Question
Chapter 22.3, Problem 1R
To determine
Name the circuit that provides the power supply to the hydromassage bathtub.
Expert Solution & Answer
Answer to Problem 1R
A9 circuit supplies the power to the hydromassage bathtub.
Explanation of Solution
Description:
Hydromassage bathtub is a regular bathtub with recirculating piping system and an electric pump. The electric pump in the hydromassage bathtub circulates the water. Hydromassage bathtub is also termed as a whirlpool bath.
A dedicated branch circuit A9 supplies the required power to the hydromassage bathtub. A9 branch circuit is a 15 A, 120 V electrical circuit.
Conclusion:
Thus, the A9 circuit supplies the power to the hydromassage bathtub.
