No, just black on brass colour and white on silver colour screws. If you look closely you will see what is called a tie bar connecting the two screws together.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
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.
No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.
A 220 receptacle has 110 on 2 blades and the other blade is a ground.
Technically, 110-volt and 120-volt receptacles are not exactly the same. However, in practical terms, they are often used interchangeably as the standard voltage in the United States has become 120 volts. Most modern appliances are designed to work within a range of voltages, so a device rated for 110 volts should work fine in a 120-volt receptacle.
In North America on a 120/240 volt home electrical system, the ground pin on a duplex wall receptacle is on the bottom.
If your electrical service is only 120 volts you have a problem. There is no way that you can connect a 240 volt cook top to that service. You have two options, one is to upgrade to a new 120/240 volt electrical service. Your other option is to find a 120 volt electrical cook top.
YES, and the actual power is 117VAC not 120.
If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
Yes, you will need a special plug for a 120 volt 20 amp circuit. The plug should match the configuration of the receptacle to ensure proper connection and safety. Consider consulting with an electrician to determine the appropriate plug for your specific circuit requirements.
You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.
Up. ---- I'm not sure what the question is getting at. USUALLY THIS QUESTION IS ASKED WITH REGARD TO THE "GROUND" PRONG of a standard 3wire, 120 volt receptacle In the USA there are no requirements which dictate whether a receptacle outlet should be mounted with the ground UP or DOWN. In fact, it is also proper to mount the receptacle horizontally.
