[RE-wrenches] 2011 code and roof discos

[Bill Brooks]

Kirk,

 

Disconnects within sight of combiner boxes will be required in 2011. Another
good reason to keep combiner boxes off residential rooftops. This is
targeting commercial rooftops where large system have no disconnects for
servicing fuses.

On that note Bill, will roof disconnects be required in the 2011 NEC?

Andrew,

 

It does not exist. We tried like crazy to get it into the 2011 NEC, but to
no avail. At the last second the proposal was put on hold until the 2014
NEC. Major bummer. For now it can only be done with AHJ approval. Many allow
it but it is not in the NEC. Alternatively you must use the sum of supply
breakers no greater than 120%. Much more restrictive.

 

Bill.
