Apprentices of mine have been taught not to do this. This comes under the same heading as taping wire nuts. It tends to make a mess a few years down the road when things have to be changed and the tape becomes all gooey. The manufactures of outlets know what the clearances to the boxes that their equipment gets installed into and UL or CSA has approved their use and clearances to grounded objects. The only reason that it is done is to stop the outlets terminals from shorting on the outlet box when the device is removed "hot". If proper safety techniques are in place the device should never be removed "hot" in the first place. If the circuit was de energised in the first place, taping the terminals would be redundant.
What else can I help you with?
What size main breaker feeding 480v 75 kva transformer?
An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
Can a 1500KVA transformer feed a 1600A 480V service?
No, a 1500KVA transformer is not large enough to handle a 1600A load at 480V. The transformer should have a higher kVA rating to support the current demand of 1600A. A transformer with a minimum capacity of 1920KVA would be needed for this application.
How do you get 480v circuit from 120v?
You can use a step-up transformer. Transformers are rated in primary voltage, secondary voltage, kVA, phases (single and three) and other parameters then equipped with indoor and outdoor enclosures. Be sure to consult a professional engineer or electrician when choosing and installing a step-up transformer. There are several NEC issues involved as well as choosing a transformer that is right for the type of load you have. One without the proper licensing AND knowledge of transformer circuits should never install 480V wiring or transformers.
How many kw in 480v?
To calculate the kilowatts (kW) when given voltage (V) and current (I), you can use the formula: kW = V x I x √3 / 1000 For 480V, the calculation would be based on the current flowing through the circuit.
How many amps can you get from a 500Kva transformer?
The amps you can get from a 500 kVA transformer would depend on the voltage of the transformer's output. To calculate amperage, you can use the formula: Amps = Power (kVA) / Voltage. For example, if the output voltage is 480V, you would get approximately 1041 amps (500 kVA / 480V).
How do you wire 240V to 480V dry type transformer 15kw?
To wire a 15 kW dry type transformer for a 240V to 480V configuration, first ensure that the transformer is rated for this voltage conversion. Connect the primary side to the 240V supply by connecting each of the two primary terminals to the respective phases of the 240V supply. For the secondary side, connect the output terminals to the load requiring 480V, ensuring that the load is compatible with the transformer rating. Always follow local electrical codes and safety standards, and consider consulting a licensed electrician for installation.
Can you run 500mcm to feed 480 volt 400 amp service?
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
How do you power a 480V device from 120V home or kitchen outlet?
A: My advice is do not try it 120 v will require 480v /120 or 4 times the current. assuming 100% efficiency. a transformer can do it but there will be a loss of 20% . House wiring is 15 amps per circuit . So if your whatever unit needs more the 3 amps it just cannot be done. A PWM can also do this job more efficiently but then again the total power is in question.
What is the acceptable voltage higher than 480v for a 480v inverter?
The voltage range should be marked on the case but without that information a 5% increase can be assumed, so 504 v.
What does 277 vac mean?
That's 277 volts of alternating current. This is typically one phase of a 480v 3 phase system. Don't worry that 3 x 277 adds up to more than 480v. A 277v line is typically one phase of a 480v 3 phase system.
Wh would someone divide16.4kva by 480v?
Answer: To determine the amperage in a circuit. Notes: Power (in watts) = Volts * Amps 16.4 KVA = 480V * Amps 16400 / 480 = Amps ~34.2 = Amps
What is the nominal voltage of a 150 kW 480 v generator?
480V.
A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?
Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.
Can a 600V rated cable be use in 480V 3 Phase Ckt?
yes,
What size main breaker feeding 480v 75 kva transformer?
An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
Can a 1500KVA transformer feed a 1600A 480V service?
