Do I have to wrap electrician's tape to cover all terminals on 480v outlet?

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 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.
480v 130kw how many amps?
Amps = Watts / Volts Amps = 130000 / 480 Amps = 270.83
How many kw in 480v?
The code book states that the motor will draw 1.8 amps. <<>> 1 amp
What size stranded 4 lead Soojw cord for 480v 60a load on a cord length of 10 feet?
SOOJW is limited to 300 volts and should not be used on 480 volts
Can you use a 30 amp disconnect switch for a 30 kva transformer?
im have a 30 kva transformer 3 phase 480v 80 amp panel 120v what size disconnect should I use
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.
How do you convert 380v 3 phase to 220v 3 phase?
Mathematically, just divide 480 by the square root of three. Electrically, 480V refers to the line-to-line value of a three phase system. For example, measure the voltage across A-phase and B-phase and you'll get 480V. 277V is the line-to-neutral value. Measure the voltage across A-phase and the neutral conductor and you should get 277V.
Can you run a 460v 60hz motor to a 480v supply?
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
