Use 6 gauge
A 250 kcmil copper feeder cable would be appropriate for a 300 amp circuit breaker when stepping up from 220V to 380V. It is always recommended to consult with a qualified electrician or engineer to ensure the correct cable size for your specific application and wiring conditions.
300 watts or less.
You can use 5Rx 3.5 C x 240 sq.mm Al. Ar. XLPE cable ... or 6R x 3.5.C x 300 sq.mm AL. Ar. PVC cable - S.Ramamoorthie MEP - HEAD Bangalore
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
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.
300 feet Answer I believe it is many miles, when used in a teleplone circuit. They use a large battery voltage for voice over the line. 100 meters if used in an ethernet environment.
Get a longer cable. They can be up to 300 feet or so per cable.
The population of Optical Cable Corporation is 300.
The voltage insulation rating is not the factor that cables need to determine how much current that a wire can carry. Most home wiring is rated at 300 volts. A 3C #10 cable is rated for 30 amps. This is the cable that is usually used on dryer connections.
300 VAC stands for 300 volts AC, which is the measure of electrical potential difference in an alternating current (AC) circuit. It signifies the peak voltage that the circuit can reach.
You need to instal the same size and amp rating as you removed.You need to instal the same size and amp rating as you removed.
Depends on the size of the board.
