How do you determine the equipment ground wire size for equipment?
It is an electrical code rule that is determined by the amount of current that a connected device draws. Depending on the amperage that the equipment will draw determines what the size of the wire needed to handle the fault current. The larger the amperage the larger the ground wire needed.
Can using larger wire sizes reduce amp draw?
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
Does an electrical receptacle draw power?
No the receptacle itself does not consume any power it is just a source of power. No amperage is used until the load is plugged in and turned on. Appliances plugged in with the switch in the off position draw no current. Devices that do not have an off- on switch will start drawing power as soon as they are plugged in. Once an appliance is switched on you are billed for the use of the electricity.
Does amperage and a voltage mean the same thing?
No, amperage and voltage are not the same. Voltage refers to the electrical potential difference between two points, measured in volts, while amperage (current) is the flow of electric charge, measured in amperes. They are both important components in understanding and working with electrical circuits.
What makes a marine battery's terminals hot?
Amperage draw, excessive amperage draw, and or dirty & loose connections. This should be checked out if the temperature is elevated when not cranking your engine.
How much amperage does a dishwasher draw?
Each electrical equipment draws a different amperage. Most residential dishwashers draw about six amps. There has to be a specification sticker on the inside of the door of the dishwasher ,which must such information stated on it. Commercial dishwashers could draw sixty amps and be using three phase power!!
How do you check amperage draw on electrical devices 12v DC automotive?
connect an ampmeter in series between the power source and the device ex. remove the power + wire and fit the ampmeter between the + wire and the device alternitively you can get clamp on ampmeters they are dearer but you can test amps with out removing any wires they just clamp on over the wire and give you an amp reading
How many watts does a compact fluorescent bulb draw?
Look for an amperage on the ballast. Multiply this amperage by the connected line voltage. This will give you the wattage of the unit.
Can you run a motor of greater amperage draw with a motor of less amperage draw?
It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.
What is loading rate?
The maximum amperage draw or load that the device or wire can safely carry.
What is circuit amperage?
Generally speaking an appliance (eg tv) is supplied with power so when it is off it has voltage supplied. After yo turn it on it starts to draw power called amperage the voltage doesn't get higheur but the amperage does Amperage is the load being drawn through a circiut
How many amps are in a C battery?
The amperage drawn from a C cell battery is governed by the load resistance. The lower the resistive load the higher the amperage draw from the battery.
