FAQ:

Q: What is a 3 prong power cord?

A: In a properly-wired building, neutral should be at ground potential and will not shock you. On a 3-prong power cord, you still have hot and neutral for carrying power. But there’s also “ground” — a wire that is connected to the earth for the sole purpose of draining unwanted power for safety & electrical shielding.

Q: Can I plug my RV into my dryer outlet?

A: Recent Listings. If you know what you are doing you could use the dryer outlet to power your RV. You could use just 1 phase+neutral+ground from the existing dryer recepticle. You would need a male plug for the dryer outlet and wire it for just the 1 phase. One leg of the dryer plug, for the other phase, would not be wired at all.

Q: What is a power plug adapter?

A: A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage . Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits.
