🔍 Key Concepts

• Human body resistance vs. voltage level and how skin acts as an insulator at lower voltages • Difference between “let-go” current/voltage” and skin puncture voltage • Typical industrial power system voltages (208, 480, 600, 1000 VAC) and which are more associated with arc flash / breakdown of insulation

💭 Think About

• Think about at what approximate voltage the outer layer of skin is no longer protecting you and the current can pass almost as if the skin were not there • Compare the listed voltages to common building and industrial power systems and recall at which level electrical safety standards begin to treat contact as almost certainly penetrating the skin • Eliminate answers that are more associated with normal utilization voltage (where skin resistance still matters) rather than actual dielectric breakdown of the skin

✅ Before You Answer

• Verify which voltage level is generally cited in marine/industrial electrical safety references as the point where skin resistance becomes negligible • Check which of these voltages is commonly associated with dielectric breakdown of dry human skin rather than just a dangerous shock • Be sure you distinguish between physiological effects of current (mA) and the voltage level where skin is punctured; they are related but not the same concept
