trentw7231 Posted January 3, 2014 Report Share Posted January 3, 2014 Does a 4 wire subpanel in a detached building need to have its own disconnect? Quote Link to comment Share on other sites More sharing options...
Marc Posted January 3, 2014 Report Share Posted January 3, 2014 No. Not as long as it has one in the main disconnect. Marc Quote Link to comment Share on other sites More sharing options...
Douglas Hansen Posted January 3, 2014 Report Share Posted January 3, 2014 Marc - I think you missed the part where he said "detached building." Every building with a panel requires a disconnect at that building in accordance with 225.32. The rule essentially mirrors the rule for service conductors.

Marc Posted January 3, 2014 Report Share Posted January 3, 2014 Didn't miss anything Douglas. Seems I've had it wrong for decades. Didn't know a local main disc was required on a subpanel that served a detached structure. No muni inspector has ever written me up for it.

trentw7231 Posted January 3, 2014 Author Report Share Posted January 3, 2014 Thanks. I thought each building had to have its own disconnect. I couldn't locate the literature. Quote Link to comment Share on other sites More sharing options...
Jerry Simon Posted January 3, 2014 Report Share Posted January 3, 2014 That rule is violated by thousands of Chicagoland detached garages. . . Quote Link to comment Share on other sites More sharing options...
Les Posted January 3, 2014 Report Share Posted January 3, 2014 Maybe Douglas will put the rule into a historical perspective. ie: when why etc. Quote Link to comment Share on other sites More sharing options...
kurt Posted January 3, 2014 Report Share Posted January 3, 2014 That rule is violated by thousands of Chicagoland detached garages. . . Isn't there an amendment or exception thru local 134? Quote Link to comment Share on other sites More sharing options...
Jim Port Posted January 3, 2014 Report Share Posted January 3, 2014 The disconnect may be as simple as a single or double pole toggle switch, a pullout disconnect, 6 throws or less or a main breaker. The NEC has required this for as long as I can remember. Why a labor organization would have an exception to a code escapes me. Quote Link to comment Share on other sites More sharing options...

Jim - one of the limitations of the internet is that you can't always see when Kurt has his tongue firmly implanted in his cheek. I think this is one of them.

Jim Port Posted January 3, 2014 Report Share Posted January 3, 2014 Thanks Doug, maybe I should have seen his smirk in his avatar. [] Quote Link to comment Share on other sites More sharing options...
kurt Posted January 3, 2014 Report Share Posted January 3, 2014 Yeah, I was kinda making a joke to Jerry. Although, we do operate in a code soup here. Every municipality has it's own adoptions, and the CoCBD municipal building code is a swamp. I dream of the simplicity of the IRC. Quote Link to comment Share on other sites More sharing options...
