I would like to comment on this....but I have not seen any of the '17 changes as of yet.

NJ is not one to adopt a 'new' NEC quickly. I think when I get back to the office Wed. I'll have one of the clerical staff order the '17.

PS: Anyone have any comments??

Sorry, I'm not up on the 2017 NEC either.

I think I made a significant change to a prior NEC, but will never get the credit for that.

The last time I had a proposal "accepted in principle" was about LEDs in closets.
Florida is always a cycle or 2 behind so it will be a while before I get serious about the 17.

We're on the '17 in Vermont , this new inclusion in 110.14 caused quite the flap

>>>

Quote

110.14(D) Installation. Where a tightening torque is indicated as a
numeric value on equipment or in installation instructions
provided by the manufacturer, a calibrated torque tool shall be
used to achieve the indicated torque value, unless the equip‐
ment manufacturer has provided installation instructions for
an alternative method of achieving the required torque.

Apparently someone just had to ask about torque wrench calibration.....and it all went off in the ozone with certifications and qualified testers, etc....

It's Vermont , boring without snow.....

This one has many wondering where to purchase what's needed....>>

Quote

210.8(B) Other Than Dwelling Units. All single-phase receptacles
rated 150 volts to ground or less, 50 amperes or less and three-
phase receptacles rated 150 volts to ground or less,
100 amperes or less installed in the following locations shall
have ground-fault circuit-interrupter protection for personnel.

But by far and large, the one '17 change that left everyone in class with that 'kicked in the pants' look was this>>>

Quote

215.2 A 1 Exception No. 2: Where a portion of a feeder is connected at both its
supply and load ends to separately installed pressure connections as
covered in 110.14(C)(2), it shall be permitted to have an allowable
ampacity not less than the sum of the continuous load plus the noncon‐
tinuous load. No portion of a feeder installed under the provisions of
this exception shall extend into an enclosure containing either the feeder
supply or the feeder load terminations, as covered in 110.14(C)(1).

This is hard for me to 'splain , especialy w/o the HB pix .

It's essentially saying we can run a feeder @ 90C

There's a 1/2 page of if's & buts.....

I still don't get it...:(

It’s been a while, so.....hello & welcome!!

The torque wrench thing will create debate, as you infer about calibrate.

I have to think about you second post a little bit

The third has my head spinning.

I'd be willing to bet that the torque thing is just to make sure that everyone has one to use instead of trusting the torque standard that we were to at Ford which was "tighten it until it snaps...then back it off a quarter turn".
Something tells me that nobody (except perhaps the truly anal AHJ's) will care about having a recent testing certification.

FWIW. I know of two AHJs that are going to love the calibration thing..

I do not ‘witness test’, and I am not aware of any other inspectors who want to see/check any torque readings. Basically, it’s on the contractor, or the project design pro/engineer.
