Circuit Breaker Protection and Total DC Charge Load
For proper installation, adhere to industry electrical standards for both the cable and DC breaker sizing. These standards ensure a safe and reliable operation. The ESS is required to have circuit breaker protection on the DC output of the rectifier. Table 6 outlines the maximum current rating for each ESS model.DC Circuit Breaker Installation
Once the appropriate size breaker is determined, install the breaker in the rectifier cabinet. Installing the breaker will allow any service team to disconnect the ESS from the power bus. If there is an existing DC circuit breaker installed for lead acid batteries, it may be sufficient to use that breaker as the lead acid batteries will be removed. Check with the project coordinator before utilizing an existing breaker. In addition, verify the breaker size and ESS charge requirements described in Table 6.
