Electrical Wiring

Use the formula I = W/E, Amps = Watts/Volts. Apply the voltage of the generator to the formula and the results will be the amount of amperage the generator will produce.

It is not recommended to use a 12 volt power pack on a 9 volt keyboard as it may damage the keyboard due to the higher voltage. It is important to match the voltage requirements of the device to the power source to prevent any issues.

in the olden days, electrical engineers figured if you drop razorblade or pin between the receptacle and the plug, the metal will get in contact with the ground prong thus minimizing the chance of energizing a metal object. this is why most outlets in schools and hospitals are installed ' upside down". nowadays we install them 'downside up' to see a smiling face. ha ha.

The 120 volt equipment is likely to burn up or burn out sooner. The filaments in a 120 volt bulb will burn a lot brighter for a much shorter period of time. That is how movie studios used to produce a lot of light without using expensive equipment. They would replace light bulbs every day. Electric motors would be far more powerful and run hotter. Movie studios used them for special effects. They did not care if an elevator took off like a rocket once and burned out the motor.

There is no mention in the CEC as to which way a receptacle is to be positioned. The most common way is to have the ground pin in the down position. This way, if something drops on the plug (cap) when it is in the receptacle, the last pin to disconnect will be the ground pin. Some manufactures of appliances have 90 degree plugs (caps) installed on their equipment to present a low profile when in the receptacle. The ground pin in these types of caps is positioned to the top and the hot and neutral blades are below it. On connections like this the receptacle is mounted with the ground up to allow the appliance cord to drop down when it is plugged in. Still other applications will find the receptacle mounted sideways, usually in the back splash of kitchen counters when there is an absence of space to mount them vertically.

The metal prongs of a plug are sealed in plastic or rubber to provide insulation and protection against electric shock. This covering helps prevent accidental contact with the metal prongs, which carry electricity, making the plug safer to handle and use.

It is to prevent electrical shocks.

If you have a 208Y/120 volt 3 phase system, you can use any one of the three phases (hot or ungrounded conductor) with the neutral for 120 volt load or you can use any two phases of the three phase for a single phase 208 volt load.

If you have a 120/240 volt 3 phase system, you can use any two phases of the three phase for a single phase 240 volt load or you can use either the A phase or C phase with the neutral for a 120 volt load. You can not use the B phase with a neutral (you would have 208 Volts!).

You can use a step-down transformer to convert three-phase 600 V to three-phase 380 V. The transformer should be rated for the desired output voltage and capable of handling three-phase connections. Make sure to consult with a professional electrician or engineer when designing and implementing this conversion.

Phase voltage is determined by the wiring of transformer that serves the building. To test phase voltage use a volt meter and put one probe to ground and the other to each phase and observe the reading, this will give you a phase to ground voltage reading. Next test phase to phase (1 to 2, 1 to 3, and 2 to 3) to see if it's 208, 240, 277, or 480. Only licensed electricians should perform these tests. DAW

This is something that should not be done. If this was to be done you would be omitting

the ground which in point can make it unsafe. I recommend changing the female end of the system and making it a 4 prong.

I am trying to find out myself, having found odd harmonics coming thru the neutral wire with my breakers open...I've been trying to identify the source of a strange hum/vibration in my home.

If you mean the NEC, they have no power over electrical utilities.

Your in home neutral wire should be at ground potential so there should be 0 volts to ground.

Draw a battery and light bulb. Draw a line from the smaller connector on the battery

to the bottom of the light bulb, this is positive on both.

Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both.

Looked all over and can't seem to find this one.

Circuit breakers are more convenient as they can be reset after tripping, whereas fuses need to be replaced. Circuit breakers also provide better protection against electrical overloads and short circuits. They are considered safer and more reliable than fuses for modern electrical systems.

If you unplugged the breaker and put it on the table and it tripped then it would be related to the internal mechanics of the breaker being under some tension causing it to trip. This is just to illustrate what it means to be really disconnected. What is likely is that somewhere in the circuit the Hot wire is shorted to neutral or ground. If you know where all the outlets are on the circuit you can disconnect them one at a time and see when the problem goes away. This can be dangerous if you don't know what you are doing. An electrician would have a meter and signal tracer that could find the problem much quicker and safer.

One way an electrican might troubleshoot would be to remove the black wire from the breaker in panel and test resistance with a Volt=Ohm-Meter (VOM) to verify there is a short, and then trace the circuit through each outlet to find the short. The short could be internal to an outlet or switch, a short to a metal box, a screw or nail in the wire hidden in the wall, or any number of other reasons.

It may work but may be brighter than the rating stamped on the bulb or the filament may burn out very quickly, depends on what sort of bulb it is, wherhet is uses a ballast or some form of regulator etc.. its probably best not to try unless your positive it is designed to take double the voltage

Glass is one of the best insulating materials there is. It is used for insulators on power line to isolate the energized lines from the poles that support the wire. As the voltage increases the insulators can be ganged together to increase the insulation factor.

Ocean currents can be measured using instruments such as current meters, Acoustic Doppler Current Profilers (ADCPs), and drifting buoys. These devices can provide information on the direction, speed, and depth of ocean currents. Remote sensing technologies, such as satellites, can also be used to measure surface currents over broader areas.

Green wire must be grounded for safety. The two white wires are phase and neutral.

You can discover which one is the hot wire by using a mulltimeter. But there is no needing to discover it. About the green wire only an electrician can install it properly.

It can be joined to the neutral wire, but it is not advisable for any electrical device. The correct procedure is to connect the ground wire on the recommended manner. Normally lamps do not need to be grounded.

There is a short somewhere in the line. Start at the outlet end and what is plugged into it and work your way back. If it is a GFI breaker, they can be bad and trip as soon as any drain is put on them. I have had them trip as soon as a drill is plugged in without even turning on the drill.
