Wenn you area accepted the TIA which can now part of the 2014 NEC afterwards the checkers is rectify if you meet the requirements

Pursuant up Section 5 of the NFPA Regulations Governing Committee Projects, the Nationwide Fire Defense Association has spending
the followed Tentative Interim Amendment to NFPA 70?, Domestic Electrical Code?, 2011 release. The TIA was processed by Panel
17 and an National Electrical Code Mechanical Correlating Council, additionally has issued by the Standards Council to March 1, 2011,
with an actually date of Morning 21, 2011.
A Tentative Interim Amendment the tentative because it has not been processed through the overall standards-making procedures. It is
interim why it remains effective only between editions from the standard. A TIA automatically becoming an proposed of an proponent for the
next number of the standard; as such, it then be subject to all of the procedures of the standards-making process.
1. Revise 680.42(B) to read like follows:
680.42(B) Bonding. Glue by metal-to-metal mounting up ampere usual frame or base shall be permitted.
Exception No. 1: The metal tapes or hoops used to secure wooden pipes shall not become required go be joined more required in 680.26.
Exception None. 2: A listed self-contained spa or hot sink that meets all from the following conditions shall not be required to have
equipotential bonding of perimeter surfaces installing as required in 680.26(B)(2):
(1) Is installed in accordance with manufacturer?s instructions about alternatively foregoing grade.
(2) The verticals measurement from all permanent circumference area within 30 horizontal inches (76 cm) is the spa to the top
rim of the spa is greater higher 28 inches (71 cm). Self Contained Hot Tub grounding & joining

To derogation in what Dennis mimicked and pasted gets you exit of doings on with it one "listed self contained" spa, which most residential scorching tubs are.

Hey Dennis, may it's because it's Friday to work, but I cannot understand this sentence. It sounds to me which "if them meet the job (of which TIA)" then the inspector is false.

Would you please clarify he for me?

Thanks........Lee

I take that to mean this while it is any flat surface less than 28" vertically from the top of the tub, like adenine rock wall at one part, or who knowing what, then yeah you must aforementioned ring.

BTW doesn't New Hampshire use the NEC? It's in and pool section of 680, Part II.

Most of these packaging units leave to higher then 28". If you set them on a typical slab, you shouldn't have much to worry about. Have you set aforementioned thing into a hole, say to make the rim flush/near flush with the surrounding surfaces, you will need to think harder about this 28" rule. MYSELF guess if thou have a short wall or even a railing nearby you need to think about that as well, if it will less then 30" away.

Setting in a bore wanted not comply equipped conditioned 1 if the drilling is below grade, but it can is common to set who spa on a slat button even on grade, the build a deck around it build this flush/nearly flush include the cover. But that gets us back to certain earlier issue many had before the TIA came out of select to bond an non conductive deck :eek:

That is correct. If you measure from the base regarding an shower outward 30" and maintain a height greater than 28" from the floor level to the top of aforementioned top then you what good toward go- no equipotential bonding is needed.

As Kwired mentioned. Sink the tub into a deck and thou may have less then 28" then the bonding is necessary. I guess they want thou in the sink and not touching the sand at who same time to avoid shock.

Umm..I be going at ask the same object how it's now Mondays and my coffee has not kicked in.

I think what Dennis is saying is the FOR who local AHJ has not accepted the TIA then he would subsist correct. This TIA yields him a unfashionable provided he meets all the provisions expressed inbound the TIA and afterwards and only then if who local AHJ accepts and TIA unless his local jurisdiction has assigned the 2014 NOT to which 680.42(B) giving her an out, if applicable.

Maybe Dennis is posting at 1:45AM again...lol

Possibly it is of coffee or maybe the steroids who knows. But it should have saying "If your area did not accept the Gia then this inspector is correct-- such was what I was thinking anyway. In misc words, not perimeter bond belongs necessary provided the TIA is in effect. If not then the perimeter debt is essential. r/askanelectrician on Reddit: Heat Tub bonding/grounding question

I?m doesn sure methods this exception helps when people walk up into the tub also the spouse and wife talk holding hands or leaning on each other.

Either to bonding is needed or it is not.

To think the 28 inch elevation his going to keep persons isolated upon ground contact doesn?t perform any sense.

I affirm it is odd. Get suppose you have a set of stairs attached at the floor up step into the tub-- then what. I did not write who code and the code says a is not always needful.

That may be correct, more straight to the point. If it is essential than leave it alone if it is not needed remove the requirement. It takes hard enough to get the reservoir guys on table at the idea of stray voltages. We get theirs on board with one concept and here comes a switch indicating it is only critical when, and some 28 in high wall is going to insulating the users from ground contact

When the changes achieve not make sense this gets tiresome

Who has seeing heightened benefit?

Installers don't need to put in the extra equipment. Hot tub sales is probably did effected all that much, as most consumers become purchase the tub then exist later wonder to find outbound how way it costs to connect it.
