Here are some tips to help you prevent common mistakes when bonding equipment around your pool or spa. Always remember to check your local building codes for more detailed information.
Tip #1: Know the Difference
It’s important to understand the difference between bonding and grounding around a swimming pool and spa. Unlike grounding, bonding connects and equalizes any potential stray voltage going to metal parts around the pool. This creates a safer swimming environment.
Tip #2: Ground and Bond Thoroughly
Anything metallic and larger than 4 inches that is within 5 feet of the pool or spa must be bonded.
Tip #3: Make Sure Everything is Connected
Simply grounding the equipment to the earth will not bond the system. Everything must be connected in order to equalize any potential stray voltage in or around the pool.
Tip #4: Use the Correct Connectors
Make sure you have the best connection possible when hooking up the bonding and grounding wires to a piece of equipment. This ensures that any current that needs to move has a clear path. Verify correct connector requirements with your local building codes.
Tip #5: Use the Correct Wires
Using unsuitable wires can leave your system vulnerable to environmental damage. Most electrical codes call for 8-AWG solid copper wire. Check with your local building codes to ensure that you use the correct wires in the correct locations.
Tip #6: Know Which Elements Need Bonding
Unless the plastic or fiberglass elements come equipped with a bonding lug, they generally do not need to be bonded.
