Is a grounding 120 volt receptacle larger than an ordinary receptacle?

No, it just has an additional conductor to separate the neutral from the ground, and has a third prong in the receptacle to receive the appliance grounding conductor through the cordset.

The minimum acceptable tension force of the grounding contact in a receptacle is?
The retention force of the grounding blade of each electrical receptacle,shall be not less than 115g (4 ounces).
Why does in an electrical plug the earth pin is longer than other two...what is its main function?
The earth pin is called the equipment grounding conductor. The National Electric Code requires this conductor to be the first to make contact with the receptacle and the last to break contact with the receptacle, the way manufacturers comply with this requirement was to make the pin longer.
Why is the ground wire smaller in your 8 2 with ground wire?
The grounding wire is not intended to be a load-carrying conductor in ordinary use, but rather a SAFETY conductor. Grounding wires are often "one size smaller" than the associated load conductors in the same cable.
What is a duplex grounded receptacle?
A duplex receptacle has two devices in a composite assembly on one yoke. It is the receptacle that is what you commonly think of as a receptacle [two places to plug in a lamp...] rather than a single receptacle, which has a place to connect one device. Removing the connecting bar as described in earlier answer merely allows two circuits or separate control of the two devices. original answer: a duplex receptacle is a normal looking receptacle but the little piece of copper bar between the terminal screws on the power side has been broken off and two different circuits feed the two screws- WRONG!
If you had a wall AC unit that ran on 240V and you got a new one that runs on 120V how do you change the wall receptacle outlet wiring to be able to run 120V instead of 240V and how about the breaker?
There are several factors: the outlet configuration and connection, the supply wiring, and the breaker. It has been suggested that: :The 240v gauge wire may be thicker than the 120 volt gauge. The 120 is 12 gauge and the 240 is probably at least 10 gauge. The wire itself will probably be okay. The outlet will have to be changed to a regular receptacle. The breaker for that circuit will have to changed to a 20 amp instead of the 30amp or so that it is now. I hope this helps you some. However, this ignores the fact that you can deliver twice as much power at 240v than 120v using the same rating wire and breakers. P= v x i; double the voltage, double the power for the same number of rated amperes. In any event, the cable into the breaker box will have to be disconnected from the two-pole breaker and the black (hot) wire connected to a single-pole breaker (say, 20A), and the neutral (white) wire connected to the neutral bar. There should also be a bare or green grounding wire connected to the grounding (or neutral) bar. The supply wiring must be at least 12 AWG or larger diameter (i.e., a lower number is larger diameter). In an ordinary north American receptacle, the black "hot" wire goes to the narrow slot, the white "neutral" goes to the larger slot, and the bare "grounding" wire goes to the third prong, often via the green screw marked "ground". Local code may dictate exactly how grounding connections are made (i.e., directly from the cable or with green pigtail from metal outlet box connected to the supply ground and the device ground). If possible, install a GFCI for added safety. Needless to say, any necessary rewiring of breakers and outlets should be done carefully by a qualified electrician, and you may need a permit, if not an inspection. It is also possible that someone illegally connected more than one outlet to the same circuit, so you should make sure there are none before any conversion project is undertaken, and account for any "extra" wires in the outlet box.

Why earth pin is thicker than live and neutral pin?
The earth pin is physically thicker to create a larger surface area. When it makes contact with the ground in the receptacle it is more positive and secure a contact. Also a larger surface area reduces the resistance between the two surfaces which is what is required in the grounding system.
An ordinary outlet should be calculated what?
For a home, to calculate the amount of receptacle outlets on a 15 amp circuit, each receptacle outlet should be calculated as not drawing more than one amp each.
What uses the 80-conductor cable with additional grounding and supports drives larger than 137 GB?

How can you test the grounding system on a power tool?
connect the cord to a grounding outlet get a variable current source connect it to the ground terminal on the receptacle and the frame of the tool if its a 20 amp circuit and receptacle it should take 20a thru the grounding system without any problems like wires overheating or measure from the ground terminal to the tool frame it should be lees than .5 ohm the ohm meter does not test the ability of the grounding system to conduct a fault to ground before the circuit breaker trips there are testers capable of doing this all automatically with the tool on and off if the ohmmeter is not capable of testing at 20A the test should not be considered reliable

Is sun one of the largest stars in the galaxy?
No. The sun is larger than the average star but is nothing out of the ordinary.
How are soup mugs different from ordinary mugs?
Soup mugs tend to be larger than ordinary mugs, with a wider lip. They're more of a cross between an ordinary mug and a bowl, and often are double-handled.
Is 0.2 greater than 0.1 and less than 0.3?
Yes
How could you differentiate between a supercell an ordinary thunderstorm cell?
The most distinguishing characteristic of a supercell is its rotation, which does not occur in ordinary thunderstorm cells. Supercells are also generally larger, stronger, and longer-lasting than ordinary storm cells.
What is unusual about the Sun compared to any other star?
There is nothing unusual about the sun. It is brighter and larger than average, but nothing out of the ordinary.
