Pool electrical work is governed by one idea: keep every conductive thing a swimmer can touch at the same electrical potential. That is equipotential bonding, a bare 8 gauge copper loop tying together the pump, ladder cups, rails, metal within the shell and the perimeter itself. Diagnosis on existing pools starts there, with continuity testing of the bonding grid, then moves to GFCI protection on pump and lighting circuits and the condition of underground conduit runs.
Montgomery's pool season effectively runs April through October, and the equipment works hard through the same heat and humidity that stresses everything else electrical here. Pool builds concentrate in Wynlakes, Hampstead, McGehee Estates and out the Vaughn Road corridor, where new construction gets bonding right at build time. The older pools closer in are where we find bonding grids that were never completed, corroded lugs at the pump, and pre GFCI era light circuits that fail modern testing.
Pool circuits, equipment replacement wiring and bonding work are permitted through the City of Montgomery Inspections Department, and pool inspections are among the strictest the city runs, for good reason. The NEC's Article 680 rules apply: GFCI protection on pump and low voltage transformer circuits, burial depths and conduit types for underground runs, receptacle and switch distances from the water, and the bonding grid verified before decking hides it.
The failure that scares experienced pool electricians is the tingle report, a swimmer feeling current at the ladder or in the water. That is a bonding or fault condition and we treat it as an emergency, pool closed until found. Subtler field realities: variable speed pump drives that fail from undersized or corroded supply conductors, niche lights whose cords wick water up the conduit into the junction box, and GFCIs that trip in humid weather because a splice underground has been wet for years.
Technician insight
On Montgomery pools built before the perimeter bonding rules, the grid usually ends at the pump. The deck, rails and water were never tied in, which tests fine on a dry day and shows up as a tingle the first time a fault or stray voltage appears. Continuity testing the whole grid is the only way to know.
Tingle at the Ladder in a Wynlakes Pool
A homeowner reported a faint tingle at the ladder after a pump replacement by a pool company. The new pump's bonding lug had never been connected, breaking the grid. We closed the pool, reconnected the bonding, verified continuity across ladder, rails, and water bonding fitting, added the GFCI breaker the pump circuit lacked, and retested under load before the family swam again.

How it works
- 1
Equipment Pad Evaluation
Site evaluation at the equipment pad: bonding continuity, GFCI function, conductor condition and conduit routing.
- 2
Quote and Permit
Written quote, with permit filed for circuit, bonding or equipment wiring work.
- 3
Article 680 Installation
Installation to Article 680 requirements, with bonding photographed before anything is buried or covered.
- 4
Inspection and Live Testing
City inspection, then live testing of GFCIs and equipment with the pump running before the pool reopens.
Pricing
Pool pricing turns on trenching distance, deck and landscaping obstacles, and whether bonding must be retrofitted. A pump circuit to a pad near the house is the base case; a 100 foot trench, cutting deck to reach an incomplete bonding grid, or a spa circuit through finished space each add real labor. Written quotes itemize the digging separately so you can see it.
