Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.

How do you change a heater from 120 volts 3a to 240 volts 1.5 a?
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
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.
How much current would a 5-kW heater draw with 230 volts?
The formula you are looking for is I = W/E, Amps = Watts/Volts. Amps = 5000/230 =21.7 amps. The wire size to run this heater would be a #10 copper conductor. The supply breaker would be a two pole 30 amp breaker.
What is the amp rating for a 2kw fan heater?
From a 120 Volt supply, the Amp rating is calculated as 2,000 Watts (which is 2kW) divided by 120 Volts = 16.7 Amps.
How many amps in 70 watts?
To answer this you have to know how many volts will be used. If you know the voltage then you can calculate the current by dividing voltage into wattage. For example; an electric heater rated at 700 watts when plugged into a 115 v outlet will draw 700/115 = 6.08 amps of current.
You have a 94 caprice classic if you supposed to get 220 volts 2 your heater element and you just getting 110 volts so whats the problem?
WHAT????? I hope this is just a comment that you have a caprice and has nothing to do with either 110 or 220 volts Heater element implies either a furnace or a water heater. Where are you checking the voltage? If at the outlet and you only have voltage on one side of the plug it's most likely a fuse or breaker. If there is 220 at the outlet but element is not heating it is the element. Under no circumstance get 110 or 220 anywhere near a 94 Caprice classic
If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
A hot-water heater has an 8-ohm element that operates at 240 V The power that's consumed by this water heater is?
VOLTS x (VOLTS/OHMS) = WATTS 240 X (240/8) = 7200 Watts = 7.2KWatts
Why are some heating elements rated for 230 volts and some for 240 volts and what would happen if they are interchanged?
Probably because years ago the voltage supply in most residential applications was 110/220V. It was increased to 120/240V to increase efficiency. If you use a heater element rated at 230V in a 240V application you will be "overvolting" it and will probably reduce the life of the element. If using an element rated at 240V in a 230V application you will be "undervolting" it and it will probably not get quite as warm as it is designed to.

If a 325 watt heater has a current of 6.0A what is the resistance?
Watts = Current x Volts with your resistive heat application. To figure out resistance you need to know voltage and current. Since you are drawing 6 amps then Volts = 325/6. This means that there is about 54 volts supplying the heater which seems like a very strange supply voltage. Since Volts = Current x Resistance the resistance = 325/36.
Is it safe to connect 380 volts 3 phase supply to 220 volts 3 phase supply?
No.

Can a 10-2 wire be connected to a 10-3 recepticle for a dryer?
No, the dryer needs 120 volts supplied by the neutral third wire, along with the 240 volts for the dryer element. One of the two 240 volt supply conductors is used with the neutral to supply 120 volts to the controls and the drum motor. That is why a three wire cable is needed.
