Hell, a 30 amp service, if your code permitted, would almost certainly support what you need. You would be able to shut off power to the whole structure with the 60 amp breaker. You would buy a two pole 60 amp breaker and bring the power into that, then install whatever breakers you needed as branch circuits. Square D makes a very nice eight space panel in both indoor and out door configurations. But you need to be sure you will be building that house, and it should be within the decade, or the cost of 1000' of wire might not make much sense. If, however, you intend to build a full sized, to be occupied year round home on the property, then a 100 amp service might be better. You may well do better to have a meter socket and a separate main breaker or main lugs 60 amp panel. This is not an issue so much if one has a riser for a whip from a pole 30' away and you only need to buy 30' of wire.īut you are looking at 1000' feet. What sort of bites is that the ampacity of the wire that one buys is not well in sync with the size of the breakers on the market, and one tends to buy larger wire for the service than is utterly necessary. What might be worth doing, to save on the cost of the wire in the conduit, is to install a lower amp main breaker. You will not be air-conditioning this thing and it doubt that you will instal a jacuzzi, so there is zero concern that you would need more than 100 amps. If you had a 240v tool that drew 10 amps, it would draw them from both legs and leave you with 90 amps on each leg. Remember that a 100 amp panel means two 100 amp legs at opposite ends of the phase. My home is 1800sqft, with a 4 ton AC, and is serviced by a 100 amp panel, although that is a sub panel that had been the original panel, the garage has a 200 amp panel on it that powers the garage and the sub. Also find out what their attitude is toward GFIs.ġ00 amp will be vastly more than enough. Your code demands conduit? For a barn? Will they permit plastic? Very easy to work with. A 100 amp combination panel would come with one pre-installed.ģ00' from the pole is a LONG way. A main breaker is the easiest way to do that. There is a newer rule that requires that one be able to shut off all the power to a structure with six or less hand motions. Look up the meaning of "main lug" and "main breaker". These are available in exterior use (in CA most main panels are on the outside of the house). There are panels that are "combination" which means that they mount the meter and have breakers in them. It is up to you to run from that to the service panel. The power co just needs a structurally sound place to hang the meter. In a house one is the plumbing system, which serves two purposes, to make having plumbing in combination with electricity safer, and to save the minimal cost of a second rod. That is about $5 more, and your barn is not as water tight as a house. Go ahead and get an exterior style panel, even if it is going inside the barn. The smallest that you can use, I think, is a 60 amp. Why do you need power at this barn? How many hours per day/week/month/year is there any sort of load on it? A small generator might do all you need?Īssuming you actually do want a service, I cannot speak for TN, but national standards would have:Ī service panel. There is no other building on the same property with a meter and a service panel? You may not be able to power everything at once, but to get more than one circuit, you need a subpanel (or a completely new service). IOW, if done properly, you could add all sorts of lights and receptacles off a single circuit. Then, you could shut the entire barn off with the breaker feeding it in the main panel, or out at the subpanel, individual circuits. then, you can add as many circuits as you want, again, assuming your main feed is sufficiently sized. If it is larger than what one circuit will support, you'll need to run sufficiently sized new wire (a 4-wire circuit) off the main panel in the house out to a new subpanel in the barn. You have to determine what you need, and what load there is. You can put as many receptacles on a single circuit as you want. A second meter means a second base charge, separate billing in addition to whatever electricity cost you might use.better to just run it off the main panel. Unless there's a very good reason to have a separate meter, it generally doesn't make much of any sense to do it for an outbuilding. If you only have one circuit, and don't use a subpanel, you don't need anything other than what's likely there.
