Limitations of rcds
Nettet20. sep. 2024 · If the flow is imbalanced because of a leakage, the device will trip, and the supply will be cut off to the circuit. RCDs usually have a nominal current. Therefore, they can trip beyond the nominal value as well. However, residual current devices cannot limit the current or the voltage. NettetConsider Limitations of ENC (accuracy/source data) Planning: When planning a route on ECDIS, always consider ENC display settings and, as with paper, use the best scale (1:1). Take time to check and scan routes. It is advisable first to conduct automatic route checking, adjusting the route each time to correct the alerts generated.
