What size SER cable to use for 375amp load?
A 400 MCM copper conductor with an insulation temperature factor of 90 degrees C is rated at 380 amps.A 500 MCM copper conductor with an insulation temperature factor of 75 degrees C is rated at 380 amps.These conductors can have either 600 or 1000 volt insulation rating depending on what the system voltage in use is.
Does using transformers to create high voltages reduce wasted energy in power lines?
Yes. The two main reasons are:For a given size of power line more power can be carried by the line at higher voltage and lower amperage with less resistive heating. The heating due to resistance is a waste of energy. This due to Power = Volts X Amps. The higher the Volts the lower the Amps for some amount of Power. The more Amps carried by a conductor the more heat it will produce due to resistance.Since we can use a smaller size of power line to carry a given amount of power we will use less copper or aluminum to make that power line. The less material we use to make the conductor the less energy we have to use to make that conductor. Also the less energy it takes to transport, install, and support that conductor.
Why unity power factor is used in load test?
When power factor is at unity, the voltage and current waves are aligned or in phase with one another. Since power is the product of voltage and current, power transfer is maximized at unity power factor. When power is transmitted at a lower power factor, greater current is required to deliver the same amount of power. When current is increased, the size of the transmission, distribution and generation systems, all have to be increased accordingly, along with the price of the killowatt-hour at the meter.
Which conductor size has the largest diameter?
The largest conductor listed in the National Electrical Code is a 2000 kcmil.
What size power cable is needed for 30KW 440V 3phase 50Hz induction motor?
Use this formula to find amperage when kW is shown. Amps = kW x 1000/1.73 x Volts x pf. Use a power factor of .85 for the formula. Once the current is calculated re-ask the question for cable size for the calculated current.
What is wire factor of All almunium steel reinforced conductor size 0.176 S.W.G?
What is wire factor of almunium conductor steel reinforced size 0.176 S.W.G?
Which is a factor that effects the size of mineral crystals formed in magma?
fluoresence is not a factor. I had this same question and i got fluorescence as a correct answer
What are the specifications and size of a motherboard or power supply?
The "form factor."
What size conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
What size cable for 125 amp sub panel?
A #2 copper conductor with an insulation factor of 90 degrees C is rated at 130 amps.
What is the minimum cable size required for 400Amps incoming supply?
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.
How do you measure the size of a power adapter?
The size of a power adapter is typically measured by its dimensions in millimeters or inches. This includes the length, width, and height of the adapter. Additionally, the power rating in volts and amps is also an important factor when considering the size of a power adapter.
What is the correct wire size for 40Amp range?
40 awg <<>> The above answer is incorrect. A #40 wire is smaller that telephone wire which is #22 awg. A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps. For a built in safety factor, a #8 conductor with an insulation factor of 75 or 90 degrees C has a rating of 45 amps.
What Wire Size needed for 40 amperage circuit breaker?
A #8 copper conductor with a 90 degree C insulation factor is rated at 40 amps.
How many amp is aluminum wire size 6 good for?
A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
Which is not a factor that effects the size of mineral crystals formed in magma?
The composition of the minerals is not a factor that affects the size of mineral crystals formed in magma. The factors that do affect crystal size include cooling rate, amount of water present, and amount of pressure.
What size of wire do you use from a 460 amp battery bank to an inverter?
A 700 MCM conductor with an insulation factor of 90 degrees C is rated at 500 amps. A 4/0 copper conductor with an insulation factor of 90 degrees C is rated at 235 amps. Parallel them up for a total of 470 amps.
