I also know those same jurisdictions usually end up not renewing the Building Officials contract when the city council finally gets tired of constituent complaints. Junction Boxes and Other Enclosures. If this is the case then this needs to be changed because a 220 volt pump circuit does not provide the necessary isolated neutral wire for the 120 volt light. Section 680-55 b , Supplied by a Flexible Cord, electric equipment that is supplied by a flexible cord shall have all exposed noncurrent-carrying metal parts grounded by an insulated copper equipment grounding conductor that is an integral part of this cord. I believe that is where H. If these conductive parts are mechanically, electrically, and intentionally bonded married together, there is typically no shock hazard present as these conductive parts are always at the same voltage potential.
It's best to run bonding conductors from point to point. If you have any questions, comments, or concerns, please write to sales mindconnection. Consequently, some inspectors have been requiring that a bonding grid similar to the deck bonding for pools be installed around indoor spas or hot tubs. A discussion with a inspector from Indiana had me second guessing that we may have been in error. Keith holds a master electrician license from the State of Texas. You can also find this requirement in Part B, Permanently Installed Pools, 680-20 a , General, Subsection 2.
The Code describes the basic bonding requirements and provides a list of items required to be bonded together. The following equipment shall be grounded: 1 all electric equipment located within the fountain or within 5 ft. If these metallic conductive parts are not bonded together, this leaves these conductive parts having the potential of being at different voltage potentials. The title to Section 680. The transformer shall be an isolated winding type having a grounded metal barrier between the primary and secondary windings.
One of these measures is the bonding together of conductive portions of the pool and metal parts of electrical equipment associated with the pool. Another subtle change that may be overlooked is the change in height requirement in Table 680. Reinforcing steel effectively insulated by an encapsulating, nonconductive compound at the time of manufacture is not required to be bonded. I'm in a discussion friendly one on another forum about article 680. There have been many of conversations on this very subject. This becomes especially significant when dealing with installations covered by Art. This list of five items probably covers everything, but if you make a point of bonding everything metallic then you have certainty and not mere probability.
The first subtle change occurs in Section 680. But are you saying this as a blanket statement for all crawlspaces? Sorry if I tried your patience. An example of this might be raceways installed beneath a concrete pool deck. Recent revisions have inadvertently left holes that fostered misinterpretation and misapplication. Electric Signs and Outline Lighting, Section 600-6 Disconnects, which tells us that the disconnect shall be located in accordance with Section 680-12, Disconnecting Means.
The 2011 Code sought to remedy these problems. If done properly, there will be no current flow between these parts that would be harmful to personnel. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. Will this provide the protection that we need? He can be reached at 919. Now is a good time to explore the different purposes served by bonding and grounding and to develop a clear understanding of the two terms.
Most of us know what these are, but if you don't then here's a working definition applicable to Article 610. Many Code users were unclear if the exception was a carte blanche exception to 680. So be careful to apply the Article 100 definitions. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets. Then solidify your code knowledge through engaging discussion, revised activities, and practical exercises based on key concepts.
This revision should help the Code user understand the scope of this rule. Where the junction box is supported only by the conduit, the conduit shall be of copper, brass, or other approved corrosion-resistant metal. This section previously only required a disconnecting means for pool, spa or hot tub equipment. Similar changes were made throughout Art. Swimming pool with a fountain using the same water This definition was the second sentence in Section 680-1.
For pool water heaters rated at more than 50 amperes and having specific instructions regarding bonding and grounding: only those parts designated to be bonded are required to be bonded; and only those parts designated to be grounded are required to be grounded. While snap switches do require a 5-ft separation from a spa or hot tub, so do circuit breakers, disconnect switches, safety switches, and all other types of switches. A lighting fixture facing upward shall have the lens adequately guarded to prevent contact by any person. Adding those and other electric features makes pools potentially lethal, and the requirements of Article 680 protect against such an outcome. The other three Articles preceding it are 600 Electric Signs and Outline Lighting , Article 604 Manufactured Wiring Systems , and Article 605 Office Furnishings. That includes unpaved, paved, and poured concrete surfaces. Underground wiring shall not be permitted under the pool or within the area extending 1.
