Modification of Old Electrical Work

The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.

No. In North America a double pole breaker is used to obtain a voltage of 240 volts from the distribution panel. What ever the amperage rating stamped on the handle of the breaker is, that is the amperage that the breaker will trip at.

It depends on the amount of current (Amps) your breaker is rated for. If you boost your voltage the current will go down proportionally. 10 guage wire has an allowable ampacity of 30A. so if you are not drawing more than 27A you should be ok.

For a 5 amp load at 120VAC, you can use a 18-gauge wire for general use. However, it's always recommended to consult local electrical codes or a professional electrician to ensure proper wire sizing for safety.

If the ceiling light doesn't have a black or white wire, it may be designed for specific installations or may use different color coding. In such cases, refer to the manufacturer's instructions or consult a qualified electrician to correctly identify and connect the wires. Never attempt to make assumptions or modifications without proper knowledge to avoid safety hazards.

The red wire is typically used for the live or hot wire, and the black wire is commonly used for the neutral wire. The specific wire connections may vary depending on the electrical circuit, so it's important to consult a professional electrician for proper installation.

You should never hook a generator to any house outlet, no matter the current. I assume you are looking for a quick and dirty way to connect a generator to your house in a power outage situation. This should only be done through an approved disconnect switch.

From a purely electrical perspective, most items will run just fine if the hot wire and neutral are reversed. I like to say the electrons don't care. But any protection built into a piece of equipment is wired into the hot wire and you subvert this protection if you reverse the wiring.

In a light fixture, the NEC requires the neutral wire (usually white) be connected to the screw shell of the socket. This prevents the screw shell from being energized and it is the most accessible part when changing bulbs. If properly wired, the hot part of a socket is the "button" in the very bottom of the socket.

There are some items that require proper wiring and the only way to ensure this is done is to do it right every time.

Another way to explain it is, using a vacuum cleaner as an example, if the wiring is correct, the hot wire goes to the switch and only when the switch is on is the vacuum cleaner energized. If the wiring is reversed, all the wiring in the vacuum cleaner is energized even when the switch is off.

No, it is not recommended to use a 70 watt metal halide lamp with a 150 watt ballast. The lamp and ballast wattage should match to ensure proper operation and to prevent damage to the lamp or ballast. It is best to use a compatible lamp and ballast with matching wattages.

The maximum amperage of a 0 gauge wire typically ranges from 150 to 200 amps for automotive applications. However, it is important to consult the specific manufacturer's guidelines and consider factors such as temperature and installation conditions to ensure the safe use of the wire.

For a 25 amp circuit over 420 feet, you would typically need a 10 gauge wire to ensure minimal voltage drop and proper safety. It's always recommended to consult with a qualified electrician to determine the best wire size for your specific situation.

The difference is safety. Any appliance or equipment that has metal parts that may be touched by the user will usually have 3 prongs because this provides for safety if those metal parts become energized. Exceptions would be "double insulated" items, such as many power tools, and items without exposed metal parts.

In a typical US automobile, a 30 amp fuse will sustain a constant load of 360 watts.

Fuses and circuit breakers perform on an "I squared t" rule. For example, a 30 amp fuse will not blow on 31 amps for a very long time. A 20 amp breaker can take anywhere from 10 minutes to two hours to trip on 25 amps. We simply dumb it down so that laymen and technicians need not make mistakes.

Power on seven 100 watt light bulbs simultaneously. That means a circuit suddenly provides 50 amps. 50 amps does not trip a 15 amp or 20 amp breaker, again, due to the "I squared t" rule. A 50 amps load only exists for tens of milliseconds. Not long enough.

A 30 amp continuous appliance will not trip a 30 amp breaker. But a safety margin means limiting 30 amp appliances to 26 amps or less.

Meanwhile, an 18 gauge lamp cord wire typically rated for 10 amps will actually conduct up to 50 amps continuously. Again, that wire is oversized for other safety reasons. And to keep it simple.

These concepts apply to fuses vehicles and structures.

At 240 volts, and 7 amp current, you will have a load of 1680 watts (volts x amps = watts). A 2000 watt generator will sufice, however a 3500 watt generator, if within your budget, will power a few other necessities if required.

To control a ceiling-mounted fan from seven locations, you would need a minimum of three four-way switches. Each four-way switch allows you to control the fan from three different locations by working in conjunction with two three-way switches.

Yes, it matters which black wire is connected to red. Ensuring the correct connection is important to avoid electrical issues or malfunctions. Make sure to connect the black wire properly according to the specific instructions provided.

The red wire is typically used for connecting the live or hot wire in an electrical circuit. It helps to safely transmit power to the switch, allowing for control of the connected device or appliance. It is important to follow proper wiring procedures to ensure the switch functions correctly and safely.

NO!

If you're running a 40 amp circuit you must use 8AWG wire. If you attempt to use anything smaller you run a significant risk of burning your house down.

If you are unfamiliar with wiring regulations and practices, contact a qualified electrician to wire the circuit for you.

For a 5kW heater HVAC system, you would typically need to use 10-gauge wire to handle the current load safely. It's important to always consult the manufacturer's specifications or a licensed electrician to ensure you are using the correct wire gauge for your specific setup.

I'm not sure of your question here. If you are asking if you can replace a fuse with a fuse with a higher voltage rating, the answer is yes, but it probably won't fit in the same terminals. The voltage rating must be the same or higher than the voltage applied.

#10 wire is good for 30amps; however it is wise and sometimes required to use an 80% load factor. If you need 30amps continuously you would want to use #8 wire, which is good for 40amps. #8 wire could safely run 32amps continuously, 40amps x 80% = 32amps.

You failed to state the input voltage.

To calculate the amps, use the formula:

Amps * Volts = Watts

X * volts = 6000

(If we guess at 12 Volts)

X * 12 = 6000

X = 6000/12

X = 500

Which is a pretty big fuses, but to make matters worse, you would need to add about 10% or more for power lost to the inefficiency of the inverter.

A 600 Amp fuse is an industrial device; hope you're planning on expensive.

The 6000 watt rating will be the output wattage usually at 120 volts. 6000/120 = 50 amps. If the output is a three wire output at 240 volts the amperage will be 25 amps. For a 50 amp circuit a #6 copper conductor will be needed from a 60 amp breaker. For a 25 amp circuit a #10 copper conductor will be needed 30 amp breaker.
