Is it safe to use 3 heavy duty extension cords together?
Yes, the use of an extension cord is safe, as they have been underwriter laboratory tested. An extension cord is meant to be used as a means of bringing power to a portable device for a temporary period of time. They should only to be used as a temporary fix until a permanent installation can be installed.
How do you prevent a wire from getting hot?
An overheated wire is an indication that you've put too much current through the circuit. The device you're driving is pulling more current than the wire is capable of safely carrying. Either use a larger wire or use a device that pulls less current. There are no other choices.
What appliance uses the larger current a toaster or a table lamp?
The toaster wins over a table lamp. To accurately measure this compare the wattage of each device.
Can 12V 1A adapter be used for 12V 2A device?
no, it may damage the appliance.1Can_12V_2A_adapter_be_used_for_12V_1A_device, 2a adapter cannot be used for 12v, 1a device if the so mentioned parameters are input parameters of the device.Yes, a 12 volt 2 amp adapter has more that enough capacity to operate a 12 volt 1 amp device. In fact the adapter can operate devices up to a limit of 12 volts 2 amps. A device larger than 2 amps connected will tend to heat the adapter up and eventually cause it to fail.
What is the best size wire for a welder extension cord?
25 percent larger wire for 50 feet.
What does the horn relay do in a 1963 Chevy 2?
A relay is a device that uses a small control current to switch a larger current. So the horn button (small current) turns on the relay which in turn energizes the horn (heavy current device).
How much larger is the starting current than the full-load operating?
I am pretty sure that that varies, depending on the specific device.
How many volts is in a size c battery?
Size C batteries have about 1.5V, similar to a AA, AAA, D, etc. The difference lies in the amount of current the device draws. The larger the battery, the more current available. So in effect, the larger the battery, the more mAh (milli-amp-hours) available to the device.

What is amplifier and types of amplifiers?
Amplifiers are electronic device that responds to a small input signal (voltage, current, or power) and delivers a larger output signal.
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.
What appliance uses the larger current a toaster or a table lamp?
The toaster wins over a table lamp. To accurately measure this compare the wattage of each device.
Will a 5 amp device work with a .5 amp power cable?
Yes, the larger cable can carry more load (current) than the other cable.
Can you replace 5A fuse with a 15A fuse for hot water cylinder?
No. The device is fused at 5 A for a reason. A larger fuse will allow more current to flow than the device can handle, possibly causing a fire or shock hazard.
Can an extension cord be to large for any appliance?
If you are talking about the gauge of the wires, then no. Larger guage wires( numerically lower) will pass current required for the appliance with lower losses, so it is better in that reguard Less resistance= less waste( in the form of heat). If you are talking about LENGTH, then yes. The longer the cord, the more losses that occur. Voltage lowers, so current goes up. If the extension cord can't pass the required current, then voltage remains depressed, and you end up with an appliance and extension cord that are running hotter, and less efficient. Worst case; fire.
