Below are the system weights and Current loads of the iEFIS Explorer and Challenger. We recommend putting all EFIS system components on a 5 Amp Circuit Breaker. If radio and transponder are used, these can be placed on another 5 Amp Circuit breaker. If autopilot is used, both servos can share another 5 Amp Circuit Breaker.
