What gauge wire needed for 20 amp for over 60 foot run?
12 AWG. You can run several hundred feet.
What size wire for 100 feet 20 amp circuit to run pond fountain?
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
How many amps can a 8 gauge wire run coming from the ditribution panel to the sub panel 25 feet away?
A #8 copper wire with an insulation factor of 75 or 90 degrees C is rated at 45 amps.
What size wire IS needED FPR A 30 AMP OUTLET BOX?
It depends upon the length of the circuit, but for 50 feet or less a 10 gauge wire should be fine. A short length (15 feet), you could use 12 gauge. If you double the length to 100 feet, you should use 8 gauge. A rule of thumb is to drop down a gauge for every length that is doubled. There are wire size charts available on the internet. Some can be conservative such as recommending #8 for 50 ft or less at 30 amps. It is better to be conservative than to run too much amperage on a smaller wire that can cause a fire. As a general rule, 12ga wire can be used in house circuits for 20amps or less. 16ga wire can be used for 15 amps or less such as lighting circuits. That is considering lengths of less than 100 feet.
What gauge wire is used to run smoke detectors?
14-3 Is the standard wire use for residental smoke detectors.
