Cord – 600 volts (also 277/480 or 480) – Cord May be utilized in place of SJ or SV in extra-severe service
SJ = Junior Severe Service – 300 volts (also 120 or 120/208 or 120/240 or 240 or 277, but not 277/480)
SVT = Vacuum cleaner cord, or light-duty cord
T = Tinsel Cord (only if the first letter of code for a portable cord)
T = Thermoplastic (if not the first letter of code)
H = Heat Resistant
HH = High Heat Resistant
N = Nylon Outer Jacket Material
E = Elastomer (flexible thermoplastic that looks and feels like rubber)
O = Oil-Resistant Outer Jacket
OO = Oil-Resistant Outer Jacket and Oil-Resistant Interior Insulation
P = Parallel Cord (conductors are not twisted around each other)
V = Vacuum Cord – 300 volts (typically used with vacuum cleaners and other portable cleaning equipment)
W-A = Weather Resistant (UL approved for indoor and outdoor use)
W = Weather and Water Resistant (CSA approved for indoor and outdoor use)
Are Extension Cords Grounded?
Question: Are Exstension Cords Grounded?
Answer: Yes! Most Extension Cords have a ground wire and a ground Pin on the connector.
This image shows you what a ground pin looks like on your extension cord. Most of us have seen this even on our trusty green Christmas extension cords.
How do I Store Extension Cords?
Question: How do I Store Extension Cords?

Are Extension Cords Color Coded? (Do Extension Cord Colors Mean Anything?)
Question: Are Extension Cords Color Coded? (Do Extension Cord Colors Mean Anything?)
Answer: Yes! When it comes to the electrical color code of an extension cord you will refer to the electrical Industry standard on “Color Code for SO Cords (Portable Power Cable Colors)”. Extension cord colors do mean something, it has to do with the industry-standard color code. Additionally, if you have a custom application that you need special colors on you are in luck. 1X Technologies will manufacture your custom colored extension cords letting you choose the exact color you want using the Pantone custom color wheel.
Are Extension Cords AC or DC?
Question: Are Extension Cords AC or DC?
Answer: Both! Electrical Extension Cords and most other cables are manufactured as conductors of electricity, whether that is an AC or a DC system, does not matter. So you’re saying extension cords are AC/DC? Yes, but don’t get Thunderstruck!
Can Extension Cords be Buried?
Question: can extension cords be buried?
Answer: Typically NO. We say typically because we do manufacture large-sized extension power cables that are dual rated as Direct Burial TC-ER. These would be sizes 1/0 and larger and would be used mostly in the heavy industrial applications, mining, etc.
Typical Extension cords are made from SOOW, SJOOW, and other portable flexible cord types which are designated under NEC Article 400. They are NOT rated for direct burial or for permanent installation.
If you require an extension cord that is direct burial rated just let us know, we can make you exactly what you need.
How Extension Cords are Made?
Question: How Extension Cords are made?
Answer: We have supplied you with an epic youtube video showing you how extension cords are made from start to finish above. If a picture is worth 1000 words, this video is worth a billion. Have at it!
