What is the distance that must separate the emergency shutoff switch from the spa?

  1. 3 feet

  2. 4 feet

  3. 5 feet

  4. 6 feet

The correct answer is: 5 feet

The correct answer of 5 feet reflects the safety requirements to ensure that an emergency shutoff switch for a spa is adequately distanced from the water's edge. This distance is crucial for preventing accidental contact with the switch while someone may be in or near the water, thereby minimizing the risk of electrical shock. Additionally, the 5-foot separation helps ensure that the operator can easily and safely access the shutoff switch without being in a position that could expose them to water hazards, which can conduct electricity. These safety guidelines are generally derived from the National Electrical Code (NEC) and are designed to prioritize user safety in environments where water and electricity are in close proximity.
