1. That's a really big question and the really big answer is too big for a mailing list. Search on the web for descriptions and/or comparisons. 2. The IEC standard is an international agreement. I suppose the GFCI is a US-only (or NA-only) specification. Fault currents are obviously half with 120 V supplies versus 230 V supplies. At 230 V, 5 mA would cause nuisance tripping and problems with protective conductor currents due to capacitance from L to PEC. 3. ELCBs required a PEC connection, so if the PEC is broken, the protection does not work. RCCBs detect the difference between L and N currents and do not use a PEC connection.

From: Vincent Lee [mailto:[email protected]] Sent: Thursday, February 16, 2017 3:04 AM To: [email protected] Subject: [PSES] Questions on RCB, RCCB and ELCBs Hi all, I am Vincent, newbies in Product Safety. Hence, I sincerely hope to seek your professional answers to my following questions, 1) What are the major differences between RCB, RCCB, GFCI and GFEP ? 2) If the human-let-go-current-threshold is about 10mA, why does IEC 61008 RCCBs used in Household being specified at 30mA trip current while GFCI used in Household are specified at 5mA (+/- 1mA) ? 3) I heard that Residual Current Circuit Breaker are replacing Electrical Leakage Circuit Breaker, in what ways are RCCB better than ELCB for electrical safety protection that causes ELCB being replaced?
