To carry 300 amps of current, you would need a very large wire size, likely in the range of 3/0 or 4/0 gauge wire. It's important to consult with an electrician to ensure the wire size meets building codes and safety standards for such high amperage.
A zero gauge wire can typically handle up to 300 amps of current. However, the exact capacity may vary depending on the specific wire material and insulation used in the wire. It is important to consult the manufacturer's specifications for the wire you are using to determine the exact ampacity.
The ampacity of a # 10 copper wire with an insulation factor of 90 degrees C is 30 amps. All wire voltage ratings usually drop into two categories 300 volts and 600 volts. Home wiring drops into the 300 volt range and commercial, industrial, drops into the 600 volt range.
I wouldn't, always safer to go heaver gauge. I recommend 8 gauge if you are going to be running any length of wire. Fire is never fun I believe the above answer assumes the question was meant to read, "30 amp 220 volt dryer." 12 gauge wire WILL NOT carry 30 amps safely. You need to run #10 copper minimum. It is never a bad idea to upsize, such as the recommended #8, but it is not necessary if 30 amps is what you need.
Two thoughts here, one the fixture should be rated at the maximum wattage allowed for the socket the bulb screws into. A label should state "maximum wattage allowed". To do a calculation Watts = Amps x Volts. Amps = Watts/Volts. 5 x 60 watts = 300 watts. 300/120 = 2.5 amps. The electrical code only rates down to #14 wire which is rated at 15 amps. From here you have to make the decision.
No, a 12-gauge wire is typically rated for a 20 amp circuit. To safely handle a 25 amp breaker, you would need to use a 10-gauge wire. It's important to match the wire gauge to the amperage rating of the breaker to prevent overheating and potential fire hazards.
A zero gauge wire can typically handle up to 300 amps of current. However, the exact capacity may vary depending on the specific wire material and insulation used in the wire. It is important to consult the manufacturer's specifications for the wire you are using to determine the exact ampacity.
About 300 lbs. Maybe, but it depends on the gauge of the wire and the hold of the anchors and weight of the wire itself... more information would help for a better answer.

I would use #12. THHN #12 is rated for 30 amps. <<>> The minimum size wire that you can use, to save overhead costs, is #14 wire which is rated at 15 amps. Home wiring cable has a rating of 300 volts. Also the above answer is wrong, #12 is only rated at 20 amps. If you have doubts about an answer check out the answerer's bio by clicking on their name.
For a 300 amp three phase circuit breaker, you should use wire that is rated for at least 300 amps. The wire gauge needed will depend on the material (copper or aluminum) and the installation method (conduit or cable), so it's recommended to consult with the National Electrical Code (NEC) or a qualified electrician for the specific wire size required. Using the correct wire size is crucial to ensure safety and prevent overheating.
# 4 gauge THHN or THHW is rated for 95 amps and would normally be the correct wire size. However, at 300 ft. from the source, you definetely will have a substantial voltage drop. Therefore, you need to up the conductor size to # 3 gauge.
There is no such thing as a watt amp. To determine wire size you need to know the current. Watts = Current x Voltage, so if you know the applied voltage to the load that consumes 300 watts you can get the answer. If we assume 120 volts as standard home voltage then current is 25 amps. If you had 240 volts it would be 12.5 amps. In general 14 AWG is 15 Amps 12 AWG is 20 Amps 10 AWG is 30 Amps
The first thing we have to do is clarify between the two items. 120 volt wire rating is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. The ability of a wire to carry current (amps) is related to the size of the wire. Now, watts is the product of amps x volts. To answer this question, assuming the supply voltage is 110 volts, an amperage needs to be stated as per the formula above.
