Planning the Installation

AC and DC Components including wire and breaker sizes

For a successful installation, you need to plan for AC and DC components including planning for wire and breaker sizes to be used in the power system. The AC and DC components are described in this section.

AC components include:

•AC Input

•AC Loads

•AC Disconnect and Over-Current Protection Devices

•Distribution Panels

•AC Wiring

•AC Output Neutral Bonding

DC components include:

•Batteries

•DC Disconnects and Over-Current Devices

•DC Cabling

•DC Grounding

IMPORTANT: Figure 2 does not show all required grounding and overcurrent protection.
