6 AWG is the nominal wire size in copper for 50 amps. 300 feet of 6 AWG has a resistance of .12 ohms. At 50 amps the voltage drop across .12 ohms would be about 6 volts. As a rule of thumb you want to keep voltage drop to no more than 10% of the supply voltage. So it you were using 120 volts you are okay at 300 ft with 6 AWG since the drop is only 5% of the supply. If you were at 240 volts it would be even better since the drop would be 2.5%.

Wire size for 500 Amp service?
For a 500 Amp service, the recommended wire size would typically be 4/0 AWG copper or 300 kcmil aluminum. However, it is always best to consult with a qualified electrician to ensure the correct wire size is used based on the specific installation requirements and local electrical codes.
What gauge wire hold 300 amps?
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.
What wire should you use in 300 amp three phase circuit breaker?
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.
What size wire is needed for 120VDC 1275 Amps?
To determine the wire size needed for 120VDC and 1275 Amps, you would use the formula: Wire size (AWG) = (Ampacity of wire)/(Current carrying capacity of wire). In this case, with 1275 Amps and 120VDC, the calculated wire size required is approximately 300 MCM (thousands of circular mils) which corresponds to a wire gauge of 250.
What size wire for 220 air conditioner heater?
The size of wire needed for a 220 volt air conditioner heater depends on the specific electrical requirements of the unit, including the voltage, amperage, and distance from the electrical panel. It is recommended to consult with a licensed electrician to determine the appropriate wire size to ensure safe and efficient operation of the equipment.
What size service head is needed to power 250 amp 415 volt installation?
If you use 250 or 300 MCM wire you will need a 2 1/2" weather head. If you use 300 MCM wire then you will need a 3" weather head.
What size wire should be used for a 200 amp service that is located 300 ft away?
For a 200 amp service located 300 ft away, a wire size of 2/0 AWG copper or 4/0 AWG aluminum is recommended to ensure proper electrical conductivity and safety.
Wire size for 500 Amp service?
For a 500 Amp service, the recommended wire size would typically be 4/0 AWG copper or 300 kcmil aluminum. However, it is always best to consult with a qualified electrician to ensure the correct wire size is used based on the specific installation requirements and local electrical codes.

What wire size is needed to ground a 300 amp service panel in USA?
Notes: 1. Where multiple sets of service-entrance conductors are used as permitted in Section 230-40, Exception No. 2, the equivalent size of the largest service-entrance conductor shall be determined by the largest sum of the areas of the corresponding conductors of each set. 2. Where there are no service-entrance conductors, the grounding electrode conductor size shall be determined by the equivalent size of the largest service-entrance conductor required for the load to be served. 1 This table also applies to the derived conductors of separately derived ac systems. 2 See installation restrictions in Section 250-64(a).
What size aluminum wire on 225 amp?
300 kcmil @ 75°
What size wire is needed for 120VDC 1275 Amps?
