randynavarro Posted January 19, 2010 Report Share Posted January 19, 2010 While trying to answer this for myself, I realized I've never come across this situation in the field, otherwise I'd have an answer. Getting ready to do some damage on my place, but need some more amps in the garage. . . Link to comment Share on other sites More sharing options...
Jeff Remas Posted January 19, 2010 Report Share Posted January 19, 2010 Yes. You can run a sub panel off a sub panel then run a sub panel off of that sub panel then run 2 more sub panels off of that sub panel then a sub panel off of each of those sub panels and so on and so on and so on. As long as your calculated loads all match and all feeders are properly wired. Link to comment Share on other sites More sharing options...
randynavarro Posted January 19, 2010 Author Report Share Posted January 19, 2010 So let me get this straight Jeff - I can run a sub panel off a sub panel? Link to comment Share on other sites More sharing options...
Marc Posted January 19, 2010 Report Share Posted January 19, 2010 My practice, when I was contracting in electrical, was to keep the breaker serving the subpanel at no more than half the ampacity of the main breaker. The reason for this was to reduce the chance of a fault on the subpanel from tripping the main breaker. It's a big inconvenience to the customer when that happens. The same plan is applied for any panel feeding off of a subpanel. Marc Link to comment Share on other sites More sharing options...

Jeff Remas Posted January 22, 2010 Report Share Posted January 22, 2010 So let me get this straight Jeff - I can run a sub panel off a sub panel? I think so, not sure but think so.[:-crazy] Link to comment Share on other sites More sharing options...
Richard Saunders Posted January 22, 2010 Report Share Posted January 22, 2010 No, you cannot. No more than you can run a main panel off of a main panel. A sub panel off of a sub panel would be a sub sub panel, so semantically it is not possible to run a sub panel off of a sub panel. Link to comment Share on other sites More sharing options...
plummen Posted February 7, 2010 Report Share Posted February 7, 2010 why not just install a properly sized service and panel to take care of the load if theyre all in the same area? then you can feed the garage panel directly from there,or am i missing something here?

Thanks for trying - you're not missing anything. I'm getting ready to rip out the original service for a major remodel. However, before I do that, I need to get more power to the garage in order to start and complete the remodel. You know, power tools, tablesaw etc.. So, I need new sub to the garage and then I'll upgrade the main service at the house. Link to comment Share on other sites More sharing options...
