How To Test Time Delay Rcd at Andrew Corby blog

How To Test Time Delay Rcd. 1660 series can perform basic testing of rcds, determining the tripping time (in milliseconds) by inducing a fault current in the circuit. A time delayed rcd should always be used if other rcd's / rcbo's are connected after them. It is a tt supplyand a split cu and therefore the main mcb is a 100ma time delay rcd. This will allow the other rcd's to. No problem with testing the. Distribution board rcd protecting sub main circuits can have be s type/time delayed as shown in fig 1 which act to minimize the risk of danger and inconvenience to the user for operation of downstream rcd units. Time delay rcds are identified with the following symbol s. Where an rcd with a rated residual operating current, iδn, not exceeding 30 ma is used to provide additional protection, the operating time must not exceed 40 ms at a residual current of 5. It is the same as testing an ordinary rcd but the tester may time out before it trips unless you select the time delay option on your.
