According to California's seismic requirements, electrical equipment weighing more than how many pounds must be seismically braced when installed above grade?
Correct Answer
A) 20 pounds
California Building Code Chapter 13 and CBC Section 1613 require seismic bracing for electrical equipment weighing more than 20 pounds when installed above grade. This lower threshold compared to other states reflects California's high seismic activity and the need to prevent electrical equipment from becoming projectiles during earthquakes.
