Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
What is the performance like of an electric stove rated for 240V that is connected to a 208V supply?
Not good. The heating elements expect 240 volts. Possible, alternate burners elements can be purchased. (Read contact manufacturer.) Otherwise a buck/boost transformer can increase the voltage to 240 volts and the stove will run fine. Essentialy, 208 volts has 86 % of the energy of 240 volts.
How many wires do you need for a 208 v circuit?
208 v is a three-phase supply voltage used in North America, carried on a 4-wire system. The voltage between one of the three live wires and the neutral wire is 120 v and a single-phase supply can be taken by using one live and the neutral. If in doubt about the connection consult an electrician.
What is the breaker size for a 10 KVA electric heater?
What size breakers are needed for a 30kva transformer 208 volt feed 600 volt out put
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
45000 / 208 /sqrt(3) = 125A per phase this is probably called a boiler unless it has a 2000Gallon tank
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
How do you convert 120VAC 60Hz to 208 230 1 Phase?
you need a step up transformer
How do you get 208 on a single wire?
You don't. Every circuit needs a return wire back to the source.
Can you convert 240V 3 phase to 208V 3 phase?
Yes, with an auto transformer. It is a transformer with multiple taps on the winding. Connect the 208 volts across the common tap and 208 volt tap. Then connect the load across the common tap and the 240 volt tap.208 VAC usually comes from one floating side of a Delta 3 phase transformer.240 VAC usually comes from a grounded center tapped transformer.Using an autotransformer would be very hazardous and violate code. Probably tripping the 208 VAC breakers.The only way to do it correctly would be with a transformer with a 208 VAC floating primary and a 240 VAC grounded center tapped secondary.
What is the ratio of primary to secondary turns of a transformer if internal resistance is 12.8 ohms and load resistance is 8 ohms?
600 by 208
What size ground wire needed for 75 amps at 208 volts?
#8 copper
How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
What is the wire size for 208 volt?
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
Which bell telephone company modem series supports four-wire synchronous transmission?
208
Why is a three phase four wire distribution system used?
A three phase four wire system allows for two voltages from a single three phase transformer. The transformer configuration is a wye or star connection. It is used in commercial and industrial applications. Apartment buildings are now starting to use a three phase four wire service distribution system. Some wye connection voltages are 120/208 volts, 480/277, and 600/347. The lower voltage is derived from the sq root of 3 divided into the three phase voltage.
What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
Transformer 208 volt primary and 480 volt secondary three phase 75 kva what size fuses on primar and secondary?
200 and 100
