And I'll need four conductors, and adding additional ground bar for the right side of the panel. Thanks aaron! So if I install a 60 amp sub panel and the feeder cables would be 20 to 22 ft in length and that sub panel would have 12 spaces. He added, I put out 8 new boxes of 200 amp panels, and 8 boxes of 100 amp panels, yesterday, and they were gone before my shift ended! There is no more in the back room to put out. Perhaps because it is cheaper at the box store than buying at the local electrical supply houses? he said. The floor sales man told me, they can't keep them in stock fast enough, as local builders are buying pretty much every one, and every work box the store puts out on the floor. And if I can get them from amazon or some place is fine, because my local box stores are regularly out of stock of power panels. and or links to products you recommend, I would greatly appreciate this. Tell me, what size panel you recommend I buy? Tell me what size power feeding cables, will be required, 'to power the sub panel', and the length of those cables will probably be 20-22 feet? is my thinking, not that I'm planning on buying a EV vehicle any time soon if ever, but, it could be a bonus for selling the house in the future, to some one who does have or will have a EV vehicle. for an occasional use of a 230 v power tool, or future charging station for a EV automobile. lighting circuit, for a bed room.Ī 15 amp 120v receptacle circuit for a bed room.Ī 20 amp circuit for receptacles in side a garage.Ī 15 amp circuit for lighting inside a garage.Ī 20 or 30 amp 220v circuit for the garage. It is looking as if there is not going to be enough space/circuits in the main 200 amp panel for all the circuits being from my new addition, with out grouping the lighting needs from several rooms onto one circuit, and doing the same for the receptacles, so, Can we visit this topic again? This time with some changes to what the power needs 'drawn from the sub panel' would possibly be.Ĭurrently the train of thought for the sub panel is that There would be:Ī 15 amp 120 v. We can help you decide on what size service you should run, but you have to tell us what you intend to power up ! If you have less than 6 circuits in the sub panel, you don't even need a main breaker in it. The subpanel can have a 100A breaker, but because it is only a disconnect for the panel (ie, the 60A in the main will trip if there is an overload) Generally, you can feed say a 60A feed to the sub panel as an example. The breaker in the main panel is sized for the wire feeding the sub panel.Īgain, you need to figure out what your power requirements are first. Using 10 gauge cables would be sufficient wire size ? or 8 gauge? or the gauge that is used for electric stoves and clothes dryers?Ĥ) or can I use the #2/0 cables that I have left over when I upgraded the power feeds that now feed my main 200 amp panel from the pole at the street? But where would I attach it to at the main panel? Na, I can't use it, the breaker won't accept it. The breaker at the main 200 amp panel that will feed the sub panel, should be less amperage than the main on the sub panel? yes or no? and if true, why? and by how much less?ģ). I need to do something with, besides just lay around my house / yard as they are now.ģ) Would these cables be suitable / desirable for a 50 amp sub panel?Ģ). I have 3 individual cables of aluminum 2/0 wire, 25 feet long or so. Now the 200 amp 'main panel' has more than enough open circuits available currently. Or if not me, some one in the future, after me may want to.Īnd having a sub panel in place would be easier to wire into than the run across the ceiling and through the trusses to the main panel, I think any way.ġ) Would having a sub panel installed, increase the monetary value and desirability, of some one choosing to buy my house over another house? Ģ) Would it be advisable now to install the sub panel? or run wire conduits with jet line, to pull wires later to the main panel? and or a 30 amp 240 volt outlet for a special tool. In the future I may wish to add a 240 volt welding outlet. In the future I may wish to add additional 120 volt outlets. Been thinking lately about installing a 8 or 12 circuit sub panel in the garage instead of running wires 30 feet to the main panel in the house.
