250.122(G) Sizing Equipment Grounds for Feeder Taps “NOT A CODE CHANGE”

Got a call from a contractor stating that the inspector was requiring him to size an equipment ground in a feeder tap based on the feeder main and not the size of tapped main he was installing.  The inspector was correct that the equipment grounds installed with the feeder taps would have to be sized based on the feeder main and not the taps main.  This will only apply when a wire type equipment ground is installed, if you are using metal nipples as the equipment ground then this section does not apply.  In the picture that I used the nipples are metal because I could not find a picture with PVC nipples,  So if these nipples were PVC then the equipment grounds installed would have to be based on this section.  The last part of this section tells us that the equipment ground will not have to be larger than the tap conductors.

This one was sent to me by my son Aaron.  He thought that I would like it, he was right!  I’ll never be able to look at a Safety Pin the same way again.  I’m not sure what they were feeding, but it is a different way of connecting loads to a branch circuit.

Hope you all had a great Thanksgiving.

2017 NEC CODE CHANGE 422.16(B)(2,6) FLEXIBLE CORDS FOR DISHWASHERS, AND TRASH COMPACTORS

A Code change that makes what we have been doing for a long time legal.  The Code changed the maximum length of the cord we put on a dishwasher from 4’ to 6.5’. I think from the 70s to today most have used a 6’ cord if not longer to hook up the dishwasher.

A new change also restricts the location of the receptacle outlet to a space adjacent to the dishwasher, no longer allowing it to be placed behind the unit.  Although I never put an outlet behind the dishwasher it was allowed.

2017 CODE CHANGE TAMPER RESISTANT RECEPTACLES 406.12

This section has been expanded to more commercial areas and mobile homes in the 2017 Code.  This section 406.12 now covers more commercial areas where these types of receptacles are needed. They figured out that children not only get hurt in the home, they can get hurt at the airport, in the doctors office, and in mobile homes. 

This is a 2017 CODE change and it will not go into use until January of 2021.

Code Change 210.8 GFCI protection

This weeks 2017 Code change is not a change but a clarification to a Code section.  It is based on 201.8 GFCI protection and how we measure the distances from a receptacle.

“For the purposes of this section, when determining distance from receptacles the distance shall be measured as the shortest path the cord of an appliance connected to the receptacle would follow without piercing a floor, wall, ceiling, or fixed barrier, or passing through a door, doorway, or window.”

So from the edged of the sink to the receptacle for the disposal you pass through a doorway (most of the time).  Some will say that because the dishwasher is on GFCI it also includes the disposal, that is not the case the dishwasher placement on a GFCI protected circuit was based on a request from the manufacturers to place the dishwasher on a GFCI protected circuit.  Maybe some day it will be required to be on a GFCI circuit but not in the 2017 Code.

My last post for the lug guards was also a 2017 NEC Code change.
