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 an outdoor meter/main combo. The setup for this type of interconnection could also look like an exterior MSP beside the meter but not in a meter/main combo.
This interconnection has the following requirements that need to be met before it can be considered:
MSP can be either interior or exterior.
Remember that exterior connections are always preferred when possible.
There are 2 available stabs to accommodate our PV breaker.
If you the panel is full but the load center will allow you to consolidate the number of spaces you will need on tandems/triplexes/quads 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.
