What would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
Why would you get 65volt on 120volt output on a 480volt to 120volt transformer?
Your neutral May not be grounded good
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.
What element is in the heating element for toasters?
That would most likely be a nickel and chrome alloy. Light bulbs use tungsten.
What would cause a 1996 Mitsubishi Galant to have no heat?
heating element stopped working
Why does a hairdryer on the 240 volt setting work in the US and does this mean the switch to change the voltage is faulty and it's not really operating on 240 volts?
Hair dryers usually have a HIGH and a LOW setting. The HIGH heating element is about 8 ohms. The LOW heating element is about 32 ohms. voltage (squared) / resistance = power (watts) 120*120 / 8 = 1800 watts ( HIGH ) 120*120 / 32 = 450 watts ( LOW ) When the voltage switch is set to 240 volts, ALL it does is limit the HIGH/LOW switch to the LOW setting. 240*240 / 32 = 1800 watts ( LOW ) 240*240 / 8 = 7200 watts ( HIGH ) (the heating element would burn out)
What will happen if the heating element is near at the top of the kettle?
In that case, it would be less efficient. Hot water rises to the top, mixing the water (if the heating element is at the bottom). When it is at the top, the water won't mix as well, and more heat would be wasted.
Why Side mirror not heating in VW passat?
Is it just one mirror? I would look at a possible broken wire or heating element on the mirror. If it is both, I would look at a possible bad switch since it affects both mirrors.
What would full load amps be on a 480volt 3 phase 90 kw electric heater be pulling 36 amps per leg?
46 amps
What is the amp draw of an open hot water heater element?
Check the appliance's specifications on the strip, tag or plate that is usually fixed either on the back or somewhere on the frame. On there you will find its required operating voltage and wattage that it draws.If your home has 240 volt line voltage just divide the watts by the volts for the answer.Example: a 2400 watt water heater for a 240 volt line using the formula watts / volts = amps would give you 10 amps. For a 120 volt appliance it would be 20 amps.
How do you top-broil?
You would top-broil in a stoves broiling drawer if it has a flame or electric heating unit above it. You can also use an electric toaster/oven/broiler with a broil setting for an overhead heating element.
What would cause a circuit breaker heating element to trip off?
There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.
