Heavy Duty Safety Switches main Features:-

In the industry we are talking about a “six-handle rule.” The source of this rule is found in Section 230.71(A) of the NEC, which indicates in general “each service” or “set of service entrance conductors” shall have “not more than six switches and sets of circuit breakers.” The requirement to group these service disconnects is found in Section 230.72.


A PV disconnect can be consider as an additional disconnect to the set of 6 corresponding the six rule or the six allowed disconnects to a dwelling unit or a single household. Anyway there are limitation and possible interpretations to the rule and those must be cleared by AHJ. A careful reading of the Code does not support this interpretation./p>

Load-side interconnection. Code Section 705.12(D) allows for a load-side interconnection, provided that certain requirements are met. The benefit of a load-side connection is that there is no need to add a seventh disconnect for the PV system. However, the load-side connection is subject to the 120% rule found in Section 705.12(D)(2)./p>

New service. Another option is to have the utility supply added separate to that building together with a separately meter for PV production. While Section 230.2 generally allows only one service per building, more services are permitted in accordance with Sections 230.2(A) through (D). According to Section 230.2(A)(5), the existence of parallel power production systems is one of the special conditions under which additional services to a building are allowed.

Supply-side interconnection. A final option is to interconnect the PV system between the service equipment and utility meter associated with the house loads. In this scenario, the 120% rule does not apply. Instead, the rating of the service limits PV system capacity, according to Section 705.12(A). The benefit of supply-side interconnection is that that it allows for the installation of more PV capacity as compared to a load-side interconnection.
