* In-rush current occurs for 10 to 12 milliseconds
HP recommends the use of magnetic-type circuit breakers, which are capable of handling
large in-rush currents for short durations (10 to 12 milliseconds) and are rated adequately
for the steady state currents.
* Data assumes no other devices share the circuit breaker.
Note
Circuit breaker rating must be adequate for the total current drawn by all
devices on all electrical paths that share a circuit breaker.
