ICC Residential Electrical Inspectors Practice Exam

What type of circuit must the receptacle for a permanently installed pool be connected to?

1. dedicated circuit

2. general purpose branch circuit

3. GFCI circuit

4. lighting circuit

The correct answer is: general purpose branch circuit

The receptacle for a permanently installed pool must be connected to a dedicated circuit. This type of circuit is specifically intended for one particular load, ensuring that it can handle the power requirements without being affected by other devices or appliances. Dedicated circuits help to minimize the risk of overloading and ensure compliance with the National Electrical Code (NEC), particularly for pools and hot tubs, which have specific electrical needs for safety and functionality. While it is also essential for pool receptacles to be ground-fault circuit interrupter (GFCI) protected due to the wet environment, this protection is not the same as requiring a dedicated circuit. General-purpose branch circuits cannot guarantee the exclusive use necessary for pool equipment, which could lead to tripping and operational issues. Likewise, lighting circuits are not appropriate, as they serve a different function and are not suitable for the demands of pool equipment. Thus, prioritizing a dedicated circuit ensures safety and reliability for a permanently installed pool.
