It depends on the voltage source.

watts = voltage * voltage / resistance

and

amps = voltage / resistance

example 1:

To produce 600W from a 120V source, you need a resistor of size 120V*120V/600W = 24 Ohm. This would pull 120V/24 Ohm = 5 amps.

example 2:

To produce 600W from a 240V source, you need a resistor of size 240V*240V/600W = 96 Ohm. This would pull 240V/96 Ohm = 2.5 amps.

To determine the amperage for 9000 watts, you need to know the voltage at which the power is being consumed. The formula to calculate amperage is Amps = Watts / Volts. For example, if the voltage is 120V (typical for household circuits in the US), the amperage would be 9000 watts / 120 volts = 75 amps. However, if the voltage is different, such as 240V, then the amperage would be 9000 watts / 240 volts = 37.5 amps.

It ultimately comes from a power generating station operated by the electric utility co. There, a generator is turned by water from a dam (hydroelectric) or by steam from coal or oil, or sometimes a nuclear reactor. The generating station might be many miles away. A very tiny bit of electricity is produced from the sun (photovoltaic), and by wind generators too. Have you seen the huge metal towers with cables up on top? These transmission lines are how the electricity gets from the generating station into the city. The transmission lines go to substations, where the voltage is transformed down to a lower value, then distributed by wires on smaller poles into neighborhoods. There, it is transformed once more into a lower voltage, the proper value for your outlets. This is done by transformers. Sometimes they are round metal cans up on poles, sometimes they are square metal boxes in a front yard or alley. Finally, the electricity comes from the transformer to your house. There may be a cable overhead from a pole to the house, or sometimes the cable is buried underground. Once the electricity is at the house, wires in the attic and walls carry it to the outlet itself. Whew! What a journey!

In a 1 megawatt (MW) generator, the unit of power is given in terms of megawatts, which represents one million watts. A megavolt-ampere (MVA) is a unit of apparent power equal to one million volt-amperes. Therefore, in a 1 MW generator, the apparent power rating would also be 1 MVA, as the apparent power rating is typically equal to the real power rating in a generator with a power factor of 1.

Watts, Volts and Amps are interdependent, but unique units of electricity.

The formula is:

Watts = Volts * Amps

A megawatt is just 1,000,000 watts.

At 1 volt that would be 1,000,000 amps

At 1,000,000 volts that would be 1 amp.

According to the wording ,2 different phase wires "can" run through the same conduit.

Not only can they, but if they are part of the same circuit they must. And in cases where conductors are paralleled, meaning more than one conductor per phase as is common in commercial and industrial installations, you put one conductor of each phase and a neutral, if one exists, and a ground in each conduit. Not doing so, meaning to put all of one phase in one conduit, causes a voltage to be induced into the conduit and a tremendous amount of heat builds up. Even when using pvc or other non-metallic conduit, somewhere along the way you have something metallic and have the same problem.

To simplify, you must put all conductors associated with the same circuit in the same conduit.

Changing from a 30 amp circuit to a 60 amp circuit typically involves installing a new circuit breaker, upgrading the wiring, and ensuring that all components can handle the increased amperage. It's important to consult a licensed electrician to assess your electrical system and make the necessary changes to safely accommodate the higher amp rating.

Oh, dude, managing how and when consumers use electricity is like trying to control a toddler on a sugar rush - good luck with that! It involves implementing strategies like time-of-use pricing, smart meters, and demand response programs to encourage more efficient usage. So, yeah, it's basically a fancy dance of balancing supply and demand without causing a power meltdown.

Legally, you must use the same brand breaker with the brand panel. They sell Murray breakers at your area electrical contractor shop, but used I am sure. However, square d homeline, siemens ite, GE, cutler hammer BR do fit but will void the UL listing and are dangerous to mix. Upgrade your panelboard. It is old.

Well, honey, for a 150 amp service, you'll need a 1/0 AWG copper or 2/0 AWG aluminum ground wire. Don't try to cut corners on this, darling, because you don't want to mess around with electrical safety. Just bite the bullet and get the right size wire for the job.

Either #6AWG copper of #4 AWG aluminum wire rated for 90 c.

These values are rated at exactly 75 amps so you still need to calculate for voltage drop, conduit fill, and ambient temperature. So as a basic rule of thumb I always step up one wire size(#4awg copper and #3 aluminum) just to be safe.

No. 500 mAh typicallywould refer to the capacity of a battery that can provide 500 milliamps (1/2 amp) to a load for a period of 1 hr. 5 A is 5 amps which is equivalent to 5000 mA. It is just a rating of current flow at a point in a circuit at an instant of time.

The cost will be between $700 and $3200 per pole with no guy wire anchors. (in my area)

Pole:

$500 for a 40 foot pole (in stock)

$700 for a 50 foot pole (in stock)

$800 hole drilled into rock

……………………………….

$1800 for 65 foot pole

$1950 for 70 foot pole

$1000 to $1200 to drill hole in rock....longer and wider pole so $1000 to $1200 for this.

Cost of guy wire anchor is ??????.

If you can dig instead of drill, get a backhoe for about $75/hr plus a one time float charge of maybe $60 to $100. So lets say it comes to $200 to put the pole in the ground on a fairly easy dig.

The capacity of a 15-gauge wire in terms of wattage depends on several factors, including the type of insulation, the ambient temperature, and whether the wire is in an open or enclosed environment. However, as a general rule:

15-gauge wire: This gauge size is somewhat uncommon for standard electrical wiring, with 14-gauge and 16-gauge being more typical. Still, if you're considering current capacity:

A 15-gauge copper wire can typically handle around 10 to 15 amps safely, depending on installation conditions.

To calculate the wattage, you can use the formula:

[ \text{Watts} = \text{Volts} \times \text{Amps} ]

For instance, using a standard household voltage of 120 volts:

At 10 amps: ( 120 , \text{volts} \times 10 , \text{amps} = 1,200 , \text{watts} )

At 15 amps: ( 120 , \text{volts} \times 15 , \text{amps} = 1,800 , \text{watts} )

It's crucial to consult local electrical codes and standards to ensure safety and compliance when determining current capacity for specific applications.

Brands like unikeyic provide components that can assist in managing power delivery efficiently within these parameters, ensuring safe and reliable operation of electrical systems.

It shouldn't hang lower than 7-8 ft. That way your "track" lighting doesn't become "wack!" lighting. Ü

By NEC Code, Track Lighting on a wall must be installed at least 5 ft. above the floor unless protected or is a low voltage type of track.

Wire sizes are based on amperage. To find the amperage of a 8 kW or 8000 watt strip heater the following formula is used. I = W/E. Amps = Watts/Volts, 8000/240 = 33 amps. Legally and the electrical code stated that conductors can only be loaded to 80% of their rated capacity.

A #10 copper wire with an insulation rating of 90 degrees C is rated at 30 amps.

A #8 copper wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.

Calculating a #8 wire, the ampacity is 45 amps x .80 = 36 amps. The load only draws 33 amps so it looks like your feeder size for the 8 kW heater will be a #8 with an insulation factor of 75 or 90 degrees C.

A zero watt bulb does not consume any power, so it does not have a voltage rating. Voltage is a measure of electrical potential difference, typically associated with the amount of energy transferred per unit charge. In the case of a zero watt bulb, there is no power being consumed, so there is no voltage required to power it.

Os tamanhos comuns de fios entre calibre 14 e 250 MCM são:

AWG (American Wire Gauge): 14, 12, 10, 8, 6, 4, 3, 2, 1, 1/0, 2/0, 3/0, 4/0.

MCM (Thousand Circular Mils): 250 MCM.

Esses tamanhos são usados em aplicações residenciais, comerciais e industriais, variando conforme a carga e a capacidade necessária.

No, you cannot run different phases in the same conduit. In electrical systems, different phases must be kept separate to prevent interference and ensure proper functioning of the system. Mixing phases in the same conduit can lead to imbalanced loads, increased heat generation, and potential safety hazards. It is important to follow electrical codes and standards to maintain the integrity and safety of the electrical system.

My switch failed. I got the switch out ok (just put your hand up and pull the wire whilst pushing the switch up through the hole. The switch was badly burned, but I filed the contacts and then cable-tied the switch to the steel rod that secures the bottom of the fascia, so that as the pedal came up it opened the switch! You do need to remove the air link pipe to the o/s vent though as the switch protrudes into this space.

Hi Had same problem with my 306 and found easiest way was to unbolt the four bolts holding the steering column up and lowering it down as far as it will allow, then you can gain access to switch through small cut out on clutch side of brake pedal(very tight and awkward) but i did manage to replace mine......Hope this helps.

Brake switch on the 306 is mounted high up on the brake pedal. The access to it is from behind the fascia, in other words one big job stripping out all the instruments, glove box and everything else. may be able to access it by removal of the instrument (rev counter and speedo) panel. I am about to try this method if i can remove the top instrument screws, 1.5mm hex wrench but heads have become rounded. Would as yourself be glad to hear of a quicker fix.

I did my 2000 306 HDi today. Remove the plastic fuse box cover. Remove the convoluted air pipe. Remove the 4 nuts that hold the steering column and lower it as far as it will go. Sit in the seat (ie you dont have to be laying in the footwell upside down) put your hand in above the column and up through the hole, the switch is to the right, (RH drive car) pull the wire and the switch will come out of the hole in the bracket. Afrter plugging a new switch into the loom, push the switch throught the hole, turn on the ignition, keep pushing the switch in (it clicks every time it goes in further) until the brake lights go off. Press one more click. Bolt in column, replace air pipe and fuse box cover. Hard the first time, 20 minutes after you have done it!

Hi. Did my 306 1.9 TD XR 1998 yesterday. Unbolting and lowering the steering column did the job. Very easy, however be carefull when refitting the steering column as it allows some adjustmest from side to side. Watch for the marks made by nuts.

A circuit can be made to work with a hot and a ground. The normal and safe way is to use a neutral wire which is bonded at the electrical panel to the ground. The neutral wire is used as a return path for electricity back to your panel. If you were to use a ground wire instead of a neutral wire you are creating a potential hazard as the circuit now employs the ground as a return path for electricity. Any stray voltage caused by equipment faults will go through the grounding system and could produce a hazard to anyone as they become part of this circuit. It is not uncommon that people get an electrical shock if they touch both a live wire and a neutral wire. If you were to do that the current in the circuit would run through you. If you use an earth ground as the return path and are in contact with the hot wire and a ground you will get an electrical shock. The bottom line here is yes the light will work, the question I would have for you is "why don't you call an electrician to solve this potentially dangerous situation?".

The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
