Question { SOFT, 5561 }

why we use 110vac in overhead crains? why not 220v, 24v

Answer

for same body resistance the high voltage causes high
currents to flow through the body. for ex body resistance is
20kohm(generally).220v gives 11ma.for 110v it is 505ma,
below the danger value. if it incase not not grounded
properly it may helpful to limit the shocking current
