What is a L14-30R plug?

Product Description One L14-30P male plug and one L14-30R female connector, used for making a generator power cable. Rated for 30A, 125/250V, the male L14-30P plugs into a generator receptacle, and the female L14-30R plugs into a male plug or inlet box. Rated for 7500W Generators.

What is a NEMA 14 30 plug?

The NEMA L14-30 twist lock receptacle is the type you usually find on portable generators that provide 240-volt electricity. The plug is rated by the National Electrical Manufacturer Association to supply 240-volt electricity at a maximum current of 30 amps.

How do you tell which wire is positive and which is negative?

If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
