B. Variance Request (if applicable)
The Customer or the Customer’s Contractor can request a Variance Request review from PG&E if the project is
unable to meet the requirements described in the Distribution Interconnection Handbook and Greenbook, available
at www.pge.com/dih and www.pge.com/greenbook
. The Variance Request must be submitted with the
Interconnection Application and include the following.
1. Description of the proposal for which the Customer is requesting approval.
2. Customer name and project address.
3. Copy of the Custom Single Line Diagram or electrical drawings (Include the equipment, location, and/or
distances for the proposed work).
4. Color photos of the Customer’s area or section for the proposed work.
5. Manufacturer specification drawings for unapproved equipment that the Customer is requesting an approval.
C. AC Disconnect Switch Guidelines
PG&E recommends that customers installing an inverter-based generator consider also installing an AC Disconnect
Switch to facilitate maintenance of the Customer’s equipment (i.e. inverter, PV arrays, etc.). The AC Disconnect
Switch provides the additional benefit of allowing PG&E to isolate the Customer’s generator from the utility’s
Distribution System without having to interrupt service to the customer’s facility or residence.
Customers are not required to include an AC Disconnect Switch when the facility has a single-phase self-contained
electric revenue meter (i.e. 0-320 amp panel). However, if the Customer does not install an AC Disconnect Switch,
the revenue meter may be temporarily removed by PG&E due to an emergency or maintenance on PG&E’s system to
isolate the Customer’s generator from the electric distribution system. Removal of the revenue meter will result in loss
of electrical service to the Customer’s facility or residence.
An AC Disconnect Switch is required for a Customer with:
Inverter-based interconnections having a three-phase self-contained meter or a transformer-rated meter
(i.e. all meter panels or switchboards employing the use of potential and current transformers).
Non-inverter based generators, including rotating or machine-based generators - irrespective of whether the
service meter configuration is transformer-rated or self-contained.
Inverter and non-inverter based generators that do not have overcurrent protection at the point of
interconnection.
D. Custom Single-line Diagram (SLD) (if applicable)
The Custom SLD must include the information below for identified equipment.
1. Manufacturer, model number, nameplate rating, quantity:
a) Inverter(s), PV or wind turbine generators, AC Disconnect Switch, generation output meter and
instrument transformers.
2. Electrical rating and operating voltages:
a) Service panel, circuit breaker, and other Generating Facility protective devices
3. Location of:
a) Customer’s loads relative to the Generating Facility, and the interconnection with PG&E’s Distribution
System.
b) AC Disconnect Switch.
4. Description of how the power output from the inverter is connected to the main service panel via a branch
breaker. The ampere rating of this branch breaker and the main service panel breaker must be compatible
with the output rating of the Generating Facility. The output rating is based on the total nameplate rating of
the inverter.
