	Subject - 200a Sub Panel in Garage poland I had just built a Garage and want to hook up a 200a sub panel, for welder,exhaust and what ever might come up. later(next year)I want to build a house next to it with another 200a main panel. I'am not sure of all the codes in Residental,I'am an Industrial electrician. Could you help me out or give me some ideals. Thank you frenchelectrician ok ,, i will like to clear up this matter here first before it get out of the hand here you saying you want 200 amp sub panel in garage ? if so but how big you have in the main panel in house now or plan to upgrading it next year ?? i want little more details before i can say anything here first,, but if your house have 100 amp now the sisuation is very sticky here,,, i am not sure where you are from in what state so i dont know what that local codes do say about that sisuation so please give us little more details here Merci[thanks], marc poland Yes the garage is the first thing Iam building, Then the house, Wich could be a year or so. I'am wanting to get a 200a sub panel in that building know, Wich could be considered the main intill I get the house built in the future. The house I also want a 200a panel which could I guess be considered the sub or main panel. I guess I got a few questions on the whole project. Would I have to put in a 400a meter socket, that I would wire both panels to or what ideals do you have. cs409 you will not put a sub on your garage unless of course you put a pole(such as u would for a trailer)with a main service diconnection and then run yourself a sub panel to the garage! if you do the pole trick, then you can run a sub to the garage and then the house u plan to build later! you need to do a load calculation for the house and the garage to see what your total will be....aka, what size main service do u need...from there you can figure the sub panels. to be honest you will soon find that 200 amp main service will be plenty...from there you can run you a 100amp to house and 100amp to the garage... now with that said...this is what i would do. you have the garage built.... install your main service disconnect on your garage(200amp). then when you build your home, u can run your sub off this 200 amp main disconnect.! providing this garage is going to be your garage for your home also! if not and the home will have its own garage, well, the above will work but it depends on the distance to home! more info please ! good luck frenchelectrician now i can get the picture clear now but really you can put a main box in the garage now like 200 amp size there and you can run 100 amp to the house but as CS409 saying get some load demand figures for the house so you can see how big the subfeed to the house which i done this before few time but not too often i do that and is the garage will be deatached or attached becase i feel little sticky with that issuse right there and really i encoruge you talk to the inspector for final details to make sure you are ok with this plan merci, marc bigvic I would get a 320 amp meter base and install a 30 circuit 200 amp panel with main and a 200 amp disconnect side by side in the garage. Use the 200 amp disco for thr the future house. Unless the garage is attached to the home Install everything underground I never put 100 amp services in new homes no matter how many square foot the house is cs409 Poland.....most ave houses with gas kitchen, heat, etc in the usa need 100amp main. unless your going to build one HECK of a house and it be all electric a 200amp main will be more than you will need........give us the sq ft. of the home u plan to build, then list all your major electrical items, (heat, air,electric kitchen etc etc...) JimmyDee cs409, Seems like today is the day to agree with you on everything. The bigger is better crowd should do like I did a few years ago and put a recording amp meter on their all gas house and see just how many amps their little o house actually draws. I think they would be surprised. For most practical gas heated homes, a 60 amp service is overkill. The 100 amp NEC minimum will take care of their electrical needs with room to spare. Jim cs409 Jimmy, didnt u post a web site to do online load demand for a new or remodel?? another issue, as with jimmy, am old school! and i also sometimes have a hard time remembering that on a 100amp main or 200amp main, that is on each pole/phase etc etc etc.....thats a lot juice!! LOL,,,,,about time am right,,,,LOL wish i would have had my camera today.....no power in some outlets,,, found the hornets ness in attic,,,,no wire nuts, wire burned off the insulation 2ft.....burned the insulation around the area,,,,,good thing it was fire retardant,,,butttt, if it hadnt lost contact, in time!!!
