Rank: New forum user		We ( Contractor & Safety Advisor) are discussing what would be the tripping limit (mA) for GFCI installed. Our installed GFCI is adjust at 200mA, while our advisor said it must be 30mA to protect workers from electric shock. Is there any code/standard that clarify the tripping limit of GFCI at electric supply with 240 Vac.? How we can select which safety device(GFCI,ELCB,RCD) need to be used as site situation ?

You are using the term GFCI this is a USA National Electrical Code term, where in the world are you relating this question to?
