4.1 General
RCDs and relays shall be classified as follows:
(a) Type I RCDs and relays with I Δn not exceeding 10 mA a.c.
Operate on a residual sine wave current (a.c. r.m.s. not exceeding I Δn 10 mA) and a residual half wave pulsating dc current (d.c. r.m.s. not exceeding 20 mA) with an interrupting time not exceeding 40 ms.
NOTES:
1 AS/NZS 61008 and AS/NZS 61009 require the 10 mA sensitivity to include both Type I and General type.
Type I is defined and is Type A (sine wave and d.c. pulse) with I Δn not exceeding 10 mA a.c. with an interrupting time not exceeding 40 ms at rated residual current.
General type has I Δn and may be 6 mA to 500 mA with an interrupting time not exceeding 300 ms at rated residual current. They may be Type A (sine wave and d.c. pulse) or Type AC (sine wave).
AS/NZS 61008.1 and AS/NZS 61009.1 require the General type with I Δn not exceeding
10 mA a.c. to be marked ‘GENERAL TYPE, NOT FOR PATIENT AREAS’.This applies to all General types with I Δn not exceeding 10 mA a.c. both Type A and Type AC irrespective of the number of poles.
2 AS/NZS 3003 requires, for patient areas, a leakage protection device (LPD). This is a Type I RCD complying with AS 3190, AS/NZS 61008 or AS/NZS 61009 and additionally should switch all live conductors, i.e. a two pole unit needs to switch active and neutral.
(b) Type II RCDs and relays with I Δn exceeding 10 mA but not exceeding 30 mA.
NOTE: This is a general use type in AS/NZS 61008.1 and AS/NZS 61009.1.
(c) Type III RCDs and relays with I Δn exceeding 30 mA but not exceeding 300 mA, without selective tripping time delay characteristics.
NOTE: This is a general use type in AS/NZS 61008.1 and AS/NZS 61009.1
