New Electrical Work

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.

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.

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.

A mercury vapor lamp puts out a greater percentage of its energy as light compared to an incandescent lamp. Mercury vapor lamps are more efficient at converting energy into light, whereas incandescent lamps produce more heat than light, making them less energy efficient.

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.

Electricty runs in a loop from neg to pos (in DC). From your question, it appears you're talking about AC. If it is single-phase, it still runs in a loop, so it *SEEMS* from your description that it would not be additive.

Best to draw a diagram of what you're measuring when you say "measured amps on both legs" and resubmit the question before I give you a 100% answer.

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.

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.

The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals.

If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.

#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.

No, because 100 v at 1 amp is a supply of 100 watts of power. It could be turned into a 25 v supply using a switch-mode voltage converter, but the available power would still be theoretically no more than 100 w, which is 4 amps at 25 v. In practice it would be slightly less.

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.

You would need at least 3 AWG at 120 volts, giving you a 4.8 percent voltage drop at the maximum load of 37.5 amps (using 30 Amps at the ordinary 80 percent rated capacity of the circuit). For 240 volts you would only need 6 AWG.

The provisioning of the breakers in a panel has a physical limitation regarding how many breakers will fit and a load calculation based on what devices the panel has to support. Your question really applies to both types of breakers. There are rules of thumb for sizing and populating the panel. This information is in the National Electric Code. If you have an existing panel and a new application requiring additional breakers for 220 Volt applications, the current draw in panel can be measured by an electrician and you will know what additional load you can support. If breakers fit physically in the panel, but connected devices exceed the total current capacity you will trip the main panel breaker. At this point you would need to get an electrician involved.

No, a 27 amp start-up on a 15 amp circuit breaker can potentially overload the circuit and cause it to trip. It's recommended to use a circuit breaker that can handle the full current draw of the device to prevent tripping and ensure safety.

When buying a distribution panel look for the capacity rating of the bus. There are some panels that have a 100% rating and others that only have an 80% rating. This rating is reflected in the price of the panel. The least expensive panel might not be the right one for your application.

There are many types of three wire and four wire cables. There are many types of armoured sheath on these cables. The cables can have free air rating like NS75 quad, or hard drawn single conductor rack mounded conductors. The voltage rating of the cables plays a big part in the price of the cables. So to give a definite price without knowing more about the cable, a price can not be given.

A 1250 MCM copper conductor with an insulation factor of 90 degrees C is rated at 645 amps. If you have ever worked with these sized conductors you would know that it is nearly impossible to bend, let alone pull it into a conduit. Seeing how the conductor size is over 1/0, it can be paralleled up to smaller size conductors to meet the ampacity requirement. The options are, parallel 350 MCM, triple parallel #2/0 or quad parallel using #1/0 size wire. These wires are terminated in double, triple and four barrel lugs respectively. It has to be kept in mind that as the amount of wires increase, so does the conduit diameter size, to accommodate the conduit fill code rule.

# 4 gauge THHN or THHW is rated for 95 amps and would normally be the correct wire size. However, at 300 ft. from the source, you definetely will have a substantial voltage drop. Therefore, you need to up the conductor size to # 3 gauge.
