The formula for current is Amps = Watts/Volts. The lamp itself would draw 4.16 amps. Since the voltage of the lamp is 12 volts there is a internal transformer involved in the fixture itself. It doesn't matter what the input (primary) voltage to the transformer is, so long as it meets the manufacturer's specification as to the proper voltage to operate the fixture.

It would be pretty much undefined, since the filament of the halogen bulb would fail immediately then there would be an open circuit with no current draw.

The pre wire for a ceiling fan light should be made with a three wire cable. This cable will have a red, black, and white wire as main conductors. This cable will also have a bare ground wire. This wire should be strung between a two gang switch box to the fixture junction box. This pre wire allows the supply to be either fed to the two gang box. From the two gang switch junction box, one side will be used for the light in the fixture and the other side of the switch junction box, itwill be used for the fan portionin the fixture.

Yes, if the manufacturer installed a parallel blade 15 amp rating cap on the end of the cord then just plug it in. The circuit that you plug into should be a dedicated circuit (nothing else on the circuit) because the amperage will be 13 amps at 120 volts.

If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.

Usually the rating of a welding machine is expressed on the DC output side. What you need to state is what the input in voltage and amperage is. It is this side of the welder that is connected to the supply breaker. On the nameplate there will be a voltage, amperage both stated for an AC supply connection.

A continuity test, just turn the lights on and if there is continuity the fixtures will let you know.

Depends on the output of the generator

No, that alone would not cause a GFCI to trip because that is the proper way to wire a panel.

a 220 volt, 3200 watt oven will draw under 15 amps, so yes a 2o amp breaker will work.

Yes, and sometimes are.

When initially installing them, you might have to add an additional 2"X4" horizontally with it, depending on the kind of box you get.

You will need two 3/way switches and two 4/way (Intermediate) switches. Click the link to see a video of exactly how to wire such a circuit.

A typical home hot water heater uses 4800 watts. The circuitry connecting to the tanks is a 20 amp breaker with #12 wire for the connection. The tank draws 20 amps. W = A x V = 20 x 240 = 4800 watts. Some industrial hot water tanks can be rated at four times the size of home tanks.

A 600 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated for 420 and 455 amps respectively. To reduce the wire size from a single conductor, a parallel feed of 3/0 can be used.

First and foremost is the electrical inspector. Second is the customer. Third is the electrical contractor. Fourth is the lending institute if a loan is taken out to do the project.

Zero.

Many outlets have small tabs between the terminal screws that can be broken out with a needle nose pliers. You can completely separate the continuity of the top outlet from the bottom outlet by breaking both these tabs and wiring each outlet as a completely separate circuit. The ground plug is the only line that cannot be separated this way, and will remain common for both outlets. Alternatively you can break a tab only on one side and have the outlet share either the neutral or hot line. For a outlet set up to have constant power on the bottom break the tab on the neutral side, wire your hot line as normal and the "constant" neutral to the bottom neutral terminal, then run a second neutral from your switch. This would allow for the bottom outlet to be live all the time and the top to be switched on or off.

A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.

Measure the ground resistance from the user end point, where earth or ground cable is connected. It will show a very high resistance or open if ground is broken.

Working space around electrical equipment shall be minimum: 30" wide and 36" deep and 6'-6" high. The panel door must be able to open at a 90 degrees angle.

Not a good idea in general. There is a large chance that you will trip what I expect is a 20 A breaker controlling the circuit. It may seem to work under some circumstances, but if the refrigerator compressor kicks in while the washer motor is demanding a surge current on motor start-up the breaker will likely trip.

Assuming you are working with 120v, you need #4 AWG copper conductors.

If you have the symbol for a regular switch, a 3-way switch is the same symbol with a '3' next to it like a subscript.

As a service entrance wire you need AWG # 3/0 gauge copper.
