a. All metal parts & surfaces within 5′ of the Hot Tub / Spa must be bonded together using a #8 (or larger) solid copper wire and connections must be non-corrosive.

What is bonding lug on hot tub?
A bonding lug is provided on the heater. With another #8 solid copper wire, bond the pump/motor to the house electrical panel or approved local bond. A bonding lug is provided on the pump/motor. The heaters are typically metal: You can see the lug on the bottom left.
What support does a hot tub need?
Hot tubs need to be placed on a flat, stable and level surface. Concrete slabs are often used for this purpose. Depending on the size of your hot tub, concrete pads that are 3.5 to 4 inches thick are usually installed. Larger hot tubs may require a thicker concrete pad.
Does a concrete pad have to be grounded for a hot tub?
The rebar / wire should be BONDED to the spa system. It should NOT be grounded through a grounding rod. Doing so can actually be dangerous. If you can’t sell it on eBay, it may not even qualify as landfill.
How far away does a GFCI have to be from a hot tub?
Therefore, choosing a GFCI breaker with the proper amperage rating for the hot tub within five feet of the tub would fulfill the NEC requirement for a disconnect and GFCI protection. Required amperage will be specified in the manual or on the nameplate of the unit.
What base should a hot tub sit on?
If you’re having a base installed especially for your Hot Tub we would recommend a patio, decking area or poured concrete base. Whatever you choose make sure whoever installs it for you ensures the base is level and large enough for your Hot Tub and steps.
Can I put a hot tub on pavers?
Patio Pavers Are The Ideal Support For Hot Tubs But before you run out to the hot tub store, consider where you’re going to place it, and what you’re going to place it on. Once the pavers are in place, they will sweep hydrostatic sand into the joints, and you can set your hot tub up as they leave your driveway.
What is the best base to put a hot tub on?
Concrete Base This tends to be a common approach for hot tubs becuase it offers strong support for the weight and also keeps the area nice and clean. Concrete is solid, not overly expensive and is quite easy to lay.
Can concrete be used for grounding?
Instead, you can make your entire home a place to connect with the energy of the Earth with concrete. The home can’t be on an elevated foundation or use a vapor barrier to do it, but it is possible. Concrete is made up of water, sand, crushed stone, and cement (usually with a little bit of air trapped inside, too).
What are the NEC requirements for grounding and bonding rebar?
Rebar in footings shall be used as a grounding electrode if ½ inch or larger in diameter and at least 20 feet in length. Grounding electrodes shall be encased in at least 2 inches of concrete with the concrete in direct contact with the earth.
Why do concrete slabs need to be earthed?
This is to mitigate the touch potential hazard that occurs when a person is standing on the ground while being in contact with the concrete slab since during a fault the ground and the concrete slab will be at a different potential.
How close can the electrical box be to a hot tub?
*The National Electrical Code (NEC) specifies installation of an approved manual disconnect device. It must be adjacent to the hot tub, at least 5 feet away, and within line of sight. The NEC also requires a 120V receptacle within a 10-20 foot distance from the spa.
What wiring does a hot tub need?
For most full-sized spas or hot tubs, the National Electrical Code (NEC) requires: Hard-wiring the spa into a ground fault circuit interrupter (GFCI)-protected 220 to 240V, 50- or 60-amp dedicated circuit.
