[QUOTE="SPECIAL LOCATION, post: 508524, member: 250"] BS7671 states the must not trip at 15ma, but must trip at 30ma. the real world means it is actually permissible for anything 16ma or higher to cause an RCD to trip... But that said it is also a poor design having multiple circuits sharing the same RCD.. as BS7671 also says you should design installations to avoid nuisance tripping. [/QUOTE]
