120V is actually more dangerous, because it’s enough voltage to cause muscular contraction but not instantly destroy tissue (like 480v does).120v tingles a little bit. Still prefer it over the jolt of 277v![]()
It’s why if you’re ever being really risky and checking for voltage without a meter or other electrical device, use the back of your hand. That way if it’s live, the muscle contraction will actually work in your favor and pull your extremity away from the voltage, rather than clamping your hand around it.
Just be safe; we lose enough members over time to natural causes. Don’t need to add more for easily avoidable accidents.
