You don't. You hire a qualified electrician who doesn't need to read this page for the answer.
That said, if you are merely curious as to the methods:
"480" Volt will be 3-phase with either Delta wiring (480 phase-to-phase, NO neutral), or Wye wiring (480 phase-to-phase, and 277 phase-to-neutral).
You can use this directly, to run three phase equipment from all three phases, to run equipment at 480 from just two phases (being careful to keep loads balanced), or to run lighting circuits from the 277-to-neutral (being careful to size the neutral conductor carefully).
You can also step it down to "208", which will be 208 phase to phase and 120 phase to neutral -- "standard" line voltage.
But seriously, if you need to ask the question, you SHOULD NOT be touching 480 switchgear and wiring, for the safety of both yourself and others.
What else can I help you with?
Can you tap off a 3 phase 277volt ac light fixture to power a single phase 120 volt ac recptacle?
NO! The voltages available in the 3-phase system are 480 (if you wire phase to phase) and 277 (if you wire phase to neutral) Don't try it!
Can you get 120 volts from a 480 volts 3 phase Y generator?
NO, the 480 Volts Y -- is 4 wire system, with three wires which are hot legs @ 480 volts between each three hot legs. A mid tap is a neutral leg (ground) the white wire. Which gives 277 volts between it and any of the three hot legs. so a 4wire 480 volt Y system. Gives 480 /277 volts.
Can you wire two 6 volt batteries together maintaining 6 volts but wire a separate plug off the batteries in such a way as to have a single isolated 12 volt plug?
Yes, series the two batteries to produce 12 volts. Tap off of the two end terminals for the 12 volts. Tap off of the series jumper for the 6 volts of one of the batteries. The two 6 volt batteries can not be paralleled in this connection as they will short out.
Can you replace a 5 volt power supply with a 10 volt power supply?
If the power supply has a 5 volt tap on the secondary side of the transformer, yes. If there is no tap and the secondary side of the power supply is only 10 volts then no, you can not substitute the higher voltage unit.
How can a step down transformer which is transforming 450 volt in the last tap be changed to 415 volt?
The instruction for changing the taps on a transformer can be found on the transformers nameplate. These taps will be on the primary side of the transformer. Each tap position will state what the voltage will be on the output when the individual tap is selected.
Why there is a need to disconnect transformer while using off-load tap changer?
Changing off-load tap changers requires opening up the transformer, draining (at least some) oil, and manually changing electrical connections. None of these things can be done while the transformer is hot.
How do you take off a flywheel out of a 1991 gmc g2500 5.7 ltr vandura?
disconnect the trans slide back - disconnect torque converter clear flywheel get two 5/8 socket wrenchs and use one to loosen and one to tighten do that till all of them is loose and then tap at the bottom and turn as you tap to remove the flywheel
Can a hps light fixture be plugged in to a regular outlet?
If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
Will most transformers that go from 480 volts to 277 volts go on down to 240 volts?
Most transformers designed to step down from 480 volts to 277 volts typically can be configured to also provide a 240-volt output. However, this depends on the transformer's design and tap settings. It's essential to consult the transformer's specifications or a qualified electrician to confirm its capabilities for specific voltage outputs.
Why it is necessary to disconnect the load when change the tap?
when the load is connected to draws some current. while changing the tap of the transformer the tappings related to the winding is changed , so the load current affects the transformer. hence while changing the tap it should be noted thatAnswerThere are two types of tap-changing mechanism -'off-load' and 'on-load'. Off-load tap changers physically disconnect the winding when changing from one tap setting to the next. Accordingly, the circuit is temporarily broken, and dangerous arcing will take place if the transformer is energised. Therefore off-load tap changers require that the transformer is disconnected while the mechanism is operated.On the other hand, 'on-load' tap changers use a mechanism which incorporates a 'make before break' contact arrangement, ensuring that no break is made in the circuit as the mechanism moves from one tap setting to the next, enabling it to operate with the transformer energised and supplying load. On-load tap changers are usually automatically operated, although this feature can be overridden and operated manually.
Tap switched12v power in your car?
Please be aware that using 12 volt power off the ignition switch must be done carefully as the Ignition switch only has so much load carrying capacity.
What happens if you wire 120 volts to the 277 volt tap on a multi tap ballast?
Operating at half the required voltage, the lamp will not operate at full capacity if it comes on at all.
