Can 120 240 volt and 277 480 volt conductors be installed in the same conduit or box?

NO! The National Electric Code requires a partitioned box when high and low voltages share the same box. Always avoid installing different voltages in the same box, it's a bad idea.

A 277 volt switch has a different screw to box configuration that a 120 volt switch. This is also true for 347 volt switches. The switch is configured this way so that 120 volt switches can not be used on the wrong voltage inadvertently
According to the 2008 NEC 300.3 C 1 says yes as long as all the conductors in the wiring enclosure have at least an equal insulation rating as that of the maximum circuit voltage applied.

∙ 13y agoYes, you can run different system voltages in the same conduit and boxes. The conductors must be rated for the highest voltage present and used on all circuits.

Yes, a 220 volt appliance can be installed in your home.
What sorts of questions are on the Journeyman Electrician License Exam?
What gauge of wire is required to carry a certain amperage X number of feet? How do you break out a 120 volt circut from a 3 phase line? When installing a load center, how should the ground be installed? What locations require Ground Fault Interrupters to be installed? How should a 240 volt dryer plug be wired? What is the minimum size conduit that 3 0 gauge wires can be pulled in? Can 12 guage Romex be used to wire a water heater?
How to Replace 120 volt pool light with a 12 volt pool light?
You may not be able to do that. The 12V system will have a larger cord and may not pass thru the exhisting conduit. Call an electricial who knows swimming pool electrical codes.
What size wire for neutral in a 240v 30 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.
Can a 277 unit heater be supplied with 240 volts?
Absolutely not!! 277 volts is developed from a 480 volt power supply employing 1 conductor and a neutral. 240 volt power comprises two hot conductors and NO neutral.
Can you run 110 and 220 volt circuits in the same conduit?
Yes, 120 and 240 volts can be run in the same conduit.
Can 480 volt electric be run in emt conduit?
Yes 480 volt electric wiring can be run in emt conduit.
Can you install more than 8 conductors of 480 volt in a 2conduit?
That depends on the size of the conductor and the type, which is defined by its insulation. With many common large feeder conductors such as THHW, the largest conductor which you can run 8 of is # 2 gauge. Whereas common small branch circuit conductors such as # 12 THHN, you can run 138 ea. through a 2 " conduit. For the complete list, look at the chart titled "Maximum number of conductors in electrical metallic tubing" (EMT) in the National Electrical Code.
Will a120 volt meter blow up if installed in a 480 volt installation?
Yes
Install to 220 volt appliance at home?
Yes, a 220 volt appliance can be installed in your home.
What type of conduit is used for 480 volt 3-wire?
Conduit is just a medium to get the wires from one place to another. There is no voltage restrictions in low voltage wiring (750 volts or less). When it comes to conduit fill, electricians are governed by the electrical code conduit fill tables. The conduit is sized to accommodate the conductor size for a specific load.
How do you size the neutral in a 240 volt system?
On a 120/240 volt distribution the neutral is sized along with the supply conductors. The sizing is based on the amperage of the service distribution.

Can the wrong size car battery damage the alternator?
No, not unless you installed a 6 volt battery instead of a 12 volt battery.
Mega test value for 240 volt marine system?
There should be at least 2 meg-ohms between the current carrying conductors and between current carrying conductors and ground.
How to Replace 120 volt pool light with a 12 volt pool light?
You may not be able to do that. The 12V system will have a larger cord and may not pass thru the exhisting conduit. Call an electricial who knows swimming pool electrical codes.
How do you convert a 125 volt to a 120 volt receptacle?
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
