You are correct. Section 680.51(A) does not apply to submersible motors used for water well pumps. Here's why: Scope of Article 680, Part V (Fountains)

Article 680, Part V, specifically deals with the requirements for fountains. These are decorative water features with recirculating water systems. Water well pumps, even if submerged, are not fountains.

Intended Application of 680.51(A)

This section addresses the electrical equipment associated with fountains, such as the recirculation pumps, lighting, and control equipment installed within the fountain structure or immediate vicinity.

Water Well Pumps are Different

Water well pumps are covered under different sections of the NEC. Typically, they fall under:

Article 430 (Motors, Motor Circuits, and Controllers)

This is the general article for motors and would cover the requirements for wiring, overcurrent protection, and disconnecting means.

Article 250 (Grounding and Bonding)

This is for the proper grounding and bonding of equipment, which is extremely important in wet environments like well casings.

Local Codes and Regulations

Many jurisdictions have specific codes related to well pump installations, including depth requirements, casing materials, and water quality protection.

GFCI Protection for Well Pumps

While 680.51(A) doesn't mandate GFCI for well pumps, other sections of the NEC or local codes may require it. Some typical instances: NEC 210.8(B)(5) and 210.8(F)

Could require GFCI protection for readily accessible receptacles in damp or wet locations or supplied by single-phase branch circuits rated 150 volts or less to ground, 50 amperes or less. If a submersible pump is plugged into such a receptacle, it will require GFCI protection.

Manufacture Requirements

Depending on the equipment the manufacturer may require GFCI protection.

Local Jurisdictions

Some local codes have specifically adopted GFCI requirements for water well pumps, regardless of location.

Safety

Even if not strictly required, GFCI protection for well pump circuits in residential settings is often a good safety practice due to the wet environment and potential for ground faults.

In summary, 680.51(A) does not apply to water well pumps. Water well pumps are generally covered under Article 430.

Important Recommendations


Consult the NEC

Review the current edition of the NEC.2.

Check Local Codes

Always defer to your local electrical codes and regulations. The local AHJ (Authority Having Jurisdiction) has the final say.3.

Manufacturer's Instructions

Adhere to the pump manufacturer's installation instructions and recommendations, as these may have specific electrical requirements.4.

Qualified Electrician: Ensure the installation is performed by a licensed and qualified electrician who is familiar with well pump installations and local codes. Flag for review
