Yes, if properly wired a 20 amp circuit is a great circuit for an 18 amp appliance.
Properly wired means you've used 12 gauge wire or larger and the circuit is protected by a 20 amp breaker or fuse and all connections are secure.

Yes, you can use an 18 amp appliance on a 20 amp circuit. As long as the circuit has a higher amp rating than the appliance, it is safe to use. Just ensure that the appliance's amp rating does not exceed the circuit's capacity to prevent overloading and potential hazards.

Can you have an 18 amp appliance on a 20 amp circuit?
Yes, you can have an 18 amp appliance on a 20 amp circuit. It is important to leave some room for safety margin, and a 20 amp circuit should be able to handle the 18 amp load without any issues. Make sure the wiring and circuit breaker are correctly rated for the load.
Can you use both 15 amp and 20 outlets on the same circuit?
It is generally not recommended to mix 15 amp and 20 amp outlets on the same circuit because it can create a safety hazard. If the circuit is protected by a 15 amp breaker, using a 20 amp outlet could lead to overheating and potentially cause a fire. It's best to match the outlet amperage with the circuit breaker amperage for safety and code compliance.
Can you use 20 Amp with 250 Volt Fuse instead of 18 Amp with 250 Volts fuse in microwave?
No, it is important to use the correct fuse amperage rating for your microwave. Using a higher amperage fuse than recommended can lead to safety hazards, such as overheating and potential fires. Stick to the manufacturer's specified fuse rating for your appliance.
How much current does it take to trip a 30 amp automotive circuit breaker?
In a typical US automobile, a 30 amp fuse will sustain a constant load of 360 watts. Fuses and circuit breakers perform on an "I squared t" rule. For example, a 30 amp fuse will not blow on 31 amps for a very long time. A 20 amp breaker can take anywhere from 10 minutes to two hours to trip on 25 amps. We simply dumb it down so that laymen and technicians need not make mistakes. Power on seven 100 watt light bulbs simultaneously. That means a circuit suddenly provides 50 amps. 50 amps does not trip a 15 amp or 20 amp breaker, again, due to the "I squared t" rule. A 50 amps load only exists for tens of milliseconds. Not long enough. A 30 amp continuous appliance will not trip a 30 amp breaker. But a safety margin means limiting 30 amp appliances to 26 amps or less. Meanwhile, an 18 gauge lamp cord wire typically rated for 10 amps will actually conduct up to 50 amps continuously. Again, that wire is oversized for other safety reasons. And to keep it simple. These concepts apply to fuses vehicles and structures.
Can you run a 115 volt 15 amp air conditioning unit on a 110 outlet?
It is generally not recommended to run a 15 amp air conditioning unit on a 110 volt outlet designed for lower power devices. The unit may not function efficiently or may overload the circuit, causing safety hazards. It is best to use the outlet that meets the voltage and amperage requirements specified by the air conditioning unit.

Can I use a 12v 18 amp battery and connect to a circuit that asks for 12v Static current 6mA Can I use resistors to lower the amps on the 12v 18amp battery or can I just connect it up?
Just connect the circuit. It will only draw the amps it needs to operate. It is just like connecting a 100 watt light bulb that draws way less than 1 amp, to a 20 amp household circuit.
If a 12 volt 18 amp hour battery is installed in a circuit with a continuous 1 amp current draw on the battery what would happen?
would discharge in 18 hours
Will a 120 volt circuit carrying a 2200 watt load blow a 15 amp fuse?
It will draw over 18 amps and will blow a 15 amp fuse.

What Wire kit do you use for a 180 watt amp?
18 gauge
Can you use a 230v saw on a 40amp circuit?
Possibly, most 230 volt saws draw about 16-18 amps on each line. There will be a spec plate on or by the motor which has the amp draw marked. CHECK this first.
What will be the amps of a 12v 2amp circuit if there is a 12ohm resistor on it?
The formula you are looking for is I = E/R. Amps = Volts/Resistance. If you say it is normally a 2 Amp circuit, it normally draws 2 amps. Therefore the original resistance offered to the 12v battery is 2/12 = 6 Ohms. If you then connect a 12 Ohm resistor in series, they are added, so R = 18 Ohms. Now if you put 12v across this circuit it will draw 12/18 = 0.66 Amps. Or If you just put a 12 Ohm resistor across the 12v supply it will draw 1 Amp. If the circuit is protected by a 2 Amp fuse, it will not blow, but the resistor will get hot.

Can you splice 18 gauge wire and 12 gauge?
Try it see what happens... >:l Can you splice them? Yes. Should you splice them? No. It really all depends on what your over current protection is. If your #12 wire is on a 20 amp breaker, your #18 wire can melt and cause a fire without tripping the breaker. I do not know what is the amp rating of 18 gauge wire. -- Sparkfighter
