"They've created an immense hazard for the homeowner, " Brotz says. At present it is necessary to equipotentially bond all exposed conductive parts of any electrical equipment in the defined zones. It is not on its own a federal requirement and adoption rates for NEC code updates can vary, so it is important to be aware of your local requirements as some may actually exceed requirements of the NEC. "It takes 120 volts and turns it into 1, 200, " Brotz says. The strut risers that support the pool controls were only fastened to the concrete slab with some L brackets. They'll then wrap the wires with tape or dip them in epoxy, believing they've provided a watertight connection. The Essential Guide to Pool Water Bonding Basics. NOTE: Some text links below go to applicable products on Amazon. To replace a light, therefore, the technician must remove the entire cord and pull the new one in place, a process that can become frustrating when the line gets stuck. Swimming pool equipment pads should be included in the bonding loop since they are, of course, part of the pool system.
Mistakes that electrical professionals see in the field range from the clearly wrong to the more off-base. Brotz sees mis-installed lights, but has witnessed hundreds, or even thousands, of cases where pumps, heat pumps, wires and other components were installed incorrectly. Consequently the pool controls were a little shaky and the upright strut could be easily swayed. If both ends of the pipe have equal pressure the water will not move, regardless of the level of pressure. Since lights and pumps were first introduced to pools, electrocution has been an issue. Most important – any conductive structures within arm's reach of the pool should also be bonded (fences, lamp, ladders, pipework, etc). Any conductive fittings within or attached to the pool structure, such as ladders and diving boards. Errors in the field. A true examination of electrical safety merits a holistic approach, they say, one that accounts not only for safeguards surrounding the vessel, but those around the home as well, because current can travel to the pool from outside its immediate area.

The connections of metal by the copper wire allow for electric flow to pass through metal. Tighten mounting screw. All equipment associated with a pool must be bonded. Consumers constructing new pools are encouraged to consult a licensed electrical contractor early in the planning stage along with the pool builder, fence installer and landscaper. Just as important, an improperly wired low-voltage system still can function as a path for stray current generated from another source: As it seeks to complete the circuit, the current could travel through the grounding wire, for instance, to water.
The wire runs through the earth, not always inside a conduit. When the pool is built, it will incorporate a continuous steel rebar grid within the concrete pool wall. I understand the risk is almost insignificant, but it's not worth it. It is acceptable to use only copper split bolt connectors for the #8 solid copper pool wire. The goal of bonding is to connect, contain and prevent the transmission of any harmful electrical voltage to pool equipment, people and pets. In AS/NZS 3000:2007 Clause 6. "You can have connecting devices that are listed for use underground that won't last a month in a pool environment. Connect the insulated ground wire to the green ground screw near the terminal plate of the motor. Unfortunately, you are not properly water bonding the pool. If one piece of equipment becomes energized from a fault in the system, then there is a difference in potential from one element to the other, causing current from the more energized component to seek a path to the less energized component, in order to equalize. These products are the Pool Defender Water Bond Skimmer, Inline Anode & Water Bond, Pump Water Bond and Econ Union Water Bond. If not, they figure, why is the father trying to impose this change on everybody? But some professionals cross wires or even run them in the same conduit or enclosure, creating a serious hazard: If a high-voltage conductor were to become hot enough to melt the insulation of a low-voltage wire, then the bare wires could touch, causing high voltage to transfer into wires intended to send low voltage. Making a mistake grounding and bonding a swimming pool pump can be deadly.
High voltage then could be sent to the low-voltage light. So how does bonding help? You may have may have seen our recent post on Facebook about the tragic accident that involved a teen, who was electrocuted and drowned, in a pool over Labor Day Weekend. The NEC prohibits splicing of underwater wire connections, so pool and spa lights must be powered by a continuous cord, generally the 50-, 100- or 150-foot one supplied by the manufacturer and sealed to the back of the fixture.
