What is the difference between a plug and a receptacle?
A plug has prongs or connecting pins that fit into a receptacle (also known as a jack). A receptacle usually has a flange with holes so that it can be mounted to a surface. Bottom line: Every connector plug has a mating plug receptacle — and vice versa.
Why is one side of a plug larger than the other?
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 do the NEMA numbers mean?
NEMA designations are based on a two part code where the numbers before the dash represent voltage and wires and the numbers after the dash represent amperage. For example, the “5” in the common NEMA 5 15 represents 3-Wire 125V and the “15” represents 15 amp.
What is the difference between NEMA and non NEMA?
The main diffrerences between NEMA and non-NEMA configurations are the blades and grounding stem on the plug and the connecting blades. Grounding blade is formed using the same thickness of material as the other blades for a solid, rigid connection.
Why are there 2 holes at the end of electrical plugs?
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.
Does it matter which side of outlet is black wire?
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. 3) Strip wires, about an inch.
What are NEMA outlets used for?
NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association.
How many 15 amp receptacles can be on a 20 amp circuit?
In most residential areas, you can find a 15-amp and a 20-amp receptacle. The 15-amp outlet is good for the average household accessories such as lamps and chargers, while the 20-amp outlet is best for heavy-duty appliances like power tools in your garage. These two outlets can both connect to a 20-amp circuit.
Is it OK to use 12-gauge wire on a 15 amp circuit?
Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
