Pool bonding is a code area where older Florida installations frequently fall short, and it is the one electrical defect around a pool that is genuinely dangerous. The requirement is an equipotential bonding grid tying the pool shell, the perimeter surface, the ladders and rails, the pump motor, and any metal within reach into a single bonded system so there is no voltage difference between them.
Homes with pools built before the current bonding requirements often have the pump bonded and nothing else. That gets found during a remodel, an equipment replacement, or an inspection, and it has to be corrected before the work can pass.
The related work is the equipment circuit itself. Pool pumps need GFCI protection and a disconnect within sight of the equipment, and variable speed pump conversions frequently need the circuit revisited.
Technician insight
If you feel a tingle on the pool ladder, get out and call someone that day. That is a bonding failure and it does not get better on its own.
