Chapter 10, Problem 1R
To determine
Name the types of receptacles and switches, and mention the number of receptacles and switches that are used in circuit A14.
Expert Solution & Answer
Answer to Problem 1R
The types of switches and receptacles used in circuit A14 are listed, and totally four switches and one receptacle are used in circuit A14.
Explanation of Solution
Discussion:
Circuit A14 is a 15-ampere branch circuit that delivers power to the hallway receptacle, the hallway lighting, and the vanity lighting used in bathrooms.
The types of switches and receptacles used in the hallway and bathrooms (Circuit A14) are listed as follows:
- • One receptacle in the hall.
- • One single-pole switch in the hall bathroom.
- • One single-pole switch in the master bathroom.
- • Two 3-way switches in the hall.
Therefore, from the above list, totally four switches and one receptacle are used in the hallway and bathrooms. Hence, a total of five numbers are used in Circuit A14.
Refer to NEC 210.11(C)(3), the receptacles used in the bathrooms are supplied by separate 20-ampere branch circuits A22 and A23.
Conclusion:
Thus, the types of switches and receptacles used in circuit A14 are listed, and totally four switches and one receptacle are used in circuit A14.
