How many watts is 60 Hz 5 amps?

That depends on how much voltage is applied, because Volts x Amps = Watts. So find out your Voltage and multiply it by the amperage to get your wattage. 60Hz is standard for AC (hence the term Alternating Current) and used for long distance power transmissions and even household currents. Usually what is coming out of the socket is around 120 Volts (240 for appliances and other countries). So applying this formula to this is simple: 120Vx5A=600 Watts or 240Vx5A=1200 Watts. So on...

How many amps does a hot tub draw?

That will depend on the size of the motor, number and wattage of the lights, heating capacity of the system... Each manufacturer decides their own specifications. You'll need to refer to the owners manual, installation manual or contact the manufacturer. ANS 2 - ALL the above is perfectly correct, but to simplify it a little. - Most of the hot tubs I see are 220v, and draw 7-9 amps for the pump and 22-25 for the heater. I work on many tubs and...

What color wire goes to the brass screw on the back of an outlet?

For a country using the USA standard house wiring color code: the black wire connects to the brass color screw.white to silver color,ground to green. The international standard for the "live" wire is brown, which would go to the brass screw, plus blue to the white screw, green/yellow to the green screw. In some cases, another color may also need to be switched, such as a red wire or a white (or blue) one in a three-way circuit. If white or blue wires are...

Does the ribbed wire connect to the positive or negative on a light fixture?

On a molded 2- or 3-wire line cord the ribbed conductor is the neutral conductor. On a polarized 2-prong plug it will be connected to the wider blade. On some line cords the neutral conductor may have a white stripe instead of ribs. ...

What is a one pole 2 gang switch?

Typically the number of poles represents the number of sources being switched. In a normal household ON/OFF light switch the single pole is the HOT wire (Black). The most common single pole switch is also single throw. The ON/OFF switch described above. This switch is abbreviated SPST. You could also have a single pole double throw switch (SPDT). and other variants on the same theme. The term gang is usually used to describe multiple switches in the same electric box. For example,...

Can you plug a 240v device into a 120v wall socket?

No, the device will not function properly. Some devices can operate on both voltages, a computer power supply for example. Most devices require a properly wired outlet connected to the correct voltage source. In the US most houses are supplied with 220/240 volt to their utility panel. An electrician can help you install an outlet for your device. Note: The above answer is correct. In addition, within the United States, cord caps, {plugs}, and receptacles, {outlets}, have unique configurations for various voltages and currents that...

How do you replace dining room light fixture?

Answer for USA, Canada and countries running a 60 Hz supply service. Turn off the power to the light at the main circuit breaker panel. You will be working on a ladder if light is on ceiling so be careful. A non metal ladder is preferred when working with electricity. Remove the fixture such that the wires connecting it to house power are accessible. In some cases it might appear that the fixture could hang from the wires coming from the ceiling, but...

What size wire should you use for 1000 amps?

There are a couple of choices. Single conductor is out of the question as it is physically too hard to work with. That type of current handling capacity is done with bus bars using bus trough. Parallel and triple runs of conductors is the more likely scenario Parallel runs of 750 MCM or triple runs of 400 MCM will give you a total ampacity of 1000 amps. A 750 MCM copper wire is rated at 500 amps and a 400 MCM...

What is the difference between 10 awg and 12 awg speaker wire?

10 AWG wire will have less resistance per foot and therefore you can have longer runs with 10 AWG than 12 AWG without as much loss of signal. Additional to loss of signal there is a need to maintain a low impedance driving the typical speaker with its 4 ohm or 8 ohm coil resistance, to avoid frequency-distortion. A guide rule is that the speaker cable should have a total resistance around 1% of the speaker resistance (or less). On that basis,...

What does 12 amps resistive load mean?

A resistive load just describes something like a toaster, electric water heater or space heater, where the load is relatively constant. The description is used to distinguish from something like an electric motor, which uses much more current at startup then drops off significantly after it is running. Answer In a.c. circuits, a resistive load describes a load whose load current is in phase with its supply voltage. Expressed another way, it is a load having unity power factor. Resistive loads are not necessarily...

Why does your circuit breaker blow when you use your washing machine?

Your washing machine should be on its own dedicated circuit. When it runs it draws current. If the current exceeds the breaker rating the breaker will trip. You didn't say anything about the circumstances so it is hard to pin down the cause. Some possibilities are: 1. A bad breaker. 2. There is some obstruction or binding on what the motor is trying to turn and it stays in an over-current start up mode trying to overcome the mechanical loading. 3. There is a...

Can you plug a 30 amp plug into a 40 amp outlet?

Yes and only if the device connected to the 30 amp plug draws no more than 30 amps. <<>> No, the configuration of a 30 amp plug will not fit into a 40 amp outlet. This for a safety reason that they make different configurations of plugs rated at specific amperages. A 40 amp outlet is protected by a 40 amp breaker so the wire will be be able to carry 40 amps before the breaker will trip. The maximum amount of current...
