We are an electrical contractor working in the city of Parkland, FL. We have a commercial job with an electrical riser that has 5 separate main breakers, the way the manufacturer configured it (and the EOR approved it via submittals) was having 5 separated, service-rated, MLO panelboards, where the utility enters on the panelboard lugs and the load exits thru a breaker mounted on the bars. The installation is completed now and we are trying to call for a 30 Day Temporary Power for Testing. The panelboard complies with all the kAIc, and ratings required. The electrical inspector is rejecting the installation saying that the panelboard bars will always be energized by the utility (which is true). Still, our point is that you are allowed to have a MLO, MDP with no more than 6 mains installed and that configuration will also have the bars always energized. But we may be missing something here. The applicable CODE version for this project is NEC 2014.
We believe that even 2017 NEC, Section 230.71 allows up to six switches or circuit breakers or a combination thereof as the service disconnect for an electrical service, as long as the switches or circuit breakers occupied the same electrical enclosure, or the switches or circuit breakers were installed in six separate enclosures but remained in a group together.
Any comments will be really appreciated.
