Appendix F: Determining the Circuit Breaker
Size

Revision History

Version 1.0 January 2019: first release

Introduction

Inverters should be protected by circuit breakers. This document describes how to
determine which circuit breaker to use in three phase commercial installations.

Using Transformers in Commercial Three Phase
Inverter Installations

Using transformers in a commercial installation is optional. In most cases a
transformer is used to connect the installation to the medium voltage power grid. The
following figure illustrates a typical transformer and commercial three phase inverter
installation topology.
