How do you wire a relay to control a 220V circuit with two hot wires?
You need a double pole relay, that is a relay with 4 connection places. [screws, etc.]. Place your 2 hot wires on the screws marked line, makes no difference which wire on which screw. The 2 wires being energized by the relay action go on the load screws of the relay. Square D makes a good quiet relay. Also make sure you buy a relay large enough to carry the load. The amperage on the device the relay is to control will determine the relay size. See View Discussion for more information.
If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?
There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.
What does volts times amperage equal?
Voltage is equal to amperage time resistance. V=IR Therefore, I'd say voltage times amperage is equal to amperage squared times resistance. VI=IIR Really there's no point in multiplying the two. However, if you were to divide voltage by amperage, you would have the resistance of the circuit. V/I=R
What is the relation between amperage and capacitance?
The relation between amperage and capacitance is that amperage is equals to capacitance times the rate of voltage change over time. This voltage refers to instantaneous voltage.
Is 60 amp breaker good for 225 stick welder?
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
Where is starter relay escort on the Ford Escort?
The Escort doesn't have a starter relay. It has a solenoid on the starter that handles the heavy amperage.
What is a ignition relay?
The relay is a device that typically uses low amperage 12 vdc electrical (control voltage) to switch a much higher amperage circuit (load voltage). In the case of an ignition relay, the key/ignition switch is not capable of handling the high amperage requirements of the engine components electrical draw, so a relay is run in the circuit and controlled with the keyswitch. The relay has an electromagnet (control) and a switch (load) inside, and the electromagnet moves the switch when the control is energized. You do not ALWAYS have to have a burned fuse to have a bad relay, the contacts on the switch can burn, or the wire in the electromagnet can open, both resulting in a non-functioning relay.
What happens to the force generated by the circular coil of Relay if current direction is reversed?
As long as the amperage stays the same, the force in the relay stays the same regardless of direction of the current.
Is there a fuse for the fan in front of the motor?
Yes, if it is an electric fan. There is also a relay in the power distribution box under the hood. A relay is designed to carry higher amperage and voltage.
What is Overload Solid State relay?
a relay that detects the amperage the motor is drawing when the motor dwaws too much to drops out the coil voltage to shut down motor and prevent damage
Where is the dome light relay on a 1997 ford expedition?
Slot number #14 Amperage #15 amp Description; Interior lamps, delayed accessory relay, rear wiper relays
What is a relay in an 1995 Ford Escort?
I hope I am understanding your question correctly, but it sounds as though you are asking for a general explanation for what a relay is. All cars, not just an Escort, use relays. Relays are even found in your house. Your refrierator, washing machine, probably your television, and more have relays in them. In a nut shell, a relay is an electrically operated switch. It is a means to use low voltage or low amperage to control high voltage or high amperage. A relay has an electromagnet in it, that when it is energized, moves a contact inside to either make or break an electrical connection. One senerio in a car where this is needed is for the computer(low amperage componet) to operate a radiator cooling fan(high amperage componet). Let's say in our senerio, the engine is hot, and the computer decides to turn on the radiator fan. It supplies low ampere current to the coil windings in the cooling fan relay through two small pins on the relay. This moves the contact inside the relay which completes a circuit across two large pins at the relay to complete a high amperage circuit to the fan and switch the fan on. There are many other relays that perform a host of functions, like turning on the AC compressor, fuel pump, and even operate the starter.
What are the limitations of a solid state relay?
Stay with-in the amperage capability, the voltage capability, and use a heat sink to dissipate the heat build up.
What powers your 2000 fucus engine fans?
Usually there is a fan relay that is controlled by the engine computer. The relay coil is usually fed 12 volts and the return (ground) wire is grounded by the computer to energize the relay. The relay is there to handle the high amperage current that runs the cooling fans. Problems in this area can be caused by the relay being bad or the power source for the fans being absent.
Where is the relay fuse on an S reg Fiat Punto ELX?
No such thing as a relay fuse, you have a fuse in the wiring for each circuit, and some circuits also have a relay to reduce the amperage on a switch. What is not working on your car? then look up handbook supplied to find the fuse location in fuse box for the thing that doesnt work. if fuse ok then check relay but this needs more experienced person to do.

What is amperage?
Amperage is electric current of flow.
