110v vs. 220v Wiring | DoItYourself wwwyourself››Home AutomationSafety Concerns110V Uses Versus 220V UsesBasic Wiring of BothWhile both high amperage and voltage can mean danger in the event of an electric shock, the amount of amperage required for a fatal shock can be as little as 80mA. Thus, higher current can be more dangerous than higher voltage; however, since voltage and amperage are directly proportional (in conditions that offer the same resistance), 110v wiring is usually considered safer to work with because it uses fewer volts and as such can only carry half as much current as 220v wiring. Although it's..See more on doityourself Understanding 220 and 230 Volt Wiring | DoItYourself wwwyourself››Home AutomationThis is the same reason 110 volt circuits are now 120 volt circuits. However, people still use the old 110/220 volt terms in conversation, but in reality those have not been used since the 1960's and 1970's in most locations. The design relies on the principals of electrical phases.
