[RE-wrenches] NEC 705.12(B)(2)(3)(c) intention

[August Goers]

Hi Wrenches –



Now that we’re in the 2014 NEC, we’ve increasingly been using the NEC
705.12(B)(2)(3)(c) interconnection method:

This is a great way of putting lots of PV on a panel when there are few
loads. As long as the total breaker rating (excluding the supply breaker)
equals the bus rating or less, we’re good to go. However, we recently ran
into a panel that had a lug subfeed kit installed in it.



Do you think the intention of the code is to allow something like shown in
this sketch?





Cheers,



August
