Correct answer to question 10019

  • B: 22.5 ft

Explanation

The table of overhead conductor clearances over pools gives 22.5 ft above the water surface or base of the diving platform for insulated cables of 0 to 750 volts supported on a solidly grounded bare messenger or neutral. Other conductor types, such as bare open conductors, need greater clearance.
