This equipment can be de-energized by switching off the main breaker.
CRITERIA NEEDED FOR THIS INTERCONNECTION
CRITERIA NEEDED FOR THIS INTERCONNECTION
The example to the right shows what your setup might look like for this type of interconnection. Depicted is a main disconnect (MSP) attached to a meter on a pedestal detached from the main home. This main disconnect is feeding another panel on the home.
This interconnection has the following requirements that need to be met before it can be considered:
Sub Panel is on the exterior of the home or is easily accessible on the interior of the home
"easily accessible" will mean back to back or within 10 feet of the MSP/Meter.
Interconnection in the MSP is not possible or otherwise not preferred.
In the case on the right, interconnecting on the MSP would require trenching to the detached meter, so it would not be preferred.
There are 2 available stabs to accommodate our PV breaker.
If you the panel is full but the load center allows tandems you can consider this condition met.
There must be no code violations present in and around the MSP.
If there is a plan in place to resolve code violations, then you can consider this condition met.
There must be sufficient available backfeed for the amount of PV we will be landing in this load center.
