I am starting to read the Mike Holt and EC&M articles in the new code and the first one that grabbed me was NFPA requiring torque tools just about everywhere. I bet Ideal and Klein are ready to roll out some new "clicker" screwdrivers for binding screws and bus bars. Since they didn't actually specify any required calibration regimes or standards, I wonder how many guys will just count on the torque collar on their drill/driver?
My last 7 or 8 years in the computer biz we were ISO/9000 with standards and practices for just about everything including calibrating any tool that measured anything (certified labs, tracking logs etc) so I know this can get complicated if they want it to be.

What other changes do you see as being significant?

Massachusetts has adopted the 2020 as of Janruary 1st...

Some of the significant changes are...

230.85 Emergency Disconnect outside for 1 & 2 Family Dwellings

230.71 Single disconnect unless separate enclosures or compartmentalized equipment. No more 6-switches in one piece of equipment. Impacts meter-mains with 2 breakers and meter packs up to 6 mains. Manufacturers will need to redesign equipment if contractors are to continue the use...or a main switch is needed.

230.67 surge protection for dwelling units...and that is ALL dwelling units.

250.25 Supply-side connected enclosures (ie PV disconnect) need to be grounding like a Service Disconnect !!!

250.64(B)(2) requires SCH 80 for GEC protection if PVC is used.

210.8(A)& (B) has many new GFCI rules such as all basement receptacles including finished areas, dryers need GFCI and range receptacle if within 6ft of sink, and 210.8(F) all outdoor outlets ( Mass deleted this one)

That's just a few. There is alot of changes and reorganization. Things are not what and where they used to be. But table 310.15(B)(16) is back to 310.16 !!!

The softcover Code book cover is cheap without the prior gloss finish... well at least my first edition release is. I covered mine with sheets protectors in hopes it would last for 3-years.

When they moved 310.16 back, did they restore the ampacity for #12 & 14 in the 60c column?

Thanks shortcircuit for the partial list. I have just ordered mine and have not received it yet. This gives me a good place to start looking things up.

It now is required to use GFCI to protect the Disposal receptacle and Instant Hot receptacle in the sink base. The door on the sink base cabinet is not an issue.

OK, here in NJ we are under the '14 until March 3rd (Grace Period for submittals), As of March 3rd, 2017 is enforced with some amendments.

We have Continuing Ed on the 2020 starting real soon, but I have to go over the '17 Changes.

Confusing??
