You are watching: What size wire for 200 amp service 500 ft away


Need to run from meter come high usage house and also shop 600 feet away. I have never excellent a run this long. Wonder if i go to transformers (new come me) or get into the 750 Al or 400 CU. Everyone have any experience in these long rural runs? If I perform go v the 750 AL or 400 CU just how do i fit it into the dashboard lugs?
usually in alberta twin runs of oversized cable based on amps over distance tables or calulations, sometimes just have power agency put in a second service, therefore they will have actually one transformer pole at house and also a second transformer pole in ~ the shop. Each with their own organization drop.You can go to 480 or 600 in step up action down, but that will be really expensive and the owner will probably start wondering what is walk on through all the gray enclosures.
That"s what ns thought. However the wires won"t to the right in the lugs. I guess I might drop them down from Aluminum to smaller sized copper that would fit ~ above both ends. Never done that before. Probably an high-quality part.
usually friend would put a splitter ~ above the end of the twin circuit and then nipple come a short length of solitary cable taps.

2 conductor(s) every phase utilizing a 600 kcmil Aluminum conductor will certainly limit the voltage drop to 2.70% or much less when offering 200.0 amps for 600 feet top top a 240 volt 1 step system.

400 MCM CU. Is the method I"d roll.If times gain tuff they have the right to dig the up and make a couple of bucks:whistling2:A couple years ago I go a residence in Trinidad, meter was 500ft native house, we offered direct funeral 350mcm CU and also i think 4/0 Cu because that the neutral.. The just pain to be the lugs. The owner didnt want the trannys ~ above the property and didnt like the idea that regardless of need they were still suck a little bit that juice. I think it was about 12-14k in wire. An excellent luck:thumbsup:

You don"t actually have actually 200 amps fill do you? do a business calc.I would placed a Midwest tapbox on every end and run parallel 4/0 quads. Then operation 4/0 into the panel.

The customer plans on offering a huge home and a high use job-related shop. Desires as much power together possible. I know they won"t obtain up come 200 amps. We deserve to save $ through aluminum yet my issue is figuring out exactly how to to the right the big diameter wires right into the lugs on the panels. I"m reasoning they should make some sort of one attachment because that this situation. I"ll call Cutler Hammer. Trinidad Humboldt?

I would simply hit a splice have the right to ahead that the meter and reduce down to a single standard size set of conductors.

I would certainly of had actually parallel set of conductors heat side of (320)A. Meter pan and also single collection going to feed panel..No require for a splice can..

We are both wrong, the meter is in ~ the start, therefore if the power firm was fine v a 320 socket for a 200 amp company you could do one collection in two sets out.

I looked in ~ a project a couple of weeks ago.. Around (560) feet because that a 200a service..Plan was to parallel indigenous existing transformer come MP situated at brand-new building on 4X4 stand and run single set to new building as soon as walls are up.. I have actually not met through POCO however to operation this previous them.. For this reason this conversation is fine timed.. :thumbsup:

ResultsBuilding inspector desires at least 500 MCM Aluminum. The idea of circulation blocks seemed great but needs separate boxes with much more labor connecting coduit etc. I choose the polaris connectors since they have the right to go in meter box and main panel on both sides through minimal labor. For this reason I will certainly run 500 or 750 MCM aluminum and also reduce down to max size copper that will fit in the lugs on both ends using polaris connectors. Thanks for the help.
It sure as hell wasnt on mine dime! Toto, yes Trinidad in Humboldt County. Not Trinidad/Tobago:laughing:
