You are watching: What size wire to run 300 feet
I"m walking to run 110v come the pier from the 200 Amp supply. It"s about a 300 ft run. If I want 15 amps in ~ the end, what dimension wire execute I must run ? additionally thinking about running conduit (PVC) rather of UF. If there is a table what online, I deserve to look that up. Simply don"t know what to find for ?
google "wire ampacity" or just check out the connect belowhttp://www.armstrongssupply.com/wire_chart.htm
What are you walking to it is in running out there?A voltage autumn calculator shows #6 to have actually 15 amps in ~ the finish of the run permitting a 3.31%voltage drop.
Will be to run LED pier and underwater lights. Want 15 Amps at 110 V.Found a graph that stated 10 AWG would go 550 feet, 12 would go 300.Sound ideal ?
Will be to run LED pier and also underwater lights. Desire 15 Amps at 110 V.Found a chart that claimed 10 AWG would certainly go 550 feet, 12 would go 300.Sound right ?
I don"t know the proper method to define it whereby you will understand. Right here is a list based upon 5% or less voltage drop with 15 amps at the end of the circuit. #12 =115"#10 =190"#8 =289"#6 =452"Problem is you space comparing a branch circuit to a feeder. When it comes to distance voltage is your friend. Your only option is 120V therefore you need to adapt through wire size.
here is the calculator ns use.http://www.southwire.com/support/voltage-drop-calculator.htmbased ~ above 120v (more likely, this is your source voltage)
300 feet, needing 15 amps, friend will require a #4 copper. Btw, don"t run uf. Conduit is the only means to go.
here is the calculator i use.http://www.southwire.com/support/voltage-drop-calculator.htmbased on 120v (more likely, this is your resource voltage)
300 feet, needing 15 amps, girlfriend will need a #4 copper. Btw, don"t operation uf. Conduit is the only means to go.
Carry friend must have actually put it in together a 3% drop, I obtained #4 as soon as I did that that means also.I download the southwire apps on mine phone so I can use that in the field.
I"ll go with lug on this one #4 will be a little an ext than you need (right now) however is is cheaper in the lengthy run.

From the Southwire calculator1 conductors per phase utilizing a #10 Copper conductor will limit the voltage drop to 7.87% or less when supplying 15.0 amps for 300 feet top top a 120 volt system. For design Information Only: 30.0 Amps Rated ampacity the selected conductor 1.1417 Ohms Resistance (Ohms per 1000 feet) 0.05 Ohms Reactance (Ohms per 1000 feet) 12.0 volts maximum allowable voltage drop at 10% 9.444. Yes, really voltage autumn loss at 7.87% because that the circuit 0.9 strength FactorGo v # 10 , you can live v the 8% voltage drop due to the fact that it is a light load.(check the lighting specs)You will have 110 volts at the end of the operation if you start out with 120 volts. #4 is 3 come 4 times together expensive as # 10 and the conduit will need to be bigger adding an ext cost. I carry out not see exactly how it will end up cheaper in the long run to download # 4 unless you room sure you will need an ext power. In the future.# 4 would probably be nice yet you would not gift doing it yourself if friend weren"t concerned around cost.
