Got a few questions here not exactly grow room ones hopefully that will come later. need the main power first. Pulling power into my property and I think I have already made my first mistake. Heres the set up- I installed a pole with a 200 amp meter on it which the electrical company has energized via overhead service. I'm building my house with a 200 amp panel 250' from the pole. Pretty sure I blew it goin with the 200 amp service at the pole to start with probably should have requested a 400 amp. I'm at the point of trenching conduit from the pole to my house location. I was going to install 2" or 2 1/2" conduit for the run. I have no idea what size wire to pull for the 200 amp service at 250 feet. any input??????the conduit will go to the garage where I would like to have a disconnect with a few circuits, and a back up generator plug. from there I need to run a wire 60' to feed a 200 amp sub panel I installed in the house. I already bought the 200 amp switched subpanel, maybe I should install that in the garage and install a smaller sized sub in the house. any help you guys. Thanks
3/0 thwn copper.... go with the 2.5", its worth the $. pulling 3/0 through 2" 90's is no fun at all. and if you ever decide to upgrade your service, the larger pipe is already in...
the smart thing to do in your situation, since your already stuck with 200amps from the pole, would be to set whats called a 200 amp NEMA 3r
main panel distribution panel on the pole.
unless your house is like 4000 sq ft with a dozen people in it theres a very high likliehood that you will never actually use the full 200 amps. however having a 200 amp panel in the house
will allow you to have the proper number of circuits to fit all the breakers required for your kitchen, bedrooms, garage, etc etc. by setting a distribution panel at the pole, it will allow you to have
up to a total of 6 breakers in it.... you following me yet?
set the 200 amp distribution panel on the pole. feed your house panel from it with a 200 amp breaker and 3/0.
now here's where it gets ccol, and you get bailed out, albeit the cost is more... but it is a fix, a legal fix, and a really good one at that.
so now youve got a 200 amp panel on the pole...
with 5 slots left.... use the 5 remaining slots left in the distribution panel to feed a
seperate panel strictly for the grow.
not the cheapest option, but prolly the best option. as long as you dont exceed 120 amps on your grow equipment, youll be fine
