[QUOTE="SPECIAL LOCATION, post: 211146, member: 250"] 415 page 59 (red book) [not gone green yet!] specifically 415.2.2. where it says that the resistance between two simultaneously accessible exposed conductive parts and extraneous conductive parts shall be "less than or equal to 50v / the current rating of the protective device." Which means the voltage difference between two bits you can touch should not be allowed to rise above 50v in A.C. systems. AKA 50v "touch voltage" [/QUOTE]
