[QUOTE="SPECIAL LOCATION, post: 72429, member: 250"] I have had the opposite problem a few years back brand new RCD, (can't remember make) would NOT tip at all!!! only with test button.. Got it replaced FOC by supplier. Anyway since then I ALWAYS test RCDS before going to site... just stick a bit of flex off my snap block power it up stand-alone on my garage bench... then quick trip test! I have also had a main switch that was only making one half... Live came on, but neutral leg stayed open circuit.. so I also stick my continuity buzzer across all main isolators & MCB's before going to a CU change.. It don't take long but can save wasted time.... the only other solution IMHO is as Andy C says.. carry duplicate stock in-case of commissioning failures. :| ;) [/QUOTE]
