What standard defines that a power switch should break the hot wire and not the neutral wire?  



RE: power switch

In the ANSI world, NEC (NFPA 70).

However, no electrical engineer worth the salt would need a standard or a law to decide this. Standards and codes are intended for harmonization and minimum safety, not for every engineering decisions.

I guess this is what happens when the small signal electronics engineer gets on the other side of the power supply!  



RE: power switch

I found it; 2008 NEC 70 Sections 380-2, and 230-42, and 100-A.
