Utility Specific Adjustments

• A Residential Load Letter is required for projects with less than 6 months of usage. No stamp needed - complete in-house (do not send to staff).
• LOAD LETTER
• Example project for reference: Simone Seward (527224)

To calculate the kilowatt (kW) from the current rating in a breaker panel for appliances, follow these steps:

1. Determine the current rating of the appliance in amperes (A).
2. Identify the voltage of the circuit (2 pole -240V or 1pole- 120V).
3. Power KW= V*A*1000

• For example, if an appliance has a current rating of 10A and operates on a 240V circuit, the power rating would be 2400W (10A x 240V). If the appliance operates on a 120V circuit, the power rating would be 1200W (10A x 120V).

Plans & docs

Site Plan Reqs

• Needs location of pole/transformer on the site plan

SLD Reqs

All Projects

• Provide a one-line diagram showing how the solar panels, inverters, meters, and grid connect.
• All interconnections must be behind the utility meter.
• The grounding electrode conductor (GEC) to the PV AC service disconnect must comply with Section 250.64(D)(1), showing the GEC tap from the main service panel and the attachment method.
• An AC disconnect must be installed to isolate the system from the grid.

Battery Projects

• Install an external blade AC disconnect near the utility meter that isolates all generation sources, including battery backups.
• Follow the Battery Backup ELD example for approved configuration.
• Battery Backup ELD example

Install Reqs

• Installed all equipment necessary to complete the interconnection, including but not limited to a lockable, Company accessible load breaking manual disconnect switch on each Generator to disconnect the Generator
