Why are some plugs different?

Why are some plugs different?

Why One Prong Is Bigger. Polarized nongrounding-type plugs have one prong, the neutral, that’s larger than the other to ensure that the hot wire, which is the smaller one, is tapped correctly. Electricity streams in a circuit, which is a closed path of components where electrons flow from a current source.

What are the three Colours of wire in a plug?

Plug wiring colours

Wire	Colour
Live	Brown
Neutral	Blue
Earth	Yellow and Green

Does it matter how you wire a plug?

So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the “hot” half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked.

How do I choose a wall outlet?

How to Choose the Right Electrical Outlet for Your Home

1. Step 1: Know if you need GFCI and AFCI outlets. Most electrical outlets in your home should have some sort of built-in safety device.
2. Step 2: Get the right outlet for your appliances and electronics.
3. Step 3: Know your existing wiring/circuits.

Why do plugs have 2 holes in them?

These bumps fit into the holes so that the outlet can grip the plug’s prongs more firmly. This detenting prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet.

What do the colours mean on a plug?

This can be remembered using the following mnemonics: Brown is live and you’ll be burnt brown if you touch it. Blue is the colour of water and the pH of water is neutral. Green grass grows on the earth.

Does it matter which wire goes to which side of the plug?

White (neutral) goes on the side allocated for the larger prong. Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green.

Can a plug be wired backwards?

In a correctly wired outlet, electricity will flow to the switch; with reversed polarity, it will be present in the item itself even when it is not turned on. In either case, the item will not function until the switch is flipped to close the circuit.

Why do wires have different colors?

But looking deeper, the color of the wires inside of the sheathing reveals that different colored wires serve different purposes. The National Electrical Code (NEC) says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires.

Which prong is neutral?

left slot
The left slot is called “neutral,” the right slot is called “hot” and the hole below them is called “ground.” The prongs on a plug fit into these slots in the outlet. If you have read How Batteries Work, you know that electricity must flow in a circuit.

Should outlets match walls?

Architectural Digest suggests painting outlet covers the same color and finish as the trim in a room for a subtle, textural effect. Keep in mind that if you choose not to paint the covers, the outlet itself and the cover should be the same color.

How many outlets should be in a bedroom?

According to US regulations, no single point measured along the floor line of the room walls should be more than 6 ft away from an electrical outlet. This means that a standard, 12 x 14 ft room needs at least 4 to 6 electrical outlets, depending on the wall space.

Why do British bathrooms have no plug sockets?

Why are there no plug sockets in British bathrooms? The reason that there are no plus sockets in bathrooms is simple – having an exposed plug socket can increase the risk of electric shock. Plugs in England generally use 240-volt power, twice the amount found in US plugs which have 120-volts.

What is the difference between Brown and blue plugs?

Brown plugs fit into 7.0 mm holes and work best with screw sizes 8 through 12, but can be used for screw sizes 8 through 14. Blue plugs fit into 10.0 mm holes and work best with screw size 14, but can be used for screw sizes 14 through 18. Note that not every brand follows the same color guidelines.

Are there different sizes of wall plugs?
