A short-duration surge, due to transformer inrush current, willoccur at turn-on or during a short AC power loss. This surge canbe as high as 400 amps. During this surge, the line voltage at thecabinet must not drop below 80% of the rated line voltage. Selecta 40 amp breaker or fuse for the transmitter using the aboveinrush current information.2.3.3 AC mains Disconnect LocationThe circuit breaker panel should be located near the transmitterin a well lighted area. As a safety precaution, controls fordisconnecting the main power service supplying the transmittermust be convenient to the operator and maintenance personnel.Breakers must be clearly labeled.
