[QUOTE="adammid, post: 316687, member: 19569"] Sidewinder, thats what i thought originally but think thats how fast it should trip when a 30mA current would flow. 30mA is the point at which the body can withstand without such serious consequences such as loss of consciousness hence why the regs state a 3omA rcd should trip in 0.4 seconds. From what i have worked out i think at 13-15mA which is the point of involuntary muscle contraction a fuse should trip within 1 second but wondered if anyone else had any other thoughts. [/QUOTE]
