No. Disconnect switch ratings represent the maximum voltage that can be properly interrupted by the switch. As the blade opens, an arc will occur across the opening blades, and the switch is designed break the arc at a particular distance, or air gap. Higher voltage can retain the arc for a longer distance, and so the arc may not be properly interrupted. At 480 volts, this can result in a dangerous electrical hazard known as "arc flash", which could result in burns or injury.

Can you use a 30 amp disconnect switch for a 30 kva transformer?
Yes, a 30 amp disconnect switch can be used for a 30 kVA transformer. The 30 amp rating refers to the switch's capacity to safely handle 30 amps of current, which is sufficient for a 30 kVA transformer's load. Just make sure to follow the manufacturer's guidelines and electrical codes when selecting and installing the disconnect switch.
Can you install a 3-way switch on a 240V circuit and if so how is it wired?
I believe you'd have to use a standard set of three way switches and a contactor. Tie the 120 volt coil to the three way switches and the 220 volt contactor to the load.Unless your talking about a 277 volt load, then you can use 277 volt switches.Use a relayYou're probably better off trying to wire a separate 3-way switch circuit (at 110 or even 24 vAC) to control a heavy-duty relay that operates the 220-volt device.
How do you install a 240 volt light switch?
I'm guessing you want to know what a 240v switch is? If you look at a 120v single pole switch, you will see two brass screws on one side. This type of switch is designed to interrupt current flow in one conductor. A 240v switch is really a double pole switch. It has 4 screws and is capable (and required) of interrupting current flow in two conductors simultaneously. This is an NEC requirement. It allows a local means of disconnect instead of having to go back to the breaker, and a multiwire disconnect is required to disconnect all ungrounded (hot) conductors at the same time. That way one 120v leg cannot be shut off while the other is on. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
How many output amps is a 600kva generator at 240v?
To calculate the output amps of a 600kVA generator at 240V, you would use the formula Amps = kVA / Volts. In this case, it would be 600kVA / 240V = 2500 amps.
What kind of fuse need to use for 240V outlet?
For a 240V outlet, you should use a fuse that is rated for 240V. The fuse's amperage rating should match the amp rating of the circuit and be appropriate for the connected devices. It's important to use the correct type and rating of fuse to protect the circuit from overloading and electrical hazards.
Can you use a 240V disconnect switch for a 120V AC?
Yes and you will have a spare terminal for future use

Can you use a 240 volt 3 phase disconnect with 460 volt?
It's possible, but not at all economic. Usually the 240V (sure it's not 277?) has been stepped down from 480V service already. Sounds like this is a commercial application. 480 is rare in residential, but quite common in commercial. If you need 480, you'll need to get ahead of the step down transformer.AnswerYou cannot obtain a three-phase supply from a single-phase supply.

Can you use a We Mo light switch on 240v?
The conscience is no. There is a work about by using an intermediary relay coil rated at 120 volts to switch the 240 volt feeder line.
Can a 600V rated cable be use in 480V 3 Phase Ckt?
yes,
What is used on a single phase induction motor to disconnect the start winding after the motor starts?
A centrifugal switch, once the motor reaches near run speed, centrifugal force causes a set of contacts to open and disconnect the start capacitors. Some larger motors use a contactor which is disconnected by the centrifugal switch.
What will result if a smart switch is disconnected at the connector?
When troubleshooting, if you disconnect a smart switch, a code will be logged immediately. Always use the system self-diagnosis to locate problems.

What type of switch should I use to switch between 2 100 hp air compressors fed off a 200 amp disconnect.?
To answer this question the voltage of the system must be stated. You may need to use a splitter after the main disconnect and then two fused disconnects for each individual motor feed.
How do you use a 120Vpower supply on 240V?
No, you cannot.
What are the specifications and features of the 200 amp outdoor disconnect switch?
The 200 amp outdoor disconnect switch is designed for outdoor use and has a current rating of 200 amps. It is typically used to disconnect power from a building or equipment. Features may include a weatherproof enclosure, a handle for manual operation, and a lockable design for safety.
