You've got the general idea, but let's break it down and add some key details to ensure compliance with NEC Article 680 (Swimming Pools, Fountains, and Similar Installations). Specifically, we'll focus on 680.26(B) (Perimeter Equipotential Bonding).Here's a breakdown of your understanding and some necessary clarifications: Perimeter Equipotential Bonding Conductor



Correct

A

solid copper conductor is required. Correct

NEC 680.26(B)(2) mandates a minimum size of

8 AWG. Correct

It must

completely encircle the splash pad. Placement

It must be

18 to 24 inches (450 mm to 600 mm) from the inside walls of the splash pad and at a depth of 4 to 6 inches (100 mm to 150 mm) below finished grade. (See 680.26(B)(2)(a) and (b)). Connection to the Reinforcing Steel (Rebar)



Correct

The #8 solid copper conductor needs to be bonded to the reinforcing steel (rebar).

Important

There must be at least

4 points of connection between the bonding conductor and the rebar. These points must be spaced approximately equidistantly around the perimeter, but if the rebar is in a square or rectangular grid, one connection can be at each corner. Method

Use listed pressure connectors or clamps rated for direct burial and for connecting copper to steel.

Bonding Metal Components



Correct

Metal parts (ladders, handrails, water features, equipment, etc.) that are within 5 feet of the inside wall of the splash pad MUST be bonded to the equipotential bonding grid.

Connection to Rebar vs. Perimeter Wire

You can bond metal components directly to the rebar grid OR to the perimeter bonding conductor, OR both. The NEC doesn't specify which is mandatory, but good practice often dictates using the closest and most direct connection point. Make sure each connection has a rated connector.

Correct

Use

#8 AWG solid copper or larger for bonding these metal components. Important Considerations and Common Mistakes



Concrete Encapsulation

The bonding conductor must be buried in the ground or encased in concrete. It cannot be exposed.

Direct Burial Rated Connectors

Crucially, all connectors used for bonding must be listed for direct burial. Regular electrical connectors are not acceptable. Look for connectors specifically designed for grounding and bonding in wet environments.

Water Features as Equipment

Pay close attention to any metal components within the water features themselves. Pumps, filters, metal piping, and other metallic parts of the system must all be bonded.

Bonding Pumps and Electrical Equipment

Don't forget to bond the pump motor frame and any other electrical equipment associated with the splash pad to the bonding grid or the equipment grounding conductor (EGC). This is crucial for safety.

GFCI Protection

Remember that GFCI protection is generally required for all 120-volt through 240-volt receptacles and equipment serving or near the splash pad.

Inspection

This work will be inspected. Make sure you have all the appropriate permits and are prepared to demonstrate compliance.

Documentation

Keep a record of your bonding and grounding connections. This will be helpful for future maintenance and inspections.

In Summary

Your understanding is largely correct, but the devil is in the details. Focus on using the correct materials (solid #8 copper, direct burial rated connectors), maintaining the proper distance and depth for the perimeter bonding conductor, and ensuring all metallic components are properly bonded. The key is compliance with Article 680.26(B) of the NEC.

Recommendation: Always consult the latest edition of the NEC (National Electrical Code) and your local electrical inspector for the most up-to-date requirements and interpretations. They will have the final say on whether your installation is compliant. They can also clarify any local amendments or interpretations that may apply in your specific area. It's always better to ask questions before* you start the work! Flag for review
