600. DISCONNECTING MEANS<br />
A suitable service disconnecting means must<br />
be provided<br />
for each customer's source of supply. In multiple occupancy<br />
buildings a main service disconnecting means, where required<br />
by<br />
the NEC or as specified by local ordinances, shall also be installed<br />
so as to completely disconnect all of the interior wiring at one<br />
point. In accordance with NEC Section 230.71, there shall be not<br />
more than six disconnects (without a main), per service, grouped<br />
in any one location. Each service disconnect shall be permanently<br />
marked to identify it as a service disconnect. The disconnecting<br />
means must be located in a readily accessible place either outside<br />
of a building or structure or inside nearest the point of entrance of<br />
the service conductors (per NEC Section 230.70). The<br />
disconnecting means shall plainly indicate whether it is in the<br />
open (OFF) or closed (ON) position per NEC Section 230.77.<br />
Where a circuit breaker is utilized and the handle is operated<br />
vertically,<br />
the "up" position shall be the "on" position (per NEC<br />
Section 240.81).<br />
The service equipment for permanent services shall be of a<br />
type and size as required<br />

equipment" per NEC Section 230.66.<br />
The <strong>Company</strong><br />
reserves the right to seal any service disconnecting<br />
means as a general safety measure and as a protection against<br />
tampering by unauthorized persons. The <strong>Company</strong> will not be<br />
responsible for sizing service equipment.<br />
Mounting provisions for service disconnecting means and<br />
associated<br />
equipment shall be furnished and installed by the<br />
