Does a hot tub need equipotential bonding?
Bonding. A self-contained spa or hot tub now does not require an equipotential bonding grid.
Does a hot tub need a ground rod?
No ground rod is required. Any electrical system should have one main ground point. If you ground your tub to a ground rod, then you will create a ground loop between your house groung and you ground rod.
Do you bond a hot tub disconnect?
BONDING/GROUNDING FOR A SPA The structure needs to have two ground rods driven outside near the main disconnect. The only time you should bond metal near a manufactured spa is if they did not provide a #8 bare solid copper under the control panel for the motors or if you have metal near the spa with in 10′.
What is pool equipotential bonding?
Briefly, an equipotential bonding grid is a metallic grid that establishes an equipotential plane (or Faraday Cage) around the pool and deck. The equipotential plane puts all points on the plane at an equal potential to equalize voltage and current that passes through the plane.
How far does a GFCI have to be from a hot tub?
Note: The NEC and many jurisdictions REQUIRE the installation of a 120V outdoor GFCI outlet. It is to be located 10-20 feet away from a spa or pool, for safe operation of corded appliances.
Which of the following items are generally not required to be bonded when installing a spa in an indoor location?
(4) Metal surfaces within 5 ft of the inside walls of an indoor spa or hot tub not separated from the indoor spa or hot tub area by a permanent barrier. Exception No. 1: Nonelectrical equipment, such as towel bars or mirror frames, which aren’t connected to metallic piping, aren’t required to be bonded.
Can you have metal near a hot tub?
Metal parts associated with or in the vicinity of an outdoor spa or hot tub must be bonded together. All metal parts within 1.5 m (5 ft) horizontally and 3.7 m (12 ft) vertically must be bonded together. One or more 8 AWG or larger solid copper conductor(s) can satisfy this bonding grid requirement as well.
Is equipotential bonding required?
The use of equipotential bonding zones is required by OSHA for individuals working with power generation, transmission, and distribution equipment under standard 1910.269.
Does pool bonding need to be continuous?
There is no Code requirement calling for this bonding conductor(s) to be installed “in one continuous length without a splice or joint.” This would be true if this conductor were a grounding electrode conductor [see 250.64(C)], but this conductor is not a grounding electrode conductor (used for grounding), it is a …
Do you need a bond grid under a hot tub?
The grounding is taken care of by the circuit EGC, not a #8. The tub also does not require a bonding grid under it like a hot tub AFAIK. The lug would be used if a bond grid were in place. Thanks for posting that section Mike.
Why is the mixing valve bonded to the tub?
The mixing valve is exposed to anyone in the tub at all times therefore the supply pipes needs to be bonded. What we need to keep in mind is that this bond is installed to protect the person in the tub and to keep everything at the same potential.
Why does water need to be bonded to a tub?
The water cannot get into the tub unless it comes out of the piping system and it is possible and probable that the water can fill while the tub is on therefore requiring the tub to be bonded to the supply piping. The mixing valve is exposed to anyone in the tub at all times therefore the supply pipes needs to be bonded.
