SPARKY BREAKDOWN — EP 19
NEC 680 Pool Bonding (The Part That Finally Clicks)
joshthesparky4 · Josh The Sparky
Most electricians think bonding is just connecting metal together.
That’s not what it’s actually doing.
This is a quick breakdown of NEC Article 680 bonding requirements — and the concept that makes it finally make sense.
Bonding isn’t about connections.
It’s about eliminating voltage differences in the pool area.
Article 680 is focused on keeping everything at the same electrical potential so current has no reason to flow through a person.
It controls:
• Equipotential bonding of conductive parts
• Voltage gradients in and around the pool
• Shock risk between objects you can touch at the same time
• Equipotential Bonding
All conductive parts are tied together so they stay at the same voltage
• No Voltage Difference = No Current Flow
If everything is at equal potential, there’s no path through your body
• This Includes More Than You Think
Metal parts, pool structure, decking, equipment, and more
• Thinking bonding = grounding
• Missing parts that need to be bonded
• Assuming “it’s metal so it’s fine”
• Not creating a true equipotential plane
• Treating bonding as optional instead of critical
Around water, even small voltage differences can be dangerous.
Bad bonding =
• Shock hazards
• Failed inspections
• Real liability if someone gets hurt
• Bonding = equalizing voltage, not just connecting metal
• The goal is an equipotential zone
• Grounding and bonding are not the same thing
• Missing one component can break the whole system
• Expect questions on equipotential bonding grids
• Know what must be bonded under NEC 680
• Understand why bonding works — not just rules
• This is a high-miss topic on exams
If you think bonding is just “hooking metal together”…
you’re missing the whole point. ⚡
