TaigaThe "sjtw-a" designation on an electric extension cord indicates the type of insulation material used for the cord. In this case, "sjtw" stands for hard service cord that can withstand higher temperatures and outdoor use (S for service, J for junior service, T for thermoplastic insulation, and W for weather/water resistance), while the "A" typically refers to the cord being approved for use in North America.

Can you plug a refrigerator into a surge protector?
If you mean that the (heavy duty) extension cord has a wire size of #14 or #12 wire in it and that the length is not over 50 feet then you will have no trouble running a refrigerator. Keep in mind that you only use extension cords as a temporary measure and that they are not to be used as replacements for permanent wiring.
Is it safe to cut and splice wire a normal 12v-125 amp 1625 watts max extension cord into a hanging light chandeliere fixture that has just two electrical wires?
It is not recommended to splice an extension cord for use in a permanent light fixture. Extension cords are not designed for this purpose and may not provide a secure or safe connection. It is best to use proper electrical wiring and components for permanent fixtures to ensure safety.
What do the ribs on one side of an extension cord wire mean?
The ribs on one side of an extension cord wire typically indicate the "neutral" wire. The neutral wire is responsible for completing the circuit, allowing the electricity to flow back to the power source. It is important to correctly identify and connect the neutral wire to ensure safe and proper functioning of electrical devices.
What is the amp numbers on a extension cord mean?
There should not be any amp numbers on an extension cord. The only numbers you should see is the insulation rating which might be 75 or 90 degrees C and the conductor count and wire size. It should look like 14/2, 14/3 or 12/2, 12/3. What ever the combination is, the first number is the wire size and the second number is number of conductors in the cord.A # 14 conductor is rated at 15 amps, #12 at 20 amps, #10 at 30 amps. There are light weight extension cords that use #16 size conductors. My advice is to stay away from any cord smaller than #14. Best home owner cord is a #12 at 50 to 100 feet.Larger that #12 is used on construction sites and are usually made to order, for different types of portable equipment, by an electrician using twist lock ends so that they don't accidentally get pulled out.
