Question 1

Equipotential bonding required by 680.26 shall be installed to reduce ____ in the pool area.

Accepted Answer

Equipotential bonding is required to reduce voltage gradients in the pool area. Voltage gradients can be caused by electrical currents in the water, and can potentially lead to electric shock or other safety hazards. Equipment grounding and GFCI protection are also important safety measures in pool areas.

Question 2

A junction box for an underwater application shall be comprised of ____, brass, suitable plastic, or other approved corrosion-resistant material.

Accepted Answer

The answer of A junction box for an underwater application...

Question 3

Unit heaters shall not be mounted over the pool or`within the area extending ____ ft horizontally from the inside walls of a pool.

Accepted Answer

The answer of Unit heaters shall not be mounted over...

Question 4

Where a permanently installed pool is installed, no fewer than one 125-volt 15- or 20-ampere receptacle on a general-purpose branch circuit shall be located a minimum of ____ ft, but no more than 20 ft, from the pool's inside wall.

Accepted Answer

According to the National Electrical Code (NEC), a receptacle must be located at least 6 feet away from the inside wall of a permanently installed pool to ensure safety and compliance with electrical standards.

Question 5

Unencapsulated structural reinforcing steel in pools shall be ____.

Accepted Answer

Unencapsulated structural reinforcing steel in pools must be bonded together by steel tie wires or the equivalent to prevent electrical current from building up and causing damage to the pool or harm to swimmers. Grounding, equipotential bonding, and encasing in corrosion-resistant materials are all important for pool safety, but they do not directly address the issue of unencapsulated structural reinforcing steel.
