Frequently Asked Questions
What is a protection device schedule?
A protection device schedule is a register of all circuit breakers, fuses, and relays in an electrical installation. It documents device types, ratings, trip settings, and discrimination status. Required by IEC 60947 and BS 7671 Regulation 514.9 for installation documentation.
What should a protection device schedule include?
Key fields include device tag, location/switchboard, type (MCB/MCCB/ACB/Fuse/Relay), manufacturer and model, rated current, breaking capacity, all trip settings (long time, short time, instantaneous, earth fault), curve type, upstream device, and discrimination verification status.
Why is breaking capacity important in a protection schedule?
Breaking capacity (Icu) must exceed the prospective fault current at the installation point. A device with insufficient breaking capacity may fail to clear a fault safely, causing catastrophic failure. IEC 60947-2 and BS 7671 Regulation 434.5.1 require this verification.
