The top hole of an older three-prong 240-volt plugs looks like a backward ‘L’and the other two holes are diagonally placed on the sides..
What happens if you switch hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. … One of these wires is connected to the earth, or ‘grounded’, so this wire is called the grounded conductor.
Can I run a 30 amp dryer on a 50 amp breaker?
As long as the dryer cord itself is rated for 30 amps, be it in 3 or 4 prong form and making sure the breaker/wire is the same. If the wires coming out of the panel/junction box is 4 wires, it needs to be 30 amps for an ELECTRIC dryer. Same as if it was 3 wires.
What happens if you hook a dryer cord up backwards?
Also, what happens if you hook a dryer cord up backwards? 2 Answers.

Are dryer and range cords the same?
Though both use a 220/240-volt circuit, a range/stove and a dryer cord are very different from each other and should never be interchanged. … Electric range cords are rated at 50 Amps and dryer cords are rated at 30 Amps. So using a dryer cord for an electric range/stove is not a good thing.

Are dryer plugs interchangeable?
If your dryer has a pre-attached white wire, both wires will be connected the neutral terminal. … The hot terminals are interchangeable; each can connect to the black or the red wire, but only one wire goes on each terminal. Connect the red cord wire to the other hot terminal.
