How many amps does a 3000w inverter 240 v draw from a 12 volt system?
It would be at least 250 amps, maybe 300 amps.
How many amps is 250 MCM wire good for?
300 Amps if used for service entrance conductors. Table 310.15
Why a 5amp. rating ammeter is connected to secondary side of current transformer?
The maximum current output of a CT is 5 amps. Connected to a meter this will be full scale. What ever the ratio of the CT will dictate the scale face on the meter. A 500 amp CT's output will be 5 amps at 500 amps on the buss. 250 amps on the buss, the CT will output 2.5 amp or half scale on the meter face.
What wire size for 15000 Volts and 550 amp service?
There are two distinct questions here. To determine the wire size to carry 15000 volts the circuits load amperage must be stated. The wire size for a 550 amp service is, an 800 MCM copper conductor with an insulation factor of 90 degrees C. This conductor is rated at 555 amps. Parallel 250 MCM will give you a total capacity of 580 amps. A triple run of 2/0 will give you a total capacity of 585 amps.
What size wire for 250 amp service with a 175 foot run?
4/0 (4 ought) in copper will handle 250 amps. The voltage drop at 175 ft. is about 2.14 volts which should be okay.
How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
How do I make a 30 amp 250 volt line output only 220 volts at 30 amps?
you get a transformer...
How many amps in 250watts at 12volts?
250 watts divided by 12 volts = amps or around 20 amps
How many amps is 250 mA?
There are 1000mA in one amp. So there is 0.25 amp in 250 mA.
250 watts is how many amps?
Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.
How many amps would a slow cooker at 250 watts pull at 110 volts?
About 2.25 Amps.
How many amps will a 750kva electrical transfromer carry?
It depends on the incoming primary voltage. For a 5kva utility transformer receiving 15,000 volts on the primary the current drawn would be one third of one amp to give you an output of 5,000 VA (watts). Just remember this, volts x amps = watts or volt amps.
How many amps does a 3000w inverter 240 v draw from a 12 volt system?
It would be at least 250 amps, maybe 300 amps.
How many 200 amp panels can you tap off 250 kva transformer?
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
How many amps is 250 MCM wire good for?
300 Amps if used for service entrance conductors. Table 310.15
What is the amperage of a standard power outlet in China?
10 amps 250 volts or 16 amps 250 volts.
If a voltage transformer has turns ratio 5 to 1 Which side has a larger wire?
Lets put a value to the transformer, say 500 VA. Step down with a 5:1 ratio. Say 250 volts on primary. 250/5 = 50 volts secondary. 500 VA transformer/50 volts secondary = 10 Amps. Therefore the secondary would have to have the larger wire to accommodate the larger current.
