![]() Hopefully you will find things easier after going through the article. Then again for a stable power supply, choosing the best wire is important to avoid hazards. So, choosing the right wire efficiently will help you to reduce your cost. This article gives you a very brief and clear idea about the wires you will need and also how to determine the right wire for your task.Ĭhoosing the right wire for the power supply is very important for efficiency both in electric performance and economy. I hope you get a very clear idea about the size of the wires required to run a 500 feet service. For high voltages there are various voltage sensors found in the market. ![]() Learn how to test live wires if you think you are not clear about it yet. Before touching any wire, use a tester or voltage sensor. While working with electricity, the first priority is to take proper precautions. However, in most cases, it is common among home users and electricians to install a 6-gauge wire on a 60-amp breaker along with extra. 6-gauge wires are able to pull 55 amps, which means you should use 4-gauge wire for a 60-amp circuit. In America, there is a standard maintained for this case. Electrical wire manufacturing recommended charts recommend the maximum current that each gauge can handle. The size of the wire may increase with the increase in run. What Size Ground Wire For 200 Amp Service?įor a 120V system, you will need a 6 AWG copper wire or 4 AWG aluminum wire for a 200 Amp service. Doing so, the current will be divided into all of the parallel wires and you will find the voltage drop decreases. Just like a while earlier I said to use 4 parallel 4/0 AWG wires to carry the current. NM-B cable is primarily used in residential wiring as branch circuits for. And you can get the circular mills for a specific wire from the wire index.)Īs you can see that, the voltage drop for the chosen wire is 7.6% which is much more than 3%, you need a different cable or a different technique. Ampacity limited to that for 60 degree C conductors) as specified in the NEC 1. (Here, ‘K’ is a constant that depends on the material of the wire. If you want to determine the voltage drop for a copper wire that is going to carry 200 amps at a 500 feet distance by a 6/0 AWG wire then, Once you select the wire according to the current capacity, then you need to calculate the voltage drop. You can use the current capacity chart for AWG wires. To determine the suitable wire you first need to see the maximum current capacity of the wire that matches your criteria. How To Determine The Suitable Wire And Calculate Voltage Drop? Keeping the voltage drop as low as possible is a must for high loads. But the voltage drop will be a bit higher than 3%. You can alternatively use two 6/0 AWG cable in parallel. To be exact you will need 4 parallel wires to complete the job keeping the voltage drop within 3%. To run a 500 feet 200 amp you will need a number of 4/0 AWG wires in parallel. But you can use a 2 AWG copper wire if you are ready for a voltage drop slightly higher than 3%. If you are going to use a 20 amp capacity feeder, you can use a 1 AWG copper wire at a voltage drop of below 3%. What Size Wire To Run 500 Feet?įor a 120V run of 500 feet length you may use a variety of gauge wires depending on the current capacity. Like, where you need a 2 AWG copper wire, 4AWG aluminum wire can serve the same requirement. While replacing one with the other, aluminum needs to be thicker than the copper wire. Normally there are two types of elements used in the wires- copper and aluminum. These things determine which wire you need for the job. ![]()
