I want To operation 500 Ft Of wire From The dashboard At My house Underground To my Barn. Because that lights only.......whats The smallest Gauge WireI Can get Away with - likewise What size Breaker in ~ The Panel- full Light Wattage 450w - no other power required
According to my electric calc regime to acquire a 15 amp it is provided at the barn, and stay listed below the recomended 3% voltage drop, you will need to run 4awg copper minimum.

I want To operation 500 Ft Of wire From The dashboard At My home Underground To mine Barn. For lights only.......whats The smallest Gauge WireI Can acquire Away v - additionally What size Breaker in ~ The Panel- complete Light Wattage 450w - no various other power required
And running the lights on 12v method shipping 37a end 500"; no good.If the fill is just on intermittently you could do a battery arrangement and also just operation the short charging present over the 500" at short voltage.
# 8 AWG copper would be the the smallest you can go, and also it would be fed by a 15 amp breaker.What ns would carry out though is pull a multiwire branch circuit the end to the barn, that means two hots, a neutral and a ground, and also split the fill up evenly, and also then you might probably acquire away v running # 10 AWG out to the barn.
voltage dropvd=2KID/circular mils2xK (constant, 12.9 because that copper) xI(amps) xD(distance)so 450w. In ~ 120v is 3.75 amps. And the street is 500 feet. 2x12.9x3.75x500=48375now divide that by the dimension of the cable in one mils (this is whereby the codebook come in handy) because that #14 that is 4110, for #12 the 6530, #10 is 10380. Because that #14, you would get practically a 12v. Drop. Your only permitted 3% that 120 (3.6volts). #12 gets you 7.4 drop#10 it s okay you 4.6 drop. If i were you, and also your only running a couple of lights, and you desire to conserve money, usage the #12, 120 volts, 110 volts, that the exact same thing, for this reason why no 112.6? her lights will still work.
If i was walk to destruction a ditch 500 ft. Long (lot that work) I would certainly at least put a the very least a 10/3 wG UF cable in the hole! (#10 appears to be the many bang because that the buck)Put a very small subpanel in the barn with two 120 circuits. One for the lights and also at the very least one outlet.(GFIC on both)Never understand when friend will desire to plug other in!You won"t be doing any welding the end there but you will have actually plently that light.

I agree with napper. Trenching 500" is long method to go for together a little amount of capability. Walk bigger, you will certainly not be sorry. Her wallet will be significantly lighter though.

I would think about a solar charger, battery, inverter, and light. Must be cheaper 보다 the price of trenching. Last trench cost me $200, for 85".
Yes ns am a pirate, two century too lateThe cannons don"t thunder, there"s nothing come plunderI"m an over-forty victim that fate.

or a 2/3 hp petrol engine and also an alternator/generator. Probably some understanding engines have the right to put out this much power.At one or 2 kilobucks for the 15A job, because that the exact same or much less money you have the right to probably gain a pretty good setup that"s "off the grid."A square solar selection for this much consistent power would certainly be ~9" ~ above a side. If the lights space on 1/3rd of the time, ~5" ~ above a side.Speaking of shipping strength over a 500" distance and also not wanting come trench, i e-mailed the NFPA to ask if there is part voltage or current or power listed below which the NEC doesn"t care. Castle haven"t reply yet.A great guess is something much less than 30vrms, less than 42v peak, much less than 60vdc, and over 12vrms. Ns think workers in secret sewers, stand in water, usage 24v or 28v for the lighting.
jb fan, wish I might charge that much for a trench here. When i tell someone $1.00 every foot or $100.00 minimum lock act choose I asked for their first born child! Needless to say many of mine trenching is because that my very own needs.

Here in ~ the 208xx zip password area, a 36" walk-behind trencher is ~$170/day. I"d think 5 hours would do 500" on level ground, no stones, no roots.http://www.sunbeltrentals.com/equip...ource=google&gclid=CJvBtLHU6JQCFQiNHgodWlNaSg
No way would ns trench 500" simply to straight bury UF. That would most likely be 1.25" pvc minimum if I"m going come take the moment to operation power to a shed.Burying UF will certainly likely result in among these two callbacks:"I think I have a break in the wire reason I lost power to my shed.""I added a couple more things to my melted but now the breaker trips? What deserve to we perform to resolve it?"

How bout this one, i think we sized the voltage autumn wrong, my irradiate is an extremely very dim... :laughing::laughing::laughing:

Agreed. For much less than $175 in conduit, it would be much better to have actually the ability to upgrade later. Plus, the cost of THWN (plus the conduit) vs. UF, the full would more than likely come out the same.
